China Big Supplier of Sn4 Sn8 HDPE Double Wall Corrugated Pipe for Construction Industry, Find details about China HDPE Pipe, Underground Pipe from Big Supplier of Sn4 Sn8 HDPE Double Wall Corrugated Pipe for Construction Industry
Strong resistance to external pressure The outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil loads. In this performance, HDPE double-arm corrugated pipe has obvious advantages compared with other pipes. |
Low temperature and impact resistance The embrittlement temperature of HDPE double-wall corrugated pipe is -70ºC. Under normal low temperature conditions (above -30ºC), special protective measures are not necessary for construction. The HDPE double-wall pipe makes it convenient in winter. |
Convenient construction As the HDPE double-wall corrugated pipe is light in weight, it is convenient to carry and connect, so the construction is convenient and the work is simple. |
