Dear ALl,
I have one case where we need ball valve flanged RF.900# Material Body & Stem A182 F22 Cl.3, Ball & Seat A182 F22 Cl.3+Stellite6 (Weldoverlay process).
Can i use above flanged valve at temperature 593DegC since ASME B16.34 Table for mtl group 1.10 restricts up to 538DegC.
Please guide...
One question came up during globe valve vendor evaluation so please guide me:
• We need 2”-150# Globe valve A216 WCB Trim#1 (13CR) BB-OS&Y RF-SERR-FCG BS EN 10204 Type-3.1
• API602 table 12 gives us the trim#1 material details
• Now we have table F1 in same code which shows trim#8 for body...
