PROBLEM TO BE SOLVED: To provide a method of installing a heat shielding material in the vicinity of a service pipe that is located in a gas turbine support material and includes radial inner and outer mounting members.SOLUTION: A service pipe assembly for a support material 82 of a gas turbine engine, includes: a service pipe 96 including a radial outer mounting member 88 and a radial inner mounting member 90; and a heat shielding material 94 extending from the radial outer mounting member 88 toward the radial inner mounting member 90. The heat shielding material 94 is fixed to the radial outer mounting member 88. A device and method are provided for lowering an operation temperature of the gas turbine engine exposed to the service pipe assembly by using a skirt 98 and the radial outer mounting member 88. When exposure to a temperature is reduced, a temperature of the service pipe assembly is minimized during an operation of the engine so as to prevent oil from being converted into coke or varnish.SELECTED DRAWING: Figure 3 【課題】ガスタービン用支材内に位置し、半径方向内側、外側取り付け部材とを含む供給管付近に遮熱材を設置する方法を提供する。【解決手段】ガスタービンエンジンの支材８２用の供給管組立体は、半径方向外側取り付け部材８８と半径方向内側取り付け部材９０とを含む供給管９６と、前記半径方向外側取り付け部材８８から前記半径方向内側取り付け部材９０に向けて延びた遮熱材９４と、を備え、前記遮熱材９４が、前記半径方向外側取り付け部材８８に固定される。スカート９８と半径方向外側搭載部９０とを使用することにより、供給管組立体に対して露出されたガスタービンエンジンの動作温度を下げる装置および方法。温度への露出を減らすと、エンジン動作中、供給管組立体の温度が最小化して、油のコークス化またはワニス化が発生しにくくなる。【選択図】図３
