SENPU Steel reinforced PE spiral corrugated pipe is a new type of environmentally friendly plastic pipe made of high quality materials. It has the characteristics of light weight, high ring stiffness, convenient construction and lower comprehensive cost than cast iron pipe and concrete pipe. Municipal works: used for municipal underground drainage, sewage disposal, rainwater collection, water conveyance, ventilation, etc. Compared with the ordinary double-wall bellows, the steel belt reinforced bellows are added with a steel belt design, with higher ring stiffness and better cost performance for large diameter.
