PVC Coupling connected to plastic pipe SWD-DF06

Due to the limitations of the site and transport vehicles, many plastic pipes are usually 5.8 meters in length. To achieve this, need PVC Coupling pipes, Plastic pipes usually use two joining methods.

1.One is to use PVC  coupling to bond the tubing to the ends of the fitting by glue, which is often referred to as a cold joint. The advantage is that the operation is quick and convenient. The downside is that if the connection is not good, a leak will occur. The materials used for cold joining are usually UPVC, CPVC, PP.

2. The second method is to use a hot melt device to heat the pipes and fittings in the mold to the melting point so that they can fuse together and then cool. This method is often referred to as a hot connection. The advantage is that the connection is more sealed. The disadvantage is that the operation is cumbersome and requires special machines and molds. Usually, the pipe of this joining method is PPR, HDPE.
