Product Introduction：
HDPE double wall corrugated pipe is a hollow structure wall pipe with smooth inner wall and circular corrugated outer wall. It is made of HDPE as raw material and co extruded by double machines in one molding process. It is a flexible buried drainage pipe suitable for municipal rainwater and sewage, building sewage and communication sheath scenarios. The ring stiffness is SN4-SN16, with a service life of more than 50 years, widely replacing concrete/cast iron pipes.
