What material is used for anti-corrosion
Pipeline anti-corrosion materials are divided into pipeline-themed anti-corrosion materials and their corresponding mending materials. The main body anti-corrosion mainly includes petroleum pitch, epoxy coal pitch, anti-corrosion cold-wrapped tape, epoxy powder, PE coating, and PP coating.
Commonly used mending methods include petroleum asphalt mending, epoxy coal tar mending, anti-corrosive cold-wrapped tape, epoxy powder mending, and PE heat shrinkable material mending.
If the main body of the pipeline is a three-layer PE composite structure, the joint material is three-layer PE heats shrinkable joint material.
The patch of single-layer epoxy powder coating can adopt three methods: epoxy powder, primer + anti-corrosive cold-wrapped tape, and PE heat-shrink patch.
