Quick Detail:

1.Small diameter tubing DIN2391 are made using the cold drawing process. Precision tubes are made from carbon steel from quality Bao Steel,XingCheng Steel,and HuaiSteel.

2. The tubes are high precision in tolerance,excellent surface brightness,no oxidization on the outer and inner walls after heat treatment,high cleanness of inside wall.

3. No deformation after cold bending,no crack after flaring and flattening.

Description:

Synopsis of Process Routing: Quality Carbon steel — Cold Drawn — Heat Treatment Without Oxidization (NBK Status) — Nondestructive Testing— Flushing The Internal Hole With Special Equipment Under The High Pressure —Dealing With Antirust Oil On Surface — Plastic Capping On Both Ends.

The raw material we choosing:high quality Bao Steel,XingCheng Steel and HuaiSteel.Physical and chemical inspection will be made to make sure each batch is in qualified range. After piecing,each piece of tube is checked to be in permitted size deviation,this can garantee higher thickness tolerance and concentricity.
