EASY-FIT HEAT SCREENING DEVICE FOR CONNECTING A COOLING PIPE AND A THROUGH-HOLE FORMED IN A NOZZLE SUPPORT RING OF A GAS TURBINE

摘要

An easy-fit heat screening device (110) for connecting a cooling pipe (112) and a through-hole (114) formed in a nozzle support ring (116) of a gas turbine, of the type comprising a tubular structure (118) which has an external diameter smaller than a diameter of the through-hole (114) and into which the cooling pipe (112) extends; this tubular structure (118) has at the top a shaped annular end (126) which is inserted inside a groove (130) formed in the through-hole (114).
