PE pipe is more and more extensive, and the construction personnel need to pay more attention to the connection quality of PE pipe to ensure the reliable and stable operation of the pipe network. The connection between

flanged PE pipe and other metal pipes The bolts on the flange plate of

are fixed with metal pipes such as flanged PE pipes, which is not only convenient to operate, but also short in construction period. Flange connections are mainly used to connect PE pipes to metal pipes or valves, flow meters, pressure gauges and other auxiliary equipment. Flange connection is mainly composed of PE injection flange, steel or aluminum flange, gasket or sealing ring, bolt and nut. Flange connection is the process of tightening bolts and nuts from beginning to end, so that the flange joint is in close contact with the flange parts. PE pipes can be connected to other metal pipes.

Flange connection method between PE pipe and valve fittings

1. According to the flange connection requirements, weld an injection flange at the end of the PE pipe to be connected;

2. Insert another steel flange into the end of the flexible metal pipe to be connected to the valve;

3. According to the connection requirements of PE pipes, connect the flat end of the injection flange joint (along the pipe end) to the PE pipe by hot melting or electric melting;

4. Put the flange gasket or sealing ring into the steel flange between the metal pipe end and the flange connection end surface (heel pipe end), so that the connection surface is tightly matched;

5. the installation bolts and tighten them evenly in symmetrical positions.
