3 Inch Diameter Galvanized Steel Pipe High Strength Roll Forming ERW Welded

 

Galvanized Steel Pipe, ERW Tubes, black or galvanized, 1/2“~8”

 

 

 

 

ERW welding round pipesalso are called as Electric Resistance

 

Welded Pipes.This type of steel pipes and tubes are widely used in

 

various fields such as engineering purposes, fencing, scaffolding, line

 

pipes etc. ERW steel pipes and tube are available in various qualities, wall

 

thicknesses, and diameters of the finished pipes.

 

While manufacturing ERW steel pipes, there are some strictly standard:

 

high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-

 

carbon steel. High performance ERW steel pipes and tubing possess high

 

strength corrosion resistance, high deformability, high strength and high

 

toughness.

 

• ERW welding steel pipe is available with square ends or beveled for

 

welding, threaded and coupled and victaulic grooved.

 

• Surface finish are available in black or bare, or with protective coatings.

 

 

 

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

 

 

The detailed size is as following:
