It is a tube made of high-density polyethylene body, which is hose-shaped and its inner color is usually yellow and polished. The main use of these pipes is to collect and transfer water or sewage. This double-walled corrugated pipe, which is also known as polyethylene sewer pipe, is made of polyethylene raw materials with grade EX3 – HDPE80 or HDPE80, from size 200 mm to 1000 mm, which depending on the needs of buyers in the branches of 6 and 12 meters and They are designed and produced in toroidal resistors of 31.5 kN / m2.

Carogit pipes have two outer walls with the appearance of grooved or concave grooves to strengthen the pipe against overhead soils and to bear dead and live loads from the ground. The inner wall is mostly yellow in color, which has a perfectly smooth and polished surface. It is used to transport sewage, acidic, alkaline and industrial effluents, and even to transport seawater and rivers by gravity.

The outer wall of the double-walled sewer pipe of Carogit is protected against ultraviolet rays by using anti-UV materials and is produced as a hose. This product does not tolerate internal pressure. In this way, the flow of fluid transfer inside the pipe is only gravity and can not withstand the pressure above 1.5 bar internal.

The pipes are produced as a whole coupler and are connected to each other as males and females during the execution with the help of washers.

Whenever we talk about polyethylene pipes and their specifications, we mean all their appearance and engineering features. For single-walled and double-walled polyethylene pipes, the technical specifications include the dimensions and size of the pipe and its inner and outer diameters. In addition, the nominal pressure, outlet flow, hardness and strength of the pipes, as well as the thickness of the polyethylene pipe, are among their technical specifications. One of the most important technical issues for corrugated pipes is their annular resistance. Ring resistance is a very important feature that determines how much the corrugated pipe (with a certain diameter) can withstand the working pressure along the pipeline and how successful it will be in connection and installation. In general, polyethylene pipes are produced in branches of 6 and 12 meters and with different diameters. A very important point about the size of polyethylene pipes and their use is that with increasing the outer diameter of the pipe, the flow rate of the outlet fluid from the pipe also increases; For example, a polyethylene pipe with an outlet diameter of 160 mm has an outlet flow of 30 liters per second and a polyethylene pipe with an outer diameter of 250 mm has an outlet flow of 73 liters per second.

The main manufacturers of this product line and equipment are the United States, Germany (Drusbach, Cincinnati, Eschenbach and Bauco), China and Poland. The equipment used by Qadr Double Wall Pipes Manufacturing Company in the production of polyethylene sewage corrugated pipes has been imported from Germany. Therefore, high quality along with low weight has allowed us to compete to be among the top exporters of this product in different sizes.
