Pre-Galvanizing Pipe

Pre-Galvanizing Pipe is galvanizing, the amount of galvanizing is very small, only 10-50g/m2, its corrosion resistance is much different than that of hot galvanizing pipe. Pre-galvanized steel pipe is the treatment of steel pipe before galvanizing: degreasing treatment, derusting treatment, phosphating treatment, drying treatment.

Introduction:

Pre-Galvanizing Pipe is galvanizing, the amount of galvanizing is very small, only 10-50g/m2, its corrosion resistance is much different than that of hot galvanizing pipe. Zinc layer is an electroplating layer, and zinc layer is separately stratified with the steel tube matrix. The zinc layer is thin, and the zinc layer simply adheres to the steel tube matrix, which is easy to fall off. Therefore, its corrosion resistance is poor.
Pre-galvanized steel pipe is the treatment of steel pipe before galvanizing: degreasing treatment, derusting treatment, phosphating treatment, drying treatment.
