Welded Circle Bright Steel Tube 0.25mm - 2.5mm Thickness
Product Introduction
Welded pipes can be used for water pipes, gas pipes, heating pipes, electric wires, etc.
The use of steel pipes to manufacture steel grids, pillars and mechanical supports can reduce weight, save 20% to 40% of metal, and realize factory-oriented mechanized construction.
The use of steel pipes to manufacture highway bridges not only saves steel, simplifies the structure, but also greatly reduces the area of the protective coating, saving investment and maintenance costs.
The internal and external surface finish of the pipe should be a typical feature in the manufacturing process, and where applicable, it should also be a typical feature of heat treatment, and should be able to identify any surface defects that need to be trimmed, such as bumps, dents or shallow grooves .
