Steel belt reinforced polyethylene (HDPE) spiral corrugated pipe is a kind of structural wall pipe with HDPE and steel tape fusion composite. The wall structure is composed of three layers: the inner layer is a continuous solid wall inner layer pipe and the inner pipe is wound and compounded outside. The steel belt is folded into a U-shaped annular corrugated steel strip reinforcement, and the composite corrugated steel strip reinforcement is compounded with the same outer layer of HDPE as the steel strip reinforcement. The new structure is scientific and reasonable.
