The difference between PVC pipe and PE pipe

1. When the electric fusion connection is connected by the same thermoplastic pipe and a special electric fusion pipe is inserted, the electric fusion pipe is a charged electric fusion connection machine, the required heat is the electric fusion pipe embedded in the fusion by resistance wire, and the cooling pipe and the electric fusion pipe are connected as a whole.

2. When the pipes and pipe fittings made of the same thermoplastic are connected by hot melting, the special hot melting machine is used to heat the connecting part of the surface, and the connecting contact surfaces of the main materials are fused with each other and connected into a whole before cooling. The hot-melt connection includes butt type hot-melt connection, socket type hot-melt connection and electric fusion connection.

PE pipe is safe and nontoxic, and has better flexibility and impact resistance than PVC pipe. It can be used as underground gas pipeline and water pipeline. It takes a long time for chloride ions to be separated from PVC pipes. PVC pipe is not suitable for water pipe, poor impact resistance and gas pipe. But PVC pipe is low price, high hardness, affected by temperature, small expansion and contraction, commonly used in drainage pipes and rainwater pipes.
