Details:

 

processing method: cold roll forming with ERW welding

 

material: Low carbon hot rolled coils

 

steel grade: Q235B~345B

 

surface treatment: hot dip galvanizing

 

Application: liquid transmission and all kinds of steel structure purpose.

 

 

 

 

Galvanized steel pipe produce:

 

Hot dip galvanized steel pipe with pickling, first to remove iron oxide on the surface of

 

the steel tube, after acid cleaning, by ammonium chloride or zinc chloride or ammonium

 

chloride and zinc chloride mixed aqueous solution tank cleaning, and then sent to the

 

hot dip plating tank. Hot dipped galvanized zinc layer thickness, coating uniformity,

 

strong adhesion, long service life, etc. Steel substrate with molten electrolyte solution in

 

complex physical and chemical reaction, the formation of corrosion resistance of the

 

structure compact zinc alloy layer. Pure zinc layer, alloy layer and steel substrate fused

 

together .erw / lsaw spiral welded steel high quality galvanized pipe prices and

 

manufacturers
