HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?
Before the interface, should check the rubber ring is complete, confirm the rubber ring placement and socket insertion depth.
The interface method should be carried out according to the following procedures: DN400 pipeline and below, by a man with a cotton rope hook is installed pipe socket, the other one with a long lever oblique insertion based cross baffle against the tube end of the center position, and then forced the tube slowly into after the installation of HDPE double wall corrugated pipe the pipe socket to a predetermined position; more than two sets of DN400 pipeline by hand hoist will pull in pipe section. When the interface is closed, the spanner on both sides of the pipe section shall be pulled synchronously, so that the rubber sealing ring is properly positioned and is not distorted or not falling off.
When the interface is made, the inner wall of the bearing mouth is cleaned first, and the lubricant is coated on the inner wall of the socket and the rubber ring of the socket, and then the central axis of the socket face end is aligned.
