Ammonia pressure relief

Ammonia pressure relief

Ammonia pressure relief

(OP)
We have @ 30 pressure relief valves connected to a header that leads to a diffuser water tank. The piping and header is galvanized steel pipe .The diffuser tank is stainless steel.We have had some relief valves release causing the galvanize to wash off.Will this weaken the pipe or cause the valves to deteriorate ? What would be the effect on the SS diffuser tank? It is turning white inside. Should we replace the pipe before changing relief valves?
