Carrogate double-wall pipe or polyethylene pipe Carrogate is the name of a pipe that consists of two layers of polyethylene, the inner layer is completely polished and the outer layer is wavy. Subsurface carries both live and dead loads under the surface of the earth. Carrogate double-walled pipes are classified in various types of pressure parts (pressure means external load pressure), each of which has a specific use depending on the type of soil, surface and subsurface pressure. Carrogate double-walled polyethylene pipes have a high tolerance for soil volume and ring resistance, and the internal pressure of these pipes is usually or times, and these pipes cannot be used in pressurized networks. Coupler and washer or extruder welding are used to connect these Carrogate pipes. Sewage cargo pipe or double-walled polyethylene sewage pipe is one of the products of the factory producing new-style cargo gate pipes, which with its high production capacity and standard quality of Iran and Europe, is currently one of the largest double-walled polyethylene pipe production factories in the west of the country and in Currently, Karogate pipe is exported to neighboring countries and all parts of Iran.

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.

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.

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.
