Update:2020-12-23 View(s):543 Keywords :The difference between galvanized steel pipe and stainless steel pipe
1. The meaning of galvanized steel pipe and stainless steel pipe is different
Galvanized steel pipe, welded steel pipe with hot-dip galvanized or electro-galvanized layer on the surface.
Stainless steel pipe is a hollow long round steel.
2. Different application scope
Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, and other manufacturing industries.
Stainless steel pipes are widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation, and other industrial pipelines and mechanical structural parts. Also, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also often used as furniture and kitchen utensils.
3. Different production methods
The manufacturing method of the black pipe (furnace welding or electric welding) is selected by the manufacturer. Hot-dip galvanizing is used for galvanizing.
