One of the important applications of corrugated pipes is their use in power cable transmission system. In power pipelines, the working pressure is approximately equal to kN / m. These pipes have other applications such as construction of manholes, sewage treatment tanks, pipes for transferring water to the sea and rivers, etc. Of course, to make this equipment, Carogit pipes with a very large diameter are needed.

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.

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.
