Honed tube features

1, improved the surface roughness, roughness can be basically Ra ≤ 0.08 micro.

2, correction roundness, oval can be ≤ 0.01mm.

3. improved the surface hardness, so that the deformation of the force to eliminate, improve the hardness HV ≥ 4 °

4, after processing residual stress layer, improve fatigue strength increased by 30%.

5, improved with the quality, reduce wear and tear to extend the life of parts, but the parts of the processing costs instead.

The difference between honed pipe and seamless steel pipe

1, the main feature of seamless steel pipe is welded joints, can withstand greater pressure. The product can be very rough as cast or cold parts.

2,honed tube is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.
