Steel Tube Factory Announced Cold-Rolled Seamless Pipe (GB3639-2000) Information
Cold-rolled seamless pipes (GB3639-2000) are precision steel tubes manufactured through cold drawing or cold rolling processes. These pipes are widely used in mechanical structures, hydraulic systems, and other applications that require high dimensional accuracy and excellent surface finish. They are known for their superior quality and reliability compared to standard rolled pipes.
This type of seamless steel pipe includes various categories such as carbon steel thin-walled pipes, alloy thin-wall steel pipes, general steel pipes, low and medium pressure boiler tubes, high-pressure boiler tubes, alloy steel pipes, stainless steel pipes, oil cracking tubes, and special-shaped steel pipes. Each type is designed for specific industrial needs, ensuring optimal performance under different operating conditions.
Compared to hot-rolled seamless pipes, which typically have an outer diameter greater than 32mm and wall thickness ranging from 2.5mm to 75mm, cold-rolled seamless pipes can achieve much smaller dimensions. For example, the diameter can be as small as 6mm, with a wall thickness as thin as 0.25mm. Thin-walled pipes may even have an outer diameter of 5mm and a wall thickness less than 0.25mm. This makes them ideal for applications where space is limited and precision is critical.
One of the key advantages of cold-rolling is its ability to produce pipes with higher dimensional accuracy and better surface finish. The process also enhances the mechanical properties of the material, making the final product more durable and suitable for high-performance applications.
Whether you're looking for standard or specialized steel tubes, the cold-rolled seamless pipe (GB3639-2000) offers a versatile and reliable solution for a wide range of industries, including automotive, aerospace, construction, and manufacturing.
