MPC – polimerne cevi ojačane čvrstom rešetkom zavarenom od čelične žice

Production and transport of oil and gas, gas networks with working pressure of 40 to 90 atmospheres (depending on diameter)

The priority of the MPC selection in these sectors is the minimum price for maintaining such a pipeline, calculated on the basis of long-term work.

Transport of acids, alkaline liquids and products with high salt content

It is known that polymeric materials have very high acid and alkaline resistance. The materials used in MPC production are not exceptions, but due to their high pipe strength, such products can be transported over long distances. The high effect is the use of MPCs when transporting corrosive acids, including hydrofluoric, for example, in the production of mineral fertilizers.

During the drilling of artificial wells as a casing

Our metal-plastic pipes were originally made for use as housings in uranium mines, therefore they are ideal for all artificial wells.

Pipelines for the transport of water and central heating, sewerage and other fluids in city supply

Depending on the specific characteristics of the polymer used, it is possible to lay the piping for cold and hot water, as well as for sewage under pressure. The use of various polymers allows the pipeline to be inexpensive in maintenance and durable, which is more cost effective in the conditions of the city environment of modern megalopolises.

Underground and surface layering of colored and rare metals

Due to its high resistance to any concentration of corrosive liquids, as well as ease of installation, the use of MPC can increase the safety of the transport of corrosive products and significantly reduces the risk of adverse environmental impact. The durability of the MPC enables the reuse of the pipeline after the closure of the mine.

Mining industry, hydraulic transport and pneumatic transport

High MPC resistance to wear is 4 times higher than metal pipes. Similarly, the lifetime increases and reduces maintenance costs.

Strengthening of the coast, construction of ports and ports, support for different structures. Transport of salt water, construction of pipelines in salt soil, marine infrastructure

Due to the high pipe strength and the possibility of filling the interior with concrete, MPC pipes can be used as support for different objects in conditions of corrosive external environment. A welded metal grille that gives the tubes high-strength properties is protected by polymer from all sides, therefore, when in contact with salt water, inside the pipe as well as outside, there is no oxidation process of the grid, which strength of the tube remains an unchanged parameter.

One production line with one extruder, which works in automatic mode

It allows you to create an uninterrupted and maximum automated production process to achieve and maintain a continuously high quality standard for each product series.

Dual cooling system, which prevents the formation of a rough crystal structure at the macromolecule level

It gives polyethylene more flexibility. The main pressures on the system are assumed by the steel grid, which enables the achievement of the high-strength characteristics of the whole pipe system from the MPC, many times greater than the strength of the polyethylene tubes without reinforcement.

The tube calibration system to the inner diameter, which forms a glossy inner surface with minimal roughness of the substrate

It allows to increase the flow rate in the pipeline by reducing friction on the surface and ultimately increasing the capacity of the pipeline, allowing replacement of the entire system on the pipe of a smaller diameter without loss of volume of the transported liquid.

MPC – polymer tubes reinforced with a solid steel wire welded wire. The strength of the steel structure in combination with chemical resistance and special properties of polyethylene, determine the diverse purpose of MPC in various industries, including the transport of oil and gas, acids, acid liquids, industrial water, hot and cold water. High wear resistance allows the use of MPC to transport corrosive liquids with high content of solid particles.

MPC provides:

Reliable pipeline operation during installation in wet and aggressive soil
Minimum requirements for the preparation of trenches for laying
Excludes waterproofing and electrochemical protection

For the production of MPC is used:

Polyethylene class ELTEX (manufacturer – Solvay Polyolefins Europe, Belgium)
Wire for general purpose according to GOST 3282-74, diameter 3 mm

The polyethylene used is allowed for contact with food, therefore the MPC has the necessary permits for use in the construction of a drinking water pipeline.

Metal reinforcement provides MPC with high mechanical strength and the ability to self-resilience. The brilliant interior surface and the practical absence of adhesion of materials and liquids prevent the accumulation of deposits, it provides an increase in the capacity of the pipeline by 20% compared to the metal analogue. The coefficient of linear expansion is almost equal to the same for steel tubes.

The experience of the company confirms that the use of MPC gives a significant economic effect, based on the calculation of medium and long term exploitation.

Couplings: elbows, t-joints, fittings, couplings

Along with the production of current pipes, our company produces the accompanying pipe assortment – drainage (30, 45, 60 and 90 degrees), t – joints of the same diameter and fittings.

Assembly

 

Metal pipes of our production, unlike metal pipes, do not require protection against corrosion and cathodic protection, which significantly reduces time and economic costs. Due to the fact that the weight per meter of our pipe is about 1/3 of weight per meter of steel pipe, there is no need to use special equipment for installation and installation of pipelines. This has a significant economic effect.

Quality installation ensures the durability and announced technical characteristics of the pipeline. The installation of a pipeline produced by our branch of LLC “Sever-Stroj” meets all the technical requirements and RD when installing the pipe. The basic method of connecting the pipe during installation is the interconnection of the pipe, where the quality of the weld is of great importance. For the installation of pipes, Sever-Stroj has all the necessary technical equipment and specially trained personnel, which enables the installation of a pipeline.

MEPOS was founded in 1990 in Yekaterinburg city by a prestigious team of engineers, the authors of the technology of production of plastic pipes reinforced with steel gratings, with incredibly high characteristics. The development of this technology is caused by the need to reduce the cost of using expensive titanium tubes and stainless steel tubes when laying uranium. At the same time, there was a need to maintain high exploitation characteristics. The task the designers faced was more than ambitious, because the new product should have been:

  • Strong enough to be used as a bore hole
  • Resistant to aggressive environments
  • Longevity
  • Easy to install
  • Significantly cheaper in the production of steel and titanium analogs

The result was the creation of a unique metalloplastic tube that has been used by the company of the USSR Middle Machinery Industry in 1977, in uranium mines in the Leninbad region of Uzbekistan, at a depth of 800 m.

In 1979, in the immediate vicinity of these uranium mines, an earthquake amplitude of more than 9 degrees Richter scale occurred. All wells, in which metalloplastics pipes were used, did not suffer serious damage and even retained the internal geometric shape.

Thanks to high exploitation characteristics, metalloplastics pipes are used in other areas of industry and housing – transport of oil, gas, alkaline fluids, acids, water and other liquids.

The company’s priority was always the quality of production. For this reason, MEPOS pipes can be used for decades, as documented by our partners.

Up to this point, Mepos has built several thousand kilometers of pipelines, and among the biggest clients are Gazprom, Lukoyl, Rosneft and TNK-BR.
