Products Description
Bright tube surface quality Bright tube, outer surface clean, no oxide layer, no cracks, folding, rolling, scarring, separation, hair lines. The bright tube has an internal and external surface state corresponding to the manufacturing method and heat treatment method used (such as scratches, bumps, grooves), but its depth does not exceed 0.02mm.
Due to the limitation of brighten annealed steel strip, the wall thickness of Brighten Steel square/rectangular pipe made from this material should be below 2.0mm.

Production
Cold drawn or cold rolled refined bright steel pipe, production range: Outer diameter: 3.0-60mm wall thickness: 0.5-8mm.
The main raw materials are St35, St37.4(10#), St45(20#), St55(35#), St52(16Mn), CK45, etc. Steel pipe can be cold bending deformation at any Angle, flaring, flattening without cracks, suitable for various bending deformation of steel pipe processing industries.
Bright tube delivery length: usually 6 meters, (other delivery length as request)
Principle
After the final cold forming of the steel, a heat treatment to eliminate internal stress is carried out, and the steel pipe can be properly reprocessed within a certain limit. After the final cold forming, the steel pipe is annealed in a non-oxidizing medium protective gas. After the final cold forming, the steel pipe is annealed in the non-oxidizing medium protective gas above the upper phase change point
application
Bright pipe is a kind of steel pipe with excellent mechanical process performance and can withstand high pressure, especially suitable for hydraulic machinery and auto parts air conditioning refrigeration industry.
