Abstract
A tubular fluid flow device of varying outside dimensions adapted for use in a high pressure, rapidly cycling temperature environment, an isolation ball valve, a ball valve isolation method and a catalyst transfer method. The flow device 10 can have a tubular member 12 having at least one locus 14, 16 of non-uniform outside dimension and an axial flow passage 20 with a uniform inside diameter between opposite end connection elements. A thermal sleeve liner 22 can be disposed about the axial flow passage in a bore 24 formed in the tubular member, wherein the sleeve comprises an outer surface having a thermal barrier coating 26. A pressure-relief passage 28 is provided in fluid communication between the axial flow passage and an interface between an exterior surface of the thermal sleeve liner and an inner surface of the bore.
