Inner Rib Reinforced Corrugated Pipe is a newly developed all plastic inner rib reinforced winding pipe in the market. This pipe is made of high density polyethylene (HDPE) as raw material. The pipe has a large surface area, forming the same compressive strength of pipe soil. The welding effect is good and the tensile strength of the joint is enhanced. The inner rib structure is conducive to improve the stability of ring stiffness. At present, domestic manufacturers can produce DN200 ~ 3000mm pipes of various specifications, and the production length of pipes is 6m, 9m and 12m.
