制作流程 (2)Precautions in the use of anticorrosive steel tubes

3PE anticorrosive steel pipe, national standard 3PE anticorrosive steel pipeThe pipe end of this anticorrosive coating is prone to warping due to corrosion.According to the analysis, when grinding the groove of polyethylene layer in the reserved section of 3PE anticorrosive steel pipe, the remaining height of the welding seam at the end of the pipe is not polished or polished unevenly, which will lead to the epoxy powder at the bottom of the polyethylene protruding part of the welding seam being ground by anticorrosive steel pipe factory and thermal insulation steel pipe factory

National standard 3PE anticorrosive steel pipe during the use of matters needing attention, anticorrosive steel pipe factory, thermal insulation steel pipe factory three-layer structure polyethylene (3PE) anticorrosive coating with its good corrosion resistance, water and gas permeability and mechanical properties, etc., in the oil pipeline industry has been widely used.
