There are three types of pipe connections for PE pipes:

First, the hot melt butt joint: the heating plate of a certain temperature is heated at the opposite ends (the pipe and the pipe or the pipe and the pipe) for a certain period of time, the heating plate is removed, and the two ends to be welded are quickly docked under a certain pressure. Together, until the interface cools down, such an interface with a higher strength than the pipe matrix is ​​formed.

The second is the hot-melt socket connection: the two welded parts are heated by the same heating plate with a special heating plate with a film. After the inner surface reaches the specified temperature, the outer surface heating element is inserted into the inner surface heating element to cool. After generating a new interface.

The third is the electrofusion connection: the tube itself has an electronic heating element, and when the heating element passes the control current for a certain period of time, the connection portion of the tube tube is melted. This results in a strong, permanent, airtight and reliable interface. The ductile iron pipe adopts a rubber ring seal socket connection, which is relatively simple. If there is a pipe with a pressure of more than 16 kg, consider using a flange connection.

The service life of PE pipes is determined by various factors, such as raw materials, production processes, usage methods, and environment of PE pipes. The construction of the PE pipe will also have a certain impact on the damage or friction of the pipe itself. The damage of the pipe itself will reduce the service life of the pipe. Although the PE pipe can be used for corrosion protection, it will have a great impact on the service life in a particularly harsh environment.
