Galvanized Steel Pipe Manufacturers China

Galvanized steel pipe is divided into cold galvanized steel pipe and hot galvanized steel pipe. Cold galvanized steel pipe has been banned, and the latter is also temporarily promoted by the state.

In the 1960s and 1970s, developed countries began to develop new types of pipes and banned galvanized pipes.

Hot-dip galvanized steel pipes are widely used in fire protection, electric power and highway.

Hot dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery.

Welded steel pipe with hot dip or electrogalvanized layer on the surface of galvanized steel pipe.

Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life.

Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, oil, etc., they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters and condensation in chemical coking equipment. Pipes for coolers, coal distillation oil washing exchangers, trestle pipe piles, support pipes for mine tunnels, etc.

The hot-dip galvanized pipe reacts the molten metal with the iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer.

Hot dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, wash through the ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then send into Hot dip plating bath. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
