Abstract:
1. A facility for working, using at least one jet of fluid at cryogenic temperature under high pressure, comprising: a) at least one mobile tool having one or more nozzles for distributing cryogenic fluid, and b) one or more fluid pipes adapted and designed to carry fluid at cryogenic temperature to said mobile tool in order to supply at least one fluid distribution nozzle of said mobile tool with fluid at cryogenic temperature under high pressure, at least one part of the fluid pipe or pipes comprising insulating means for the thermal insulation of said at least one part of the pipes, wherein the insulating means comprise: c) at least one chamber placed around all or part of said at least one pipe or part of a pipe to be insulated, d) at least one source of insulating gas, and e) insulating gas supply means establishing fluid communication between said at least one insulating gas source and the inside of said at least one chamber, so as to supply said at least one chamber with insulating gas from said at least one insulating gas source, thereby forming an insulating gaseous atmosphere within said at least one chamber, wherein the insulating gas source comprises the exhaust device of at least one heat exchanger, the insulating gas supply means being in fluid communication with said exhaust device in such a way that at least part of the gas escaping through said exhaust device can be recovered, conveyed and subsequently introduced into at least one chamber placed around part or all of said at least one pipe or part of a pipe to be insulated.
