- Mar 19, 2018 -

3PE anti-corrosion steel pipe base metal includes seamless steel pipe, spiral steel pipe and straight seam steel pipe, three-layer polyethylene (3PE) anti-corrosion coating with good corrosion resistance, water vapor permeability and mechanical properties, etc. The industry has been widely used. An anti-corrosion coating for 3PE anticorrosive steel pipes is of vital importance to the life of buried pipelines. Pipes of the same material, some buried in the ground for decades, do not corrode, and some have leaked for several years because they have been used differently. The outer coating.
