What is Pre galvanized round steel pipe?

The pre-galvanizedwelded 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.

The per-galvanized welded pipes are widely used in heat,water,and natural gas supply systems,agricultural greenhouse construction,steel structureconstruction,as well as low and medium pressure piping system.

Which Specification of pre galvanized round pipe can we offer?

This pre galvanized steel pipeshall 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 weldbead 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.

RAW Materials-Hot dipped galvanized steel strips:

The zinc coatingon 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.

Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. 2 inch hot dipped galvanized tube, fence erw galvanized steel pipe, construction steel pipe gi pipe is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.2 inch hot dipped galvanized tube, fence erw galvanized steel pipe, construction steel pipe gi pipe is covered with a zinc material to make the steel pipe more resistant to corrosion.
