The difference between plastic-coated steel pipe and epoxy-coated composite steel pipe inside and ou

epoxy resin composite steel pipe is a steel-plastic composite product with a steel pipe as the base pipe, plastic powder as the coating material, and a plastic layer or other anti-corrosion layers on the inner and outer surfaces of the steel pipe. plastic-coated steel pipes are divided into polyethylene-coated steel pipes and epoxy-coated steel pipes according to the inner coating material. the product mark consists of the code of the plastic-coated composite steel pipe, the code of the inner coating material, and the nominal size.

plastic-coated steel pipes are also called plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes. they are mainly based on steel pipes, and a layer of plastic anti-corrosion is welded on the inner surface of steel pipes (bottom pipes) through spraying, rolling, dipping, and suction processes. layers of composite steel pipes with plastic anti-corrosion layers welded on the inner and outer surfaces. plastic-coated steel pipe has very strong corrosion resistance and relatively small frictional resistance. epoxy resin-coated steel pipe, also known as pe composite steel pipe, is mainly suitable for the transportation of water supply and drainage, seawater, warm water, oil, gas, and other media.
