Patent ID: 8783279

Claim:
A tubular fluid flow device of varying outside dimensions for use in a rapidly cycling temperature environment, comprising: a tubular member ( 10 ) having at least one locus of non-uniform outside dimension ( 14 , 16 ) and an axial flow passage ( 20 ) with a uniform inside diameter between opposite end connection elements ( 16 ); a thermal sleeve liner ( 22 ) disposed about the axial flow passage in a bore ( 24 ) formed in the tubular member; a thermal barrier coating ( 26 ) disposed on an exterior surface of the thermal sleeve liner ( 22 ) located at an interface between and in direct contact with the exterior surface of the thermal sleeve liner and an inner surface of the bore; and a pressure-relief passage ( 28 ) in fluid communication with the interface between the exterior surface of the thermal sleeve liner and the inner surface of the bore.
