Parameter

Jiangsu Sheye Metal is a manufacturer specialized in manufacturing polished stainless steel pipes.

This tube includes mechanically polished cleaning tube and bright annealing cleaning tube. The tubes need to be mechanical polished.

Mechanical polishing can be divided into three steps: Coarse Grinding, Fine Grinding, QC of external surface(Visual exam of inner pipe, appearance inspection, roughness, roundness, outside diameter thickness). Then degreasing is necessary.

Degreasing also includes three steps, namely degreasing, passivation, RO water rinse. After another inspection, all tubes can be packed and ready for shipment.

We can polish a wide range of polished stainless steel pipe in diameter 4.0mm to 1219mm. And the wall thickness ranges from 0.5mm to 100mm. For metal, we are serious.
