HDPE spiral-wound structural wall pipe (Kela pipe) is a new type of specially shaped structural wall pipe made from high-density polyethylene through a hot-winding process. It features a high-density polyethylene structure wall formed by hot winding.
Steel wire mesh-reinforced polyethylene composite pipe is a new type of pipe material that uses a high-strength steel wire mesh skeleton, formed by helical winding on both the left and right sides, as its reinforcing element. The base material is high-density polyethylene (HDPE), and a high-performance HDPE-modified adhesive resin is used to tightly bond the steel wire skeleton with the inner and outer layers of HDPE.
