HDPE double-wall corrugated pipe
HDPE double-wall corrugated pipe has the characteristics of good corrosion resistance, high insulation, smooth inner wall and low flow resistance of ordinary plastic pipes. It also adopts a special double-layer hollow ring structure, has excellent ring stiffness, good strength and toughness, light weight, strong impact resistance and is not easy to break. Polyethylene (HDPE) double-wall corrugated pipe for buried drainage is modified with high-density polyethylene resin as raw material and appropriate amount of additives, manufactured by extrusion molding process. It is widely used in municipal drainage, sewage pipeline system and sewage and drainage pipeline system outside buildings, sewage treatment plant pipeline system, airport, wharf, high-grade highway drainage pipeline system, chemical industry, mining and other industries for special fluid transportation and discharge pipeline system.
