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.

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 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:
