The inner rib reinforced polyethylene (PE) spiral corrugated pipe is the newly developed all-plastic reinforced winding pipe currently on the market. This pipe is made of high density polyethylene (HDPE) and has high corrosion resistance. The outer surface area of the pipe is large, and the soil is formed into a common pressure with the soil. The inner rib structure ensures the ring stiffness requirement of the pipe. The pipe specification is DN200-1200mm, and the pipe length is 6m, 9m and 12m.
The corrugated structure of the pipe is reasonable, which is conducive to expanding the contact surface with the soil. The backfill filled in the trough of the pipeline and the pipeline itself together withstand the surrounding soil pressure, forming a joint effect of the pipe and the soil.
The upright inner rib in the middle of the pipe corrugation greatly improves the stability of the wave crest and enhances the pipe's disturbance pressure and impact resistance.
The width of the welded surface of the plastic strip is large and the effect is good, so that the tensile strength of the joint of the pipe is high.
The pipe connection adopts the socket rubber ring and the socket electric hot-melt connection to ensure zero leakage and the stainless steel clamp type connection is convenient and reliable.
