As a new type of holed material, pre-stress single 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 ageing proof, electric erosion proof, it has good soft flexibility. It is convenient for connection in construction. So it has overcome all shortcomings of traditional metallic corrugated pipes. Such kind of pipes are originally imported from overseas with rather high price and long time delivery, Facing such status, we positively absorbed and introduced technique of foreign equipment and depended on relative research institutes and developed production line for chiefly HDPE pre-stress single wall corrugated pipe, the specification ranges from ø50mm-ø160mm. This item has filled national gap. This will undoubtedly facilitate application of pre-stress single wall corrugated pipe. It will also bring a lot of profit for producers of relative finished products.
