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.

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.

Double-walled polyethylene pipes or corrugated pipes as you can see in the picture above are called pipes that have two walls, one outer with a wavy appearance or in other words, a ring and an inner layer of the pipe that has a smooth surface that Fluids with acidic and alkaline wastewater and industrial effluents are used. Carogite pipes also have an outer surface which is ring-shaped and has high strength and all surface and subsurface pressures, both live and dead load in They are borne under the ground and the reason for this loop is the curling of the pipe surface due to the strengthening of the pipe. Due to the location of this type of pipe in the dug canals and trenches and the possibility of traffic load on this type of pipes, they are designed in a way that has the ability to bear the weight of soil on the canal and traffic load on it at the same time. . Therefore, these types of pipes have the ability to withstand very high external pressure. Carogit pipes are classified into three compression sections (meaning pressure, external load pressure), which are - / - kN, respectively, each of which has a specific consumption in terms of soil surface type, surface and subsurface load pressure. Today, we see corrugated pipes in this way in our world and in everyday life in the streets and alleys with a yellow interior and a black cross section.

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.
