Where did u get shell & seat pressure from code(API 598/Api 6d) please mention me the page number

[@WeldingNDTInspection]

Valve Shell Test Pressure The API STD 598 refers you to the table 3 in the standard and provides the test pressure for cast iron valves based on their ratings but you know the majority of the industrial valves are made from cast steel. For cast steel, the API 598 refers you to the ASME B16.34 for test pressure. The ASME B16.34 indicates that the shell test shall not be less than 1.5 times the 38°C (100°F) pressure rating, rounded off to the next higher 1 bar (25 psi) increment. For example, if you have a valve with cast steel material (A 216 Gr. WCB) and rating of 2500, you should refer to the table 2.1.1 in ASME B16.34. The table says your working pressure is 425.5 bar at 38°C (100°F). It equals to the 6524.85 psi. Now multiply this value by 1.5 and your test pressure will be 9382.3 psi. You have to round it to the next 25 psi, and it will be 9400 PSI. Valve Shell Test Duration On both API STD 598 and ASME B16.34 shell test duration depends on the valve size. The valve size less or equal 2 inch the test duration will be 15 seconds, between 2 1/2 and 6 inch 60 seconds, between 8 and 12 inch 120 seconds and above 14 inch will be 300 seconds.
