Unless specifically requested, all raw materials are from Yongxing Special Steel. After each process, the materials and identification cards are checked for consistency, and then the inspection is carried out one by one to ensure that the raw materials are qualified and then production begins.

The production process is complete, ensuring that more than 100 control points in many links such as raw materials, cold processing, heat treatment, cleaning, polishing, passivation, and electropolishing won’t be ignored.

The inspection of finished stainless steel tubes is carried out in strict accordance with the standard or contract agreement, and the original inspection records are kept for one year.
