The ultra-high molecular weight polyethylene (UHMWPE) lined oil pipe adopts strict process technology to closely bond the liner with the steel oil pipe, forming a “pipe-in-pipe” structure. Due to the material’s high resistance to chemical corrosion and mechanical properties, it is suitable for oil well conditions with severe corrosion, abrasion, scaling, and wax deposition.
