I'm looking for some thoughts on Material Qualification of Fire-tested Valves according to ISO 10497:2010 and API 607 7th Edition.
We have tested 2" & 6" ANSI 150/600/1500 in Carbon Steel to Qualify 1/2" - 12" ANSI 150-1500. We are now looking at Testing Stainless and Duplex to complete the Range, initially we were looking at testing a Mid Range Valve (4") 150, 600 and 1500 in each material. But note that API says to 'a single valve of each material' so we are now considering testing a 4" 600 of each material to qualify the full tange in Feritic, Stainless, Ni Alloy (Qualified by Stainless) and Duplex SS.
Any thoughts or experience on this subject would be appreciated. For Reference we are testing Side-Entry Trunnion and Top-Entry Trunnion in both Soft and Metal Seated.
