Compared with general steel pipes, the outer-circle and inner-shaped steel pipes have a certain degree of increase in cost, but in the process of application, it can bring us more convenience.
In terms of the two characteristics of no leakage and cold bending without changing the shape, the quality requirements of most general steel pipes are all impossible to reach. Therefore, we can often see the excellent performance of precision outer and inner special-shaped steel pipes in those industrial parts that require very high steel pipe materials for hydraulic components.
use:
Used in the manufacture of mechanical structures, hydraulic equipment, auto parts, steel sleeves.
Common materials:
10#, 20#, 35#, 45#, 20cr, 40Cr, 20CrMo, 16mn, 27simn, 304, 201, 310s, high-quality carbon structural steel.
Features of precision outer circle and inner special-shaped steel pipe:
1. The outer diameter is smaller.
2. High precision can be used for small batch production.
3. The cold-drawn finished product has high precision and good surface quality.
4. The horizontal area of the steel pipe is more complicated.
5. The performance of the steel pipe is superior, and the metal is denser.
