HDPE double-wall corrugated pipe joints should adopt socket-type joints connected by elastic sealing rubber rings, and the rubber ring joints should comply with the following regulations:
  1. Before connecting, check whether the rubber ring is in good condition, confirm the placement position of the rubber ring and the insertion depth of the HDPE double-wall corrugated pipe socket.
  2. When connecting, first clean the inner wall of the double-wall bellows socket, and apply lubricant on the inner wall of the socket and the rubber ring of the PE bellows socket, and then align the central axis of the end face of the socket.

For pipes of DN400 and below, first one person hangs the socket of the installed HDPE double-wall corrugated pipe with a cotton rope, and the other person uses a long crowbar to insert it obliquely into the foundation, and press against the transverse baffle at the center of the end of the double-wall corrugated pipe. Then slowly insert the PE corrugated pipe into the socket of the HDPE double-wall corrugated pipe to be installed to the predetermined position;

For PE pipes above DN400, two lever hoists can be used to pull the pipe joints into place. When the joints are closed, the lever hoists on both sides of the pipe joint should be pulled synchronously so that the rubber sealing ring is in place correctly without twisting or falling off.
