How to prevent corrosion of DIN St52.0 seamless steel pipe

DIN St52.0 seamless steel pipes need anti-corrosion work before they are used. How much do you know about the anti-corrosion of DIN St52.0 seamless steel pipe?

First: Why is the DIN St52.0 seamless steel pipe anticorrosive?
DIN St52.0 seamless steel pipe is a relatively high-end steel pipe, which is relatively expensive. But after all, the raw material is iron, which will rust and affect the service life in the pipeline. Therefore, the anti-corrosion of DIN St52.0 seamless steel pipe is a process that must be done before pipeline construction. For DIN St52.0 seamless steel pipe, 3PE anti-corrosion or epoxy powder asphalt corrosion protection is mainly used.

Second: the anti-corrosion process of DIN St52.0 seamless steel pipe
According to the requirements of the drawing, the anticorrosion of DIN St52.0 seamless steel pipe is coated with epoxy powder asphalt paint and coated with glass fiber cloth.

Outer wall construction process: pipeline derusting→primer coating→first topcoat→second topcoat→winding glass cloth→topcoat→topcoat;

Inner wall construction process: pipeline derusting→priming→first pass top coat→second pass top coat→third pass top coat.
