Polyethylene pipe (HDPE) in Russia are widely used because of its durability and ease of installation and largely replaced the metal pipe. hdpe pipes are now used in various fields, not only for water and sanitation, they also serve for gas and up to the fishery. The pipes is performed by different methods of welding. There are various types of welding machines (Weltech, kew, etc.). But in our article focuses on a novelty in the Russian market of plastic pipes – the pipes fks. Krah GmbH company developed the technology of spiral pipes in particular for the production of large diameter pipes. Also solved the problem connection of these pipes by using Flare connecting established by electro-fusion welding. Ductwork fks solved the problem of sewage systems for many subsequent generations, together with this successful applied in many other areas, ensuring durability and efficiency of facilities such as: marine collector manholes and pipes, drainage systems, industrial tanks and storage tanks for chemicals materials, ventilation systems, wastewater treatment plants, drainage systems for areas with storage of solid wastes, storage of methane gas, etc.
fks pipes made of various properties of a diameter up to 4.000 mm and Depending on the specification, fks pipes are made of high density polyethylene (HDPE) or polypropylene (PP). fks pipes connected by Spigot connections established with the help of electro-fusion welding, optional the customer is possible to produce pipes for cushioning, fittings or socket weld. With the help of fks is possible to create all types of storage tanks, manholes and other facilities for special purposes diameter up to 3.600 mm. Thanks to the hygienic production of pipes fks, the use of high-density polyethylene (HDPE), pipes are successfully used for transport and storage products. Production of the inner surface of pipes fks bright colors with retro-reflection property of coextrusion technology further provides advantages in visual inspection, the inner surface of the channel for video. fks Pipes can be made with specially coated for coextrusion technology, which promotes the release of static electricity in critical projects.
Pipes fks, together with ensuring wastelessness during transportation and storage due to its high resistance to shock, have the possibility of storage of the telescopic tube method (nested), which in turn provides space savings in transportation and storage. With the ability to connect pipes fks electro-fusion welding, pipe fks offer advantages in the production of trenches for pipe-laying – requires a narrow trench, the minimum expenditure of time and effort laying. fks pipes are guaranteed to retain the original qualities of at least 50 years. Pipes, capable of serving up to 100 years, have a manufacturer's warranty for 50 years. Characteristic features of hdpe pipe provides high resistance to the effects of fks seismic movements of the soil, mechanical effects of rodents, the root system of plants, and corrosive liquids. Pipes fks, made from polyethylene (HDPE) having stabilizer property to uv rays, have high stability of the sun. Along with this, this feature helps to reduce sensitivity to temperature changes. Thanks to the smooth inner surface of the inner surfaces of pipes fks provided high rate of passage of waste water, together with that is not conducive to the formation of sludge. Due to its high resistance to chemicals of the pipe is not subject to corrosion and has a high degree of resistance
