Do You Know The Classification Of The Steel Pipes?

galvanized steel pipe is not only used to transport fluids and powdered solids, heat exchange, manufacture of mechanical parts and containers, but also an economical steel. Steel pipe manufacturing structure of the grid, pillars and mechanical brackets, can reduce the weight, save 20-40% of metal, but also achieve the mechanization of factory construction. Using steel pipe to make road bridges not only saves steel, simplifies construction, but also greatly reduces the area of painted protective layer, saving investment and maintenance costs.

Classification according to coating characteristics 

Steel coated by the surface features can be divided into: black tube (not coated) and coated tube.

Pre Galvanized steel pipes coating pipe, aluminum pipe, chrome pipe, aluminum pipe and other alloy layer of steel pipe.

Coating tube with coating tube inside and outside.

Commonly used coatings are plastic, epoxy resin, coal tar epoxy resin and a variety of glass-type anti-corrosion coating. Galvanized pipe is divided into KBG pipe, JDG pipe, threaded pipe and so on.
