High - prec. cold - rolled alloy tubes, precise

Cold rolled alloy tubes are cylindrical metal products that undergo a specific manufacturing process to enhance their mechanical properties. The term "cold rolled" refers to the method of shaping the metal at room temperature, which allows for tighter tolerances and improved surface finishes compared to hot rolled alternatives. The process involves taking a metal alloy, typically steel, and passing it through rollers to achieve the desired dimensions and properties without the application of heat.

Production process

.Raw material preparation:
Select appropriate alloy steel billet, usually round or square steel, and ensure its chemical composition and physical properties meet the requirements.
.Heating:
Heating the billet to an appropriate temperature to improve its plasticity for the subsequent rolling process.
.Cold rolling:
The heated billet is cold rolled through a cold rolling mill, gradually reducing its diameter and increasing its length. During the cold rolling process, the material is deformed at room temperature, which can increase its strength and hardness.
.Annealing treatment:
After cold rolling, the pipe may have internal stress and high hardness, so annealing is required to eliminate internal stress and improve the plasticity and toughness of the pipe.
.Pickling:
Remove scale, rust and impurities from the pipe surface by pickling to improve surface finish and adhesion.
.Surface treatment:
According to customer needs, corresponding surface treatment is carried out, such as phosphating, electroplating, sandblasting, etc., to improve corrosion resistance and aesthetics.
.Cutting and finished product inspection:
Cut the cold rolled alloy tubes into required lengths and inspect them in terms of size, appearance, performance, etc. to ensure that the products meet the standards.
.Packaging and Shipping:
Qualified cold rolled alloy tubes are packed and ready to be shipped to customers.
