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).

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.

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.
