As a new type of holed material, pre-stress double wall corrugated pipe has many advantages compared with metallic corrugated pipe. It is acid resistant, alkali resistant, it has good sealing property, there is no seepage for water or paste, its rigidity is rather high. Its frictional coefficient is small. It is convenient for connection in construction. So it has overcome all shortcomings of traditional metallic corrugated pipes. Such kind of pipes is originally imported from overseas with rather high price and long time delivery. Facing such status, Co. Has positively absorbed and introduced technique of foreign equipment and depended on relative research institutes and developed production line for chiefly HDPE UPVC pre-stress double wall corrugated pipe, the specification ranges from 50-160 mm. This item has filled national gap. This will undoubtedly facilitate application of pre-stress double wall corrugated pipe. It will also bring a lot of profit for producers of relative finished products.
