How to repair chloride ion corrosion leakage points in stainless steel seamless elbows?

2025,7, 5

The necessary steps for repairing chloride ion corrosion leakage points in stainless steel seamless elbows are threefold:
① Polish the leakage point until the metal color is exposed;
② Apply specialized chloride ion anti-corrosion coating (such as KNM22 type) to block corrosion;
③ The outer layer is wrapped and welded with 316L material sleeves.
Do not directly repair welding without anti-corrosion measures, otherwise it will accelerate secondary corrosion.

What is the situation where the size of stainless steel seamless elbows becomes unstable after cold drawing?
