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 devicecan have a tubular memberhaving at least one locusof non-uniform outside dimension and an axial flow passagewith a uniform inside diameter between opposite end connection elements. A thermal sleeve linercan be disposed about the axial flow passage in a boreformed in the tubular member, wherein the sleeve comprises an outer surface having a thermal barrier coating. A pressure-relief passageis 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.
