HDPE spiral wound structural wall type A pipe

HDPE Ductile Iron Alternative In buried engineering projects such as municipal drainage and sewage systems, the compressive strength, settlement resistance, and sealing performance of pipe materials are the three key factors determining the long-term reliability of the system. Traditional rigid pipes are prone to breakage and leakage under uneven foundation settlement, while ordinary plastic pipes often lack sufficient ring stiffness under large-diameter conditions. This HDPE Double Wall Corrugated Pipe was developed to address this issue. Its inner and outer walls are smooth, connected by square spiral ribs, forming a unique structural wall design, falling into the category of flexible pipes. The product has good ductility, excellent compressive strength and uneven settlement resistance, effectively adapting to complex geological conditions such as foundation deformation and earthquakes, improving the earthquake resistance and disaster reduction capabilities of public utilities.
