In many engineering constructions, PE pipes, PVC pipes, and PPR pipes are used at the same time. Large-diameter plastic-coated steel pipes PE pipes and PPR pipes are connected by hot melt, while PVC pipes are generally connected by glue, while PE Due to the different performance of PPR pipes, the two cannot be directly connected. What is needed if you want to connect the two?

PE pipes and PPR pipes can generally be directly connected to each other with internal teeth and external teeth, and the accessories on the market are relatively complete.

When connecting PE pipes and PVC pipes, you can consider using flange connections. If it is a drainage project, you can consider using PE socket fittings to directly connect with the PVC pipes. If the glue is good, it can also be sealed.

Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, then add a flange gasket between the two flange plates, and finally tighten the two flange plates with bolts. It is a detachable joint that is tightly integrated.

In short, PE pipes are mainly used in water supply engineering in actual construction applications. In case of pressure, internal teeth, external teeth fittings or flange connections must be used to ensure the quality of the project.
