What are the nine common uses of seamless steel tubes?

The biggest difference between seamless steel tubes and other long steel bars is that there is no seam on the periphery, and the steel tube section is hollow. Due to the different cross-sectional shapes, they are often classified as round steel pipes and heterogeneous steel pipes. Of course, in terms of actual use efficiency, of course, round steel pipes are more common. BBN introduces the common uses of nine seamless steel pipes.

1. Bearing steel pipe (YB / Z12-77): It is mainly used for manufacturing rolling bearing rings.

2. Cold drawn precision welded pipe: mainly used for bicycle pipe material.

3.Hydraulic pillar pipe: such as 27simn seamless pipe is mainly used to manufacture hydraulic pillars, lifting pillars and hydraulic oil cylinders for coal mine shafts.

4. Carbon steel seamless steel pipe for ships (GB / T5312-1999): It is mainly used for manufacturing Class 1 and 2 pressure-resistant pipes for ships.

5. Cold-rolled seamless special-shaped steel pipe (GB / T3094- 1999): It is mainly used for manufacturing general structural parts.

6. Seamless steel pipe for transporting fluids (GB / T8163--1999): mainly used for transporting pipelines. For example: central air-conditioning, cold storage, gas, fire engineering, etc.

7. Precision inner diameter seamless steel pipe for hydraulic and pneumatic cylinders (GB / T8713- 1988): It is mainly used to manufacture hydraulic and pneumatic cylinders and other pipe fittings with high internal and external surface roughness requirements and precise internal and external dimensions. For example: jacks, shock absorbers, motor housings, cylinders, injection molding machinery, etc.

8. Seamless steel pipe for structure (GB / T8162- 1999): It is mainly used for general structure and mechanical structure.
