The key issue in answering this question is what edition of API 607 do you want to comply with, or compare to BS 6755 part 2 (Fire test)? Both standards cover test. What industry codes and standards are used for leak testing of valves? What is the difference between BS 6755 Part 1 and BS 6755 Part 2? There are lots of standards but the design always begins with the pressure class you want the valve to be.īS 86 Testing of valves - Specification for production pressure testing requirements. Ranges,Confirm your medium's min to max.temperature then you can get the line pressure for your valve.Go back to API 598 and see the shell test rating(it will be 1.5 times the rated pressure)and seat test pressure(it will be 1.1 times the rated pressure). There are many:- API(AMERICAN PETROLEUM INSTITUTE)598,MSS SP68,AWWA C-504,ANSI B16.34(IT GIVES THE TEMPERATURE VS PRESSURE RATING) NOW, For eg:- you have a butterfly valve of 300 pressure class then how will you get the pressure rating,shell test pressure,seat test pressure? You first confirm that the valve's pressure testing is as per API 598.Then go to ANSI B16.34 300# class to check the pressure rating for the particular material(body and disc).
