Claim 0:
1. A monolithic metal thermal insulating sleeve liner configured for use in a high pressure fluid flow device subjected to cyclic extreme thermal shock, said configured thermal insulating sleeve liner comprising:
a monolithic hollow metal cylindrical sleeve having two opposing spaced-apart ends and an outer diameter sized to slide into a bore of a fluid flow device, said ends being fused so as to seal against fluid flow between an inner surface of the fluid flow device bore and the outer diameter of the sleeve between said ends, while accommodating a fluid flow path there-within along an inside bore of said sleeve, said sleeve including internal interstices providing increased thermal resistance to heat flowing from inside the sleeve to outside the sleeve;
said monolithic hollow metal cylindrical sleeve comprising outer and inner shells integrally formed with tessellated support structures arrayed there-between.
