ADVANTAGES OF HONED TUBE

1, High precision tolerances;
Our honed steel tube can meet ID tolerance H7,  H8,  H9, … etc according to the customer’ requirements, and its I.D dimension.

2, Seamless tube with high pressure resistance;
We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications.

3, High Smooth inside surface;
The roughness of our honed pipe is Max Ra 0.4 microns ID finish .

4, Good weld ability: The weld ability of our honed steel tubing is very good, this is quite helpful for manufacturing the cylinders.
