We obtain this coating through the insertion of the high density polyethylene tube in the inner surface of the pipe. Its high resistance to the chemical attacks and its width prevent the wearing caused by the erosion, friction and/or corrosion in the production and injection well pipes, it also poses a low percentage of hydrolysis damage, high mechanical adherence and low rugosity, witch favors the diminution of incrustations and paraffin deposition.

PE80 Outer sheathing of polyethylene

The external polyethylene works as a barrier to isolate the steel pipe from the different soil types. Its width (4 mm) and tenacity give it enough mechanical resistance to endure hits and other mechanical actions of the pipe manipulation, in addition to the high anti-corrosive resistance proper of the high density polyethylene. The application system allows the appliance on pipes with different inner coatings.
