Own business: production and sale of plastic pipes

Industrial production

The Russian market for the production of pipes from various plastic has expanded significantly in recent years. This is due to the simple production technology, as well as the high demand for this product. Plastic pipes are widely used. They are used in sewer and heating systems, in water and gas supply systems, as well as for the arrangement of a “warm floor”. Such a wide range of applications is explained by the qualitative characteristics of plastic pipes:

  • they are durable, do not rust, do not rot;
  • withstand temperatures up to 160 -170? C;
  • do not change the taste of water;
  • there are no calcareous deposits on them;
  • shelf life of about 50 years;
  • five to seven times lighter than metal pipes.

Pipe manufacturers are improving the technology and expanding the assortment, because the competition in this type of production is quite high. For a successful pipe sales business, you need to produce quality goods at an affordable price.

Technology and raw materials

For the manufacture of plastic pipes, various raw materials are used: high and low pressure polymers, polypropylene, polybutene, polyvinyl chloride, etc. Their production is environmentally friendly and uncomplicated; it is based on extrusion. Extrusion is the extrusion of pipes from molten plastic using a special machine (extruder). There are several types of extruders: screw, screwless and combined. The principle of operation of a screw extruder resembles a meat grinder, or juicer. For screwless, the main working part is the disk; they are used, if necessary, to produce pipes from mixed materials. The combined extruder combines both a screw part and a disk. Screw extruders are most commonly used. They are single and two-stage, specialized and universal, single and twin-screw, equipped with a degassing chamber and without it, with screws rotating in one or in opposite directions, etc.

The production of plastic pipes is as follows. The raw materials in granules are filled up with the hopper-receiver of the extruder, where it melts under high temperature. Next, the mass is extruded through the forming head of the extruder, which determines the parameters of the future pipe. After the initial molding, the pulling machine pulls the workpiece into the bath for primary cooling, where, under the influence of pressure, it is finally formed using a calibrating mold. Next, the pipe is cut and either laid in stacks (pipes of large diameter) or coiled up (pipes of small diameter).

Equipment and raw materials

The full-cycle plastic pipe production line, in addition to the extruder, includes a pipe-cutting machine, a feed system, a bath for calibration and cooling, a mixer, a haul-off device, a conveyor belt, a vacuum moulder, and a pipe stacker.

Productivity depends on the size of the pipe: pipe diameter - 20.25, - 80 kg / h, pipe diameter - 32.40.50 - 100 kg / h, pipe diameter - 63.75.900.10 - 130 kg / h. A line can produce about 1000 meters of pipes per day, depending on the diameter. Lines have different parameters, so you can order machines for your business, and you can save and buy used equipment. The lowest cost of such a set is about 400 thousand rubles.

Granular polymers are purchased for raw materials. It is important to be demanding on its quality and shelf life. Polyethylene and polypropylene are very beneficial materials due to their almost unlimited shelf life. Polypropylene copolymer is one of the best materials for the manufacture of pipes. Its cost is about 50-70 rubles per kg. Low-pressure polyethylene (HDPE) is also often used for production, its cost is lower - about 32 rubles per kg and above. The best option would be to arrange delivery from one plant, because a change in raw materials will require a change in the characteristics of the equipment.

Room and staff

For the production of plastic pipes, any room outside the city that has a convenient entrance, where you can locate a workshop, a large warehouse, a bathroom, premises for staff, is suitable. All equipment can be located in the workshop area from 40 sq. M to 200 sq. M. For its maintenance you will need from 3 people per shift. It is necessary to hire technologists, operators on machines, auxiliary workers. The average salary of a technologist is about 50 thousand rubles, workers - about 25-30 thousand rubles.


To start production, you will need to obtain permits from the gas service, the fire inspectorate, sanitary and epidemiological station, the local department of the State Supervision Service, local executive authorities, etc.

According to GOST 18599-2001, the conditions for the transportation and storage of plastic pipes are as follows.

It is allowed to transport pipes by any type of transport in covered bodies (wagons). To protect the pipes from dust and external influences, they must be closed with plugs and placed in the package. The weight of the pipe coils together with the package should not exceed 1.25 tons, the pipe length should not exceed 5.5 m.

They store pipes in warehouses in a horizontal position far from sunlight and heating appliances. The stack height when storing pipes over 2 months should not exceed 2m. When stored up to 2 months, the height of the stack should be no more than 3m. Pipe storage is possible for no more than 12 months. Shelf life - 2 years from the date of manufacture.

Investment and sale

The initial investment required to start the production of plastic pipes, when buying used equipment and 100 tons of raw materials, will be about 8-9 million rubles (taking into account six months' salary and rent). Business pays off in about 1.5-2 years. Profitability can vary greatly (from 2 to 20%), which is associated with competition.

The average price per meter of pipe in the market depends on its parameters: if a pipe with a diameter of 63 mm costs about 90 rubles, then with a diameter of 800 mm it is already about 14 thousand rubles. When searching for consumers, remember the areas of application for plastic pipes mentioned above. You can establish contacts with local companies involved in the installation of pipes and their installation, and custom-made pipes.
