The pre-galvanized welded steel pipe refers to welded tube which undergo degreasing,rush removal,phosphorization,zand drying processes before galvanization.

The treatments before galvanization allow the product to be conveniently plated with a zinc coating,and also ensure uniform coating thickness,strong coating adhesion,and improved corrosion resistance.

How to Produce this Pre Galvanized Round Pipe?

This pre galvanized steel pipe shall be manufactured from pre-galvanized steel conforming to ASTM A53. The coated steel shall be cold formed and welded into tube utilizing the high frequency induction welding process capable of forming a weld bead stronger than the parent metal. The outside coating damaged during welding shall be repaired by metallizing (spraying molten zinc wire). The inside weld area damaged during welding shall be left unprotected.

The zinc coating on the steel sheet shall conform to ASTM A525 Grade G60 and G120. The exterior and interior surface shall have a combined zinc weight ranging from 0.60 oz/sq ft (or 0.45 oz/sq ft each side) to 1.20 oz/sq ft (or 0.60 oz/sq ft each side). These coating weights do not apply to the inside welded area.
