Our Precision Steel Tube

ld drawn pipe, cold rolled pipe

After pickling, phosphating, our seamless pipe can do deep work such as cold drawn, or cold rolled.

This process can change the size of OD, ID, WT and the mechanical property of the carbon tube.

Roughness: ra1.6-3.2 

Straightness: 1:1000mm

2.honed tube,SRB tube

A:  IDHoned

Utilize an abrasive stone,which turns while being moved in and out of the work piece.

The honing process makes :
1)Smooth surface finishes inside bores
2)Hold precise tolerances on bore diameters 

ID H8 H9 H10
ID roughness 0.4-0.8μm

B:  ID Skiving and roller burnishing

Two thin chips are cut at high feed rate while the tool passes through the workpiece,

producing mirror inner,with a bore precise tolerance .

ID H8 H9 H10
ID roughness 0.2-0.8μm
ID max 250mm
