[0002] Composite steel pipes are pipes based on a composite structure of metal and thermoplastic plastic. In terms of synthesis, they are mostly made by coating straight seam welded pipes, spiral welded pipes, or seamless steel pipes with polyethylene or epoxy resin through heating spraying or dipping.
