Easy installation, resistance to compressive and corrosion forces, light weight and reduction of purchase and installation costs of double-walled polyethylene fittings and durability and long service life of this type of fittings have made this type of fittings welcome in sewerage projects. The variety of double-walled polyethylene connections, the development of the water supply network has accelerated the implementation of sewerage projects and increased the quality of its implementation.

Carogit pipes are usually used in the transfer of sewage and fluids that are transferred by gravity and fluid transfer is designed without internal pressure. Due to the fact that corrugated pipes do not have internal load pressure, it means that the fluid passing through these pipes does not have internal load pressure, and these pipes are practically responsible for transferring liquid fluids as an underground atmosphere. Usually, this type of pipe has a maximum They can withstand internal pressure of . times. This type of pipe is offered in two types with couplers and without couplers. The size of corrugated pipes is available in the non-coupler type from to mm and in the coupler type from to mm.

For example, it can be said that mm polyurethane sewage polyethylene pipe has a ring resistance of . kN and double-walled polyethylene corrugated pipe with a size of mm has a ring resistance of , . and kg. Is Newton. It is interesting to know that pipes with dimensions of mm and above have only a ring pressure of . kN and are thus designed only for installation in larger projects.

The price of polyethylene pipes and fittings has a lot to do with the price of raw materials and the desired size as well as the diameter of the pipe. The price of raw materials is also announced by petrochemical companies in the stock market, and competition also arises on the base price, and the final price of raw materials is sold higher than the base price. In the price list of polyethylene pipes and fittings, the price of polyethylene pipes is easily calculated because the consumption of raw materials for each meter of pipe is known, and the costs of transportation and overhead and production costs are added as a percentage and the final price is determined.
