描述

TPP anticorrosive steel pipe is called: externally wound polyethylene inner melted epoxy anticorrosive pipeline.Name interpretation: externally wound polyethylene refers to the pipeline outer wall to do 3E anticorrosive treatment, a total of three layers, one layer of epoxy powder, one layer of adhesives, the last layer of polyethylene winding.Internally melted epoxy refers to the pipeline inner wall to do epoxy tree {qin} resin powder anticorrosive treatment, refers to The epoxy resin powder was coated on the pipe by high temperature melting process. The product solved the problem that the outer monolayer polyethylene was applied to the pipe. At the same time, the inner wall anticorrosion standard reached the food grade.
