How to address saltwater penetration in stainless steel pipe welds
Thread Content
Saline solution (containing NACL and a small amount of NA2CO3) keeps seeping out from the welds of the stainless steel pipes; the temperature of this saline solution is around 80–90 degrees. Thank you

First, verify whether there are any issues with the stainless steel material being used, as saltwater is highly corrosive at this temperature. Additionally, the welding process must be strictly followed. Since leakage has occurred, if it is not due to corrosion-induced perforations, then there are cracks present. The formation of welding cracks is mentioned in various stainless steel welding procedure manuals, which can be referred to for further information.
