Could someone please tell me what are the common approval/certifications you get for acid valves used in a petrochemical plant?
I have been told our customer is looking for a UAV approval?????
The closest acid-related approval that sort of matches your question is the UOP approved manufacturer list for HF acid (hydrofluoric acid) service at alkylation plants.
Please let me know if you need any assistance on locating valves for alkylation service; these are generally carbon steel body/monel trim or monel/monel valves, and only a handful of vendors are approved for the demanding HF acid service conditions.
