Galvanized pipe is galvanized on the inner and outer surfaces of the steel pipe to prevent corrosion of the surrounding environment and increase the service life.

Galvanized pipes can be galvanized seamless steel pipes or welded steel pipes, and different galvanizing methods have different effects on the service life of steel pipes.

Now the galvanized pipes on the market are welded steel pipe galvanized, galvanized with pipe.

Galvanized welded pipe is a welded pipe processed by hot-dip galvanizing. Requirements for zinc layer: According to Article 6.2 of GB/T13912-2002 "Technical requirements and test methods for hot-dip galvanized layer of metal-clad steel products", for the wall thickness ≥ 6mm For pipes, the average thickness of the coating is 85μm; for pipes with 3mm<wall thickness<6mm, the average thickness of the coating is 70μm.

Galvanized strip pipe is galvanized strip, which is made of galvanized pipe after bending, welding and other processing. The difference between it and galvanized welded pipe is that the cost is low and the corresponding service life is short.

Galvanized pipes are widely used. The natural gas pipelines in our daily life are galvanized welded pipes. Galvanized pipes are also used in heating and greenhouse construction. Some shelf pipes used in construction are also galvanized pipes for anti-corrosion.
