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.

Tubular member with thermal sleeve liner

A ball valve for use in the pressure acid leaching of nickel ores is disclosed. The valve has a valve body and a ball centrally positioned in the valve body, which has a central passage rotatable in the valve body between open and closed positions. At least one seat is disposed between the ball and the valve body. The ball and seat each comprise a titanium substrate and an ultrafine or nanostructured titania coating. The titania can include from 5 to 45 volume percent of a second phase material that is immiscible with the titania and exhibits corrosion resistance.
