Emergency shut-off crimp for 3/4"nps sch80 A106B pipe
(OP)
thread330-16741: Crimping Reformer Furnace Tubes
I am looking for equipment and expertise to crimp a 3/4"nps sch80 A106B pipe pressurized with stagnant water at 1200 psig and 500 degF. It is an inter-gate pressure equalizing line on a closed gate valve that has a passing body/bonnet gasket joint. I have been advised that two partial crimps with sealant injected between is recommended. Is a complete crimp without cracking not possible for this material?
