China 8 Inch Drain Threadeddouble Wall Flue Pipe, Find details about China Environmental Pipes, Industrial Use Pipes from 8 Inch Drain Threadeddouble Wall Flue Pipe
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. |
