How to connect PE water supply pipes?
Author:
PE (polyethylene) materials are widely used in the field of water supply pipe manufacturing due to their high strength, corrosion resistance, and non-toxicity. Therefore, PE water supply pipes are quickly utilized, and since the pipes are in sections, they must be connected to be longer. How are PE water supply pipes connected? Below are some methods for connecting PE water supply pipes for your reference.
How to connect PE water supply pipes?
There are many connection methods between polyethylene pipes and pipes, pipes and PE pipes, pipes and fittings, as well as between polyethylene pipes and metal pipes. Each connection method has its own advantages and limitations. Users can choose the appropriate connection method based on factors such as pipe diameter, working pressure, and usage environment. Common connection methods for urban water supply polyethylene pipelines include: heat fusion connection, electric fusion connection, socket-type flexible connection, flange connection, and steel-plastic transition joint connection.
Connection method for PE water supply pipes: heat fusion connection
How to connect PE water supply pipes? A common method is to use heat. Heat fusion connection involves using specialized heating tools to heat the connection area of the polyethylene pipe or fitting under pressure until it melts. After removing the heating tool, pressure is applied to join the two melted surfaces together, maintaining stable pressure for a period until the joint cools. Heat fusion connections include butt fusion, socket fusion, and saddle fusion.
Connection method for PE water supply pipes: electric fusion connection
Secondly, how to connect PE water supply pipes is mostly based on the principle of heat. Simply put, electric fusion connection is this principle. Electric fusion connection involves using specialized electric fusion fittings with embedded resistance wires that make close contact with the connection area of the PE pipe or fitting. The PE pipe is heated at the connection area through the embedded resistance wire until it melts and fuses into one, until the joint cools. Electric fusion connections can be used to connect polyethylene pipes or fittings of different types and different melt flow rates. Electric fusion connections are divided into socket electric fusion connections and saddle electric fusion connections.
