Production Process
The production process of black steel pipe: strip steel is pickled to remove impurities. The strip steel is continuously rolled to the required thickness, and the strip steel is softened by an annealing process, which is convenient for further welding to make a black annealed steel pipe.
Features of black pipe
1. The same as solid steel, the tensile and torsional resistance is slightly high, but the weight is light.
2. Bending without cracking and flaring without opening
3. For the use of lightweight vehicle parts, it can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing time.
Application
Black-backed steel pipes are widely used in construction, tables, chairs, hangers, iron beds and other furniture, interior decoration, bicycles, lightweight vehicles, etc.
