Corrugated pipeusedforsewageand daily waste piping inpublic facilities,residential area,farmland,chemical plants. FEATURES: Pressure: S1 4KN/SQM, S2 8KN/SQM Length: no longer than 12M Color ·Entire black, outside black with blue insideandother colors on request the outer wall of the special channels, a closed wave, in the course of processing the material by high temperature extrusion out, in a dedicated forming die and mold, the heated internal and external layer of material in peak separation and integration within the trough as a whole, in the mold by vacuum forming, and cooling means.HDPE double-wall corrugated pipe properties ·The ring-like ripple structure, has the mechanical properties which has both hard and softly comes finely, surrounds the rigidity to be high, the flexibility is good ·Pipe wall smooth, fluid friction is small, the input flow of large ·The midheaven structure, the weight is light, the transportation, the construction are convenient, the operating charges are low ·Connect easily, the joint sealing is good, reliable quality and long-term operation, no leakage ·Chemically stable, corrosion-resistant, non-toxic non-polluting, an environmentally-friendly equipment ·Bears the low temperature, the resistance to wear is good, buries above the service life 50 years ·Suitable circles the curvature, but does not need the fitting to lay down directly the tubing in Yu Luewan the trough ·Total cost than the steel pipe is low, life (50 years), the use of cost only reinforced pipe 30 40% ·Green environmental protection.
