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.

Usually, the lifetime of Carrogate pipes is estimated to be , and even years, which depends on the raw materials, production conditions, storage and maintenance of the pipe. Note that in cases where the pipe must be buried and withstand environmental conditions, there are things that must be considered when installing the pipe. In relation to Carrogate pipes, soil pH should be taken into consideration. Carrogate pipes produced from polyethylene have been used for about half a century due to the impossibility of settling, rotting, easy installation and resistance to soil movement and pressure. The technical specifications and quality of Carrogate double-walled pipe must comply with the standard DIN- (related to the control of pipe dimensions and annular strength) and EN (other tests related to product quality specifications).

Carogit pipes are produced in different sizes in the form of Carogit pipes and Carogit spiral pipes, which in fact only the production method is different in that in the production of Carogit pipes, polyethylene material is molded and pressed in one piece, but in the production of pipes. Spiral carogit production method is very different. In this method, the profiles or the protrusions on the pipe are cooled by the extruder that produces the pipe profiles after cooling and passing through the water inside the tub, and it is gradually rolled in a spiral and glued together by a series of interactions. After gluing the inner layer of the tube, which is yellow, it sits on the inner wall of the tube and on the profiles and is glued on the tube by defined high pressure pulleys. These pipes are usually produced in high sizes, ie from to . The sizes of corrugated and spiral corrugated pipes are:
