For on-site stainless steel storage tanks, when there is no deionized water available for the hydrostatic testing and the chloride ion concentration exceeds 25 ppm, what is the usual approach to deal with this situation?

See 150.4-2024 11.4.2.1 for details

If there is truly no water that meets the standards, it can be used temporarily to complete the pressure washing; after that, the area should be drained and cleaned thoroughly before rinsing it with deionized water using a high-pressure water gun. Make sure to rinse thoroughly. In this way, only a small amount of deionized water is needed, so it should be easy to obtain

I didn’t notice any new statements regarding the standards; I studied * it
