Hot-dip galvanizing (HDG), as referenced is 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.

Product Description

What is welded galvanized square steel pipe?

Hot-dip galvanizing (HDG), as referenced is 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.

The pre-galvanized welded steel piperefers 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

Product Detailed

Brief Introduction

Galvanized steel pipe are also called Galvanized Steel tube and Gi pipe. It possess features of corrosion resistance,
anti-rust,acid resistance, which extend its service life largely. Galvanized steel pipe is widely used in many area:
water pipe, gas pipe, oil and other generally low pressure fluid pipeline, and is also used in petroleum industry
especially the marine oil field oil well pipe, oil pipe, chemical coking equipment oil heater, cooler,
coal run oil exchanger tubes, mine tunnel support rack pipe etc.
