By using tetrafluoroethylene (PTFE), a material with excellent chemical stability, as the lining and combining it with the molding process, the steel-lined PTFE molded pipes have excellent performance in corrosion resistance and high temperature resistance. The existing steel-lined PTFE pipes do not have a lifting function, and it is difficult to adjust the height of the steel-lined PTFE molded pipes so that they can be matched with adjacent steel-lined PTFE molded pipes.
