Description

Technical Field

[0002] The 3PE outer anti-corrosion layer of the steel pipe is divided into three layers. From the inside to the outside, the first layer is an epoxy resin anti-corrosion layer, the second layer is a glue adhesive, and the third layer is polyethylene (PE). Because the steel pipe needs to be welded and sealed and connected with heat shrink tape at the landfill site, in order to ensure that the heat shrink tape connection at the two pipe ends is sealed and firm, the 3PE protective layer at both ends of the steel pipe needs to be polished and cleaned with a steel brush.
