Hi Guys
Maybe you can clarify. When using ASME IX and we are requiring CVN testing. Am i right in saying we go to B31.3 where the thickness range is T/2 to T + 1/4 inch. And not the thickness range specified in ASME IX
Does anyone know according to ASME. At present i am working on the welding of the pipes in a compressor Terminal ie butt joints. In ASME we can weld group 1 to group 1 or group 1 to group 2. But surely we cannot weld say group 1 to group 8. So where is does the limits end.Or is it we can weld...
