The HDPE Pipe provided by the company.
The connection method of hdpe pipe can be divided into three steps, as follows:
(1) Before the socket, first check whether the specifications of the rubber sealing ring are consistent with the matching products, intact and elastic. The rubber sealing ring should be installed in the groove between the first and second wave crests of the socket. The sealing ring must be straightened out for bottling, and its installation quantity should be determined according to relevant design requirements. If two sealing rings need to be installed, they can be placed in a corrugated space.
(2) When connecting, first clean the wall of the socket of the hdpe double-wall corrugated pipe, and apply lubricant on the wall of the socket and the rubber ring of the socket of the HDPE corrugated pipe, and then align the center axis of the end face of the socket.
(3) The interface method should be carried out according to the following procedure: For DN400 and below pipelines, one person uses a cotton rope to hang the socket of the installed HDPE double-wall corrugated pipe, and the other person uses a long crowbar to insert the foundation diagonally and hold it against the double wall. The horizontal baffle at the center of the end of the corrugated pipe, and then slowly insert the PE corrugated pipe into the socket of the HDPE double-wall corrugated pipe to be installed to the predetermined position; the PE pipe above DN400 can be pulled by two hand hoists. Bit. When the interface is closed, the lever hoists on both sides of the pipe section should be pulled synchronously to make the rubber seal ring correctly in place without twisting or falling off.
The connection method of HDPE double-wall corrugated pipe adopts the socket connection method: the rubber ring is placed in the first or second groove of the pipe socket, and lubricant is applied to the inner wall of the socket and the rubber ring of the socket before insertion. The socket has at least four grooves inserted into the socket.
