Seamless Steel Pipe: Anti-corrosion Process
The raw material of seamless steel pipe is iron, which easy to rusty and will affect the service life. Therefore, anti-corrosion is a process that must be done before pipeline construction. 3pe anti-corrosion or epoxy coal tar pitch is two methods that mainly used for seamless steel pipe. The following is an precaution introduction for seamless steel pipe anti-corrosion.
Seamless steel pipe anti-corrosion process
1. The anti-corrosion of the steel pipe is in accordance with the requirements of the drawings, using epoxy coal tar paint outsourcing the glass cloth, and the outer coating is anti-corrosion painting.
2. The outer wall construction process: pipeline derusting → primer coating → first pass top coat → second pass top coat → wrap glass cloth → top coat → top coat;
3. Inner wall construction process: pipeline derusting → primer coating → first pass top coat → second pass top coat → third pass top coat
