En10305 Shock Absorber Honed Tubing Seamless Hydraulic Honed Tubes
- Stainless seamless steel pipe is a kind of long steel with hollow section and no jointsaround
- First, the thicker the wall thickness of the product, the more economical and practical it will be. The thinner the wall thickness, the higher the processing cost will be;
- Second, the process of this product determines its limited performance. Generally, the precision of seamless steel pipe is low:the wall thickness is uneven, the brightness of the inner and outer surfaces of the pipe is low, the cost of sizing is high, and there are pockmarks and black spots on the inner and outer surfaces that are difficult to remove;
- Third, its detection and shaping must be processed offline. Therefore, it embodies its advantages in high pressure, high strength
- and mechanical structure materials.
