Zinc Coated Tube - China

Galvanized Steel Pipe

What is hot dipped galvanized steel pipe?

Zinc coated tube is one of our main pruduct, as a leading Zinc coated tube manufacturer in China, we can give you a factory price!

Hot-dip galvanizing (HDG), as referenced in the process of dipping fabricated steel into a kettle or vat of molten zinc.

While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.

What is pre galvanized (GI) round steel pipe?

The pre-galvanized welded steel pipe refers to welded tube which undergoes decreasing, rust removal, phosphorization, and 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 What is ERW welded round steel pipe?

Welding pipes is one of the simplest and most durable ways to join piping together and steel pipes can simply be welded together with MIG (metal inert gas), TIG (tungsten inert gas or SMAW (stick metal arc) welding.

Before welding two pipes together, avoid any gaps between the two pipes.

While welding, take measures to ensure the continual alignment of the two pipes.
