Cold Drawn Welded Steel Tube Product Process
Cold drawing is a method of cold working steel pipes through molds, which can significantly improve the accuracy and strength of the pipe. In the cold drawing process, the diameter and wall thickness of the steel pipe are gradually reduced by the mold under the action of tensile force, and its internal structure and mechanical properties are improved at the same time.
Bright annealing is a heat treatment process carried out in a protective atmosphere to eliminate the stresses generated during cold working and restore the plasticity and toughness of the material while maintaining its shiny surface. This process helps to further improve the corrosion resistance and aesthetics of the tube.
After bright annealing, the surface of the tube will be finely polished to achieve a mirror effect. Polishing not only improves the appearance quality of the tube, but also removes microscopic defects and scratches on the surface, enhancing its surface finish and corrosion resistance.
Excellent corrosion resistance: 304L stainless steel has excellent corrosion resistance, which can resist the erosion of a variety of corrosive media and ensure the long-term stable operation of the pipeline system.
High strength and toughness: The cold drawing process significantly improves the strength and toughness of the pipe, which can withstand higher working pressures and harsher working environments.
High precision and smooth surface: Bright annealing and polishing treatment make the tube have extremely high dimensional accuracy and smooth surface quality, reduce fluid resistance, and improve conveying efficiency.
Good processing performance: This pipe is easy to cut, bend and weld and other processing operations, which is convenient for on-site construction and installation.
ASTM A312 304L Bright Annealing Polishing Cold Drawn Steel Pipe has been widely used in several fields due to its superior performance and beautiful appearance:
used to transport oil, natural gas and other corrosive fluids to ensure the safety and reliability of pipeline systems.
Playing an important role in media conveying systems that require high purity and corrosion resistance.
