HDPE Corrugated Spiral Pipes which is described as the world''s best drainage pipes wit Larger Diameters of Corrugated pipes are three layers which supports each other and it standard is DIN 16961. With all the features shared by all commercially available plastic tube, and both the resistance and the metal reinforcement is slightly more inside a pipe.
Because the “n” factor will remain more constant over than the “n” factor of competing pipe raw materials, Downsizing with CPP’S Smooth Core n-10 on flat grades can be possible. Using smaller size CPP pipes at steeper grades to achieve higher flow rates is also possible because HDPE raw material based pipes are more abrasion resistant than competing raw material based pipes.
