Recent years The attention of many entrepreneurs is attracted by the production of plastic pipes. Companies open their own workshops where they produce PVC products.
What is the reason for its popularity? In improving production, growing demand and widespread use of polymer, cylindrical products. Due to the emergence of more and more new players in the market, fierce competition has formed.
But by offering a high-quality product at an attractive price for customers, you can bypass many of them.
Why make pipes from plastic?
Plastic production will bring a stable profit to the business owner. Plastic is a material that, since 2010, has been considered superior to others in construction and other fields.
This boom was caused by its convenience and practicality, minimal resource consumption and other operational characteristics. Pipes made from plastic also have a number of advantages, which to this day make these products in demand on the market.
Plastic cylindrical products are also characterized by:
- resistance to high temperature (maximum 170°C), rotting, dynamic loads, abrasion;
- light weight;
- fire safety and safety for drinking water supply;
- seismic resistance;
- flexibility;
- economical operation.
Although the fashion trends for plastic have slowed down a bit, pipes made from this material are still being sold successfully. This is one of the reasons that the business of their production has good returns and is promising.
Excellent sales volumes are also influenced by the widespread use of plastic pipes. The list is really large, but we will list the main areas.
- sewer systems;
- water supply;
- cable channels;
- heating;
- transportation of liquids in industrial production;
- intra-house networks;
- drainage systems;
- installation of watering and irrigation systems;
- gas distribution, etc.
The future entrepreneur will have difficulties when entering the market, since there is a lot of competition in this area. However, this should not “discourage” such activities as the production of plastic pipes.
If you are making wide range products good quality at an attractive price, and are ready to fight for end consumers, using available resources and proactive strategies, gaining a strong position will become an achievable goal.
Procedure for starting a plastic pipe production
As in any entrepreneurial activity, first of all you need to do something, which will become your guide to action, help you avoid many mistakes and indicate what financial support is needed to start production.
Before writing it, the entrepreneur should already have ideas about the plastic pipe market and the competitive environment, which are formed during the analysis (we will return to this in more detail). Of course, you will have to delve into production technology, think about where and how you will buy raw materials and equipment.
No less important is the question regarding labor resources and production areas, formation of assortment. In addition, the production of plastic pipes requires registration and the choice of a tax regime.
Because pipe production occurs with, it is classified as harmful. Therefore, it is necessary to comply with international law regarding the care of environment, ensure her safety.
All types of products must also have certificates of conformity. The company must implement a Quality and Environmental Policy.
1. Analysis of the market and the polymer pipe industry.
The Russian market for plastic pipes is to some extent limited and narrowed in volume due to a lack of raw materials and final demand. The problem is counterfeit goods and savings on production costs.
In 2016, sales of plastic pipes had stable dynamics. If compared with 2014, it will be negative.
Consumption remained at 425 thousand tons. Enterprises that updated and expanded production capacities produced more plastic products, and although consumption increased by 2016, supply exceeded demand.
The production of pressure plastic pipes predominated (60%), non-pressure pipes were produced least of all (19%), and corrugated products accounted for 21%. At the same time, record supplies of domestic raw materials (75 thousand tons of polypropylene of various types) became an incentive to increase production.
There is a tendency for foreign companies involved in the supply of pipes to be squeezed out of the market. In this industry, the consumption level of polyethylene pipes exceeded 62%.
The main production facilities are involved in the production of PE pipes large diameter, intended for use in water supply and gas distribution. There is the toughest competition here and there is practically no import.
In 2016, there was a decrease in import supplies of equipment used in the production of plastic pipes. China remains the main supplier. It provides Russia with 70% automatic lines.
The main issue for plastic pipe manufacturers is the supply of raw materials. Moreover, few pipe business owners are confident that a decrease in the price of raw materials will increase the production of plastic pipes.
By 2020, production volumes of polypropylene and polyethylene are expected to increase by 30%.
The competition is:
- Cheboksary Pipe Plant;
- Polymer piping systems;
- Polyplastic Group;
- Techstroy;
- About Aqua;
- Politek;
- PC Contour;
- Hemcor;
- Pieplough et al.
In general, the production of polymer pipes in Russia can be called oligopolistic, since the main part of the market is occupied by 8 large enterprises. And although these positions are only becoming stronger, conditions are being created for small and medium-sized companies to actively develop their business.
Production efficiency is achieved through the use of new technologies, the introduction of innovations, and the production of unique plastic products. This creates the need to purchase expensive equipment.
The reform of the housing and communal services sector and the modernization of infrastructure have a great influence on the development of the market.
2. Type of plastic pipes: what products to produce?
To decide on the assortment that an entrepreneur will produce and sell, you should understand the types of plastic pipes:
PE pipes They transport water well for drinking and household needs, and are used for drainage. Such products are produced with a length of at least 12 m and a diameter of 1.6-16 cm. Products can be found under the brands PE 63, 80, 100, 100...etc.
The production of polyethylene pipes has its own characteristics:
- use of advanced technologies,
- lower cost,
- less expensive packaging.
The degree of polymerization allows the production of products of different pressures.
PVC pipes are produced in a non-pressure type, they are not afraid of low temperatures and other climatic changes, and are durable. These items are intended for the installation of underground pipelines, sewage systems, and the removal of gaseous media whose temperature does not exceed 45°C.
Also used in construction because... have good economic performance. Their diameter is 11-63 cm, and their length is up to 12 m. They are painted white and orange.
Polypropylene products due to their multi-layer nature and high stiffness class, they cope well with bridging drinking water. PPs are also bought for modernization heating system, technological installations. The diameter range is 2-11 cm. They are supplied in lengths from 2 to 4 m.
Metal-plastic pipes are considered the best option for home use,
because they are easy to install. However, with mechanical deformation, PP quickly breaks, and the connecting elements are not resistant to high temperature changes in water.
The color of the products indicates their area of application. Yes, products blue serves for summing up cold water. White pipes are needed in the installation of hot pipelines and heating. Products with a red color are used for laying heated floors. Yellow pipes are used in gas supply.
The cost of pipes depends on their parameters, i.e. on thickness, diameter, length, layering. In addition, the pricing policy is formed based on the technical characteristics of the product (pressure and temperature of the environment that it can withstand).
The most popular are polyethylene pipes stamps 80, 63 and 100. Prices vary from 15 to 860 rubles.
3. What raw materials are purchased for the production of plastic pipes?
In order for the production of polymer pipes to be carried out without problems, it is necessary to worry about the supply of raw materials. In the future, polymer supplies should occur regularly.
Used as raw material:
- polybutylene (PB),
- polyethylene (PE),
- polyvinchloride (PVC),
- polyamide (PA),
- polypropylene (PP) and other propylenes.
Raw materials are purchased in the primary grade in granulated form.
The type of production will influence the choice of raw materials. When purchasing it, pay attention to expiration date and quality. The most commonly purchased copolymer is polypropylene. This composite allows for the production of durable products.
The backup option is secondary raw materials, also known as waste. This will be used to make plastic pipes. low pressure, which stand for HDPE.
At the stage of preparing production for launch, the workshop owner must find suppliers. You can sign supply agreements both with Russian enterprises engaged in the production of polymers and with foreign ones. The price for domestic primary raw materials is up to 80 rubles/kg, prices for secondary materials are from 30 to 40 rubles/kg.
List of presenters Russian manufacturers polymer granules for plastic pipes:
- Polyplastic— produces recycled polyethylene and other polymer materials at an affordable price.
- Roekoplast– a company producing LDPE and HDPE granules.
- Polymer Club– carries out the production of raw materials for the manufacture of pipes, packaging, films, etc.
- AST Promplast– produces and sells LDPE granules.
- GlavTehProm– is a trading and production company in the field of polymers, rubber goods, and ATI.
- TD Plastics Group– supplier and manufacturer of synthetic polymers.
Production technology: how to make plastic pipes?
The production of plastic pipes is carried out using relatively simple technology. The principle of extrusion is used, when pipes of the required shape are extruded from softened plastic using special equipment - an extruder.
The production process begins with loading raw material granules into the machine hopper. It crushes and liquefies the plastic. The formed mass is squeezed into tanks.
The plastic blanks are immediately given the required shape. They are then pulled out and dipped into a cooling container, where, through pressure and calibration, the “semi-finished products” are processed and given a finished appearance.
The last stage of production consists of cutting plastic products. They are twisted in coils or stacked if they have a large diameter.
Location of an enterprise for the production of polymer pipes
You will need to rent a room outside the city with an area of 40-200 square meters. m. It is necessary that convenient transport access be provided to the workshop. There are no increased power requirements.
Be sure to allocate a large space for storage. A room for personnel (production, administrative) and a bathroom are also required.
In addition, the room must have:
- water supply,
- sewerage,
- ventilation,
- heating,
- fire protection system.
Rent a room with high ceilings. This is due to the bulkiness and height of the machines. High humidity is not allowed in the workshop. Therefore, it is better to buy a hygrometer and monitor this parameter.
Equipment for plastic pipes – we equip production.
To produce plastic pipe products, an entrepreneur must automate the production process by means, the main one of which will be an extruder.
This is a machine designed for plasticization, and it comes in various types.
Screw They work on the principle of a meat grinder. Screwless The devices are used for the production of plastic pipe products from mixed raw materials. Combined The machines are equipped with both disk and screw mechanisms.
Typically, in the production of plastic pipes, screw-type equipment is used; it is considered the simplest, and also has its own classification:
To figure out which extruder is needed in your case, it is better to contact a specialist.
Or you can buy an automated line for production, which will consist of the following elements:
Equipment for plastic pipes is purchased from Russian suppliers, as well as imported. Those who have a limited budget have the opportunity to purchase used machines. The prices for new cars are considerable - from 2 to 4.5 million rubles.
Personnel of the enterprise for the production of plastic pipes
To participate in production, 3 workers (shift) will be required. This is an operator, technologist and assistant. A technologist is entitled to a salary of at least 50 thousand rubles, and an operator – up to 30 thousand rubles.
Regardless of whether they have experience working with such equipment or not, instruction must be provided.
If you yourself cannot control the production process, you will still need to hire a manager. IN mandatory The company must have an accountant and a sales manager. It is advisable to hire a cleaner.
If you intend to install standard equipment and increase production volumes, you may need to increase staffing to 6 people per shift.
If you plan to provide production with transport logistics, you should take into account that these are additional costs, and special requirements are imposed on vehicles.
Having formed a team, it also needs to be retained. To do this, it is necessary to create a healthy psychological climate in it, introduce it, provide normal working conditions, and social guarantees.
It is important to motivate employees with rewards, which will help achieve their goals in a shorter time.
Sales of plastic pipes
If you do not pay serious attention to product sales and do not think about it in advance, the production of plastic pipes will become unprofitable. It is necessary to make a lot of effort to find your clients, wholesale customers and conclude profitable contracts with them.You need to offer plastic products:
- construction bases and shops;
- to private individuals;
- various companies;
- Housing and communal services, etc.
We will have to develop all kinds of discounts, make special offers, and hold promotions. To position your brand, don’t skimp on advertising. Use methods available in the real environment (media, television, radio, outdoor advertising, distribution of leaflets, etc.) and on the Internet.
Creating your own website will be an excellent solution, because this way you will expand your audience and give customers the opportunity to order pipes online.

Plastic pipes are a popular product that is widely used in construction, agriculture and water supply. The demand for them has been and remains high today. At the same time, their production technology is quite simple and accessible for a startup to implement. Today we’ll look at a business idea for manufacturing plastic pipes.
A few words about technology and raw materials
Plastic pipes are made from various materials(PVC, polybutene, polymers), but the process of their creation is simple and does not pollute the environment. Pipes are produced by extrusion, that is, extrusion from molten plastic.
There are several types of extruder:
- Screw.
- Combined.
- Screwless.
The first option resembles a meat grinder in its operation. The screwless one operates with a disk, while the combined one combines the principle of the two types listed above. Study the specialized literature in detail and talk to experts to choose the best option for your business.
Operating procedure
Pipe production is divided into stages:
- Introduction of raw materials into the receiving hopper: plastic granules, which begin to melt at high temperatures.
- The newly formed composition is passed through the extruder head, taking on the shape and dimensions specified by the manufacturer.
- The pipe enters the container of the pulling machine. High blood pressure provides final processing - giving shape and diameter.
- Pipes are cut, stacked or wound into coils.
Equipment and production
To organize the plant’s workflow, you will need to purchase:
- Extruder.
- Slicing unit.
- Apparatus for transporting raw materials.
- Container for calibration and cooling.
- Mixer.
- Pulling device.
- Conveyor.
- Former with vacuum installation.
- Storage and stackers.
The productivity of the workshop depends on the characteristics of the pipes (diameter). The average is 1000 meters of pipes/shift. The indicator may vary depending on the characteristics of the equipment. Check the information in advance before purchasing units.
The raw materials for making pipes are plastic granular polymers. Choose the source material responsibly and pay attention to its expiration date. To produce quality pipes, use propylene copolymer, polypropylene or polyethylene. These are high-quality raw materials at a low price.
Advice! When changing raw materials, you need to change the equipment settings. To avoid wasting time, purchase several lines or initially determine the working material.
Premises and staff
The plant is located outside the city on an area with free access. The equipment occupies from 40 to 200 sq. m of area, the rest of the premises is intended for staff (locker rooms, kitchens, bathrooms), storage finished products and raw materials.
The staff of one shift includes the following positions:
- Technologist.
- Support workers.
- Production line operators.
Registration
To operate an enterprise, you need to obtain permission from the gas service, inspection fire safety, Gosnadzorohrantruda, SES. Study the rules for storing finished products and other organizational issues so that in the future there will be no problems with executive authorities.
Rough calculations show that the investment for the purchase of used equipment and the purchase of raw materials in the amount of 100 tons is 8-9 million rubles. The calculations include rent for the premises for a period of six months. Business profitability varies between 2-20%, which is due to competition. The payback period of the project is 1.5-2 years.
Search for buyers based on the demand for the product. These can be utilities, wholesale and retail stores. Send a business proposal to construction companies.
As a result
Before opening a business, immediately make a list of potential buyers and study the market in your region. There are often problems with implementation. This approach will help prevent a negative development scenario and determine in advance the feasibility of production.
PVC pipes are pioneers among polymer pipes, which began their journey more than half a century ago in America and Europe. In the domestic market, PVC pipes gained popularity extremely slowly. This is explained both by the conservatism of the consumer and the lack of a full-fledged regulatory framework that allows the widespread use of PVC pipes in housing and communal services.
Slowly but surely, pipes made from polymers of this group are constantly expanding their sector in the pipe products market due to improvements quality characteristics pipelines. This is achieved thanks to the emergence of not only innovative technologies for the production of PVC pipes, but also new methods of installing pipeline networks.
The raw material for the production of PVC pipes is granulated PVC polymer.
To create a full range of required properties, a number of additives are used in the manufacture of these products:
- catalysts that accelerate the polymerization reaction;
- inhibitors used to slow down unwanted processes;
- stabilizers that impart stability to the resulting polymer;
- plasticizers that provide the polymer with the necessary plasticity parameters;
- antistatic additives help eliminate static electricity charges;
- Pigments make it possible to obtain the required color of the manufactured pipe.

Other components can be added to the standard composition to impart certain properties to the product. Supplements, as a rule, are manufactured abroad.
Equipment for the production of PVC pipes
An extrusion line for the production of PVC pipes provides a continuous cycle consisting of the stages of extrusion (pushing the material through the molding hole), calibration and cooling in baths, drawing, cutting the pipe to a given length and laying the finished product.
The extrusion line includes:
- an extruder consisting of an extrusion head and a granular raw material supply system;
- baths designed for calibrating and cooling pipes;
- pulling device;
- a mechanism for cutting the resulting pipe into measured lengths - disk cutters or guillotine shears;
- stacker or automatic winder of small diameter pipes.
The extrusion head may have constructive solution in the form of a single block with a flange for fixation to the material cylinder. Consists of the following elements: body, matrix, divider, mandrel holder.
The matrix is centered relative to the position of the mandrel using adjusting bolts. The uniformity of the diameter of the pipe wall thickness depends on the accuracy of alignment.
The German company Krauss Maffei specializes in the production of high-performance extrusion lines for the production of pressure and non-pressure PVC pipes. The largest plant for the production of PVC pipes in Russia, JSC Hemkor, uses several such lines. The quality of the plant's products has increased thanks to the introduction of a gravimetric dosing system for raw polymer.
Extrusion technology for the production of PVC pipes
The process of producing pipes from polymers is relatively simple, environmentally friendly, requires little labor and electrical energy. The area required to install and operate a complete line for the production of polymer pipes is only about 100m2.
The production of PVC pipes begins with pouring granular polymer into a hopper 
extruder. In the extruder, a screw made of high-quality nitrided steel rotating inside a material cylinder mixes the incoming granules. During rotation, the material is heated to a predetermined temperature.
The molten polymer is fed into the extrusion head, where the forming elements of the cylindrical surfaces are:
- mandrel - it is responsible for the formation of the internal diameter,
- a matrix involved in the formation of the outer diameter.
At the exit from the extrusion head, a plasticized blank in the form of a pipe is obtained. To give the pipe blank the required outer and inner diameters, ensuring uniform wall thickness along the diameter, it is calibrated in a vacuum calibrator (bath).
The calibrator is a stainless steel container three meters long, at the ends of which rubber cuffs are installed to ensure tightness.
The outer diameter calibration device is located at the front of the bath and is a stainless steel cylinder with a central hole whose diameter is equal to the diameter of the pipe. Through the diaphragm of the calibrating device, the pipe enters the cooling bath, in which a vacuum is also maintained.
To stretch the pipe evenly, tracked or belt-type pulling devices are used. Pipe cutting is carried out circular saws or guillotine shears. At the end of the line there are devices for laying products on a special rack or for winding small-diameter pipes. These devices can operate in both manual and automatic modes.
The production of PVC sewer pipes, which belong to the non-pressure category, can be focused on the production of pipes with a single-layer wall (monolithic pipes) or with a three-layer wall. The outer layers of a three-layer pipe are made of virgin uPVC. The intermediate layer has a porous structure, and is made from either our own recycled uPVC or a third-party recycled polymer.
The production of corrugated PVC pipes is most often carried out by the method of twin-screw extrusion of two-layer pipes. Inner surface– smooth cylindrical, outer – corrugated wavy. Both walls are produced simultaneously using the hot method and form a single monolithic structure. The cavities formed between the outer and inner walls facilitate the construction of the pipe. The outer wavy wall helps achieve the required annular rigidity.
Process Innovation
One of the innovations in the production of PVC pipes is the production of biaxially oriented pipes. These products have high levels of impact strength and other mechanical characteristics with a simultaneous reduction in wall thickness, pipe weight, and, consequently, its cost.
Currently, two methods of biaxial orientation of PVC pipes are used:
- The two-stage batch method consists of extruding the product and its subsequent biaxial orientation in two different installations. This production is quite energy-intensive and labor-intensive, but makes it possible to obtain products of very high quality.
- In the second method, extrusion with orientation in both directions is carried out on the same line. This production requires high qualifications and is unprofitable in small-scale production.
Since the production of PVC pipes is not a very complicated and labor-intensive process, and the demand for such products is constantly increasing, this direction is promising for those who want to organize their own business. The payback time for the investment depends on the level of equipment utilization. At 50% utilization of the extrusion line, the costs are recouped in about a year.
The products are lightweight, durable and high-strength products made from polyvinyl chloride, not exposed to corrosion and acidic environments. They are fireproof, environmentally friendly, and very easy and quick to install.
These pipes can be used almost everywhere: for draining sewage, supplying drinking water, in drainage and cable systems etc.
Required equipment
To organize the production of PVC pipes, the following minimum set of equipment is required:
- Bunker.
- Extruder.
- Baths where the product is cooled and calibrated.
- Pulling device.
- Cutting mechanism (guillotine shears, disc cutters).
- Additional devices and accessories.
The cost of an extrusion line depends on its functionality and productivity. For example, from the same manufacturer there are models that cost 1,430,000 rubles (LPT 35 - 3/40) and 7,455,000 rubles (LPT 125 - 160/450). The cost depends on the specific productivity and degree of automation.
If we consider the issue of purchasing used equipment, then you can purchase a line for 500,000 rubles. However, such savings may lead to additional difficulties with repairs and adjustments.
WITH detailed description extrusion line you can find in the section equipment for the production of PVC pipes.
An example of organizing a business for the production of PVC pipes.
Let us consider, as an example, the organization of production on an LPT 63 20x110 extrusion line. Its purchase will cost 1,720,000 rubles
Delivery and commissioning will range from 3% to 5% of the cost of the line (from 50,000 rubles).
In our case, the equipment will be exclusively engaged in the production of PVC sewer pipes 50x1.8 mm (weight of one meter - 0.6 kg).
According to the technical specifications, the extruder productivity can reach 80 kg/h. This means that with uninterrupted operation of the equipment, you can get 133 linear meters per hour (productivity \ weight of the product). Thus, the monthly “performance” of the line at full load will be equal to 95,760 linear meters. Let's assume that the equipment operates in two shifts with one day off. In this case, its productivity will be in the region of 51,100 linear meters/month. (i.e. 54% load)
To operate in this mode, a minimum of 34 tons of raw materials (80 kg/h x 16 hours x 26 days) per month is required. Let's assume that Chinese-made SG-5 PVC will be used, its average cost is 44 rubles / kg.
Thus, the cost of raw materials will be approximately 1,496,000 rubles per month.
Regarding personnel, we will proceed from the fact that two people work on each shift - an operator and an assistant. Their salary, of course, is determined on an individual basis. To begin with, let it be 15,000 rubles per person, a total of 60,000 rubles for four per month.
If you take 45 rubles for one linear meter of finished products, you get a gross income of around 2,300,000 rubles per month. The monthly profit in this case will be 744,000 rubles (2,300,000 - 1,496,000 - 60,000) without taking into account the costs of rent, utilities and other organizational expenses.
Conclusions
To organize the production of PVC pipes with a capacity of 100 thousand linear meters per month, a starting capital of at least 4.5 million rubles is required. This includes the cost of the line (1,800,000 rubles plus delivery costs), its maintenance and personnel training (from 50,000 rubles), the cost of raw materials (2,000,000 rubles), repairs and preparation of the premises (500,000 rubles), other expenses (RUB 200,000).
Payback periods depend, first of all, on the degree of equipment utilization, so with 50% equipment utilization, the payback period will be 10-12 months.
First you need to rent a small plant or part production premises outside the city. Mandatory conditions: good transport accessibility, convenient access roads, area of at least 200 sq.m. There must be 380 volt electricity, sewerage, and water supply.
It is important to provide several zones separated from each other:
- production workshop;
- warehouse complex;
- bathroom;
- premises for employees.
Taking into account the fact that the pipe production line includes tall and heavy equipment, the ceiling height must be at least 10 m. Powerful air conditioners and fire protection systems must be installed in the workshop. The storage area should have normal humidity and room temperature.
Hiring and organizational issues
When organizing a line standard size and staffing it is necessary to hire about six workers. This is necessary to ensure uninterrupted production (three employees per shift).
Additionally, it is necessary to hire an accountant, auxiliary workers, a process engineer, and two machine operators. Thus, the list of monthly expenses will need to include $6,000 as employee salaries.
Since the business of manufacturing HDPE pipes belongs to the category of technically complex industries, at the stages of its organization you will need to obtain permission from the local administration, the Sanitary and Epidemiological Station, the State Energy Supervision Authority, and the fire inspectorate. As for registration, the optimal form is LLC.
Equipment for the production of polyethylene pipes
You can purchase both new and used equipment of domestic or foreign production. When purchasing a line Russian production you can save some money.
List of required line components:
- dryers;
- automatic loader;
- screw extruder;
- containers for cooling workpieces;
- conveyor;
- coronator;
- device for marking products;
- control system;
- auto stacker;
- vacuum calibrator.
Raw materials for the production of polyethylene pipes
Products for the manufacture of HDPE pipes are selected individually. High-quality raw materials are polymers of different pressures, polypropylene, polyvinyl chloride,.
Raw materials should be ordered from trusted suppliers. The highest quality and most reliable brands are Hastalen 5416 (Bazell), Vestalen 9412 (SABIC), imported.
Technology for the production of polyethylene pipes
The pipe manufacturing process is based on the extrusion method. The essence lies in the homogenization of raw materials in order to soften them in a special device - an extruder. With the help of equipment dies, pipes are formed to a specified diameter and then cooled.
In the first step, the material is placed into the extruder receiving device. Next, the raw material is moved into a preheated cylinder. Gradually, the material is transferred to the hottest parts of the cylinder, slowly warming up.
Thus, the cylinder consists of three components: a feeder, a raw material compression zone, and a dispensing zone. The high quality of the extruder die is important, since the size of the finished pipes depends on it. It must be maintained at a fixed temperature.
After the raw materials pass through the cylinder and the blanks are obtained, they are placed in a container for vacuum molding under pressure. The pipes are then removed from the cooling chamber and immediately transferred to the conveyor to prevent its deformation.
At the final stage, the pipes are cut and laid into prepared coils. For cutting, special saws or cutters are used (depending on the selected diameter).
Investments and income
In order to launch the production of HDPE pipes, at least $140 thousand will be required. This includes the cost of monthly rent, wages, repairs of rented premises, purchase of equipment and raw materials.
The price of a finished product unit depends on its type. In this case, the rule applies: the larger the diameter, the more expensive the product.
With full sales of products, monthly income can be up to $6,000. The investment pays off in about 2 years.
Polyethylene is serious business. It requires not only large financial investments, but also professional knowledge in the field of production and experience in managing a large organization.
