Fluid transfer seal assemblies for transferring process fluid between a stationary component and a rotating component, fluid transfer systems, and methods for transferring process fluid between the stationary and rotating components via a fluid transfer assembly are provided. A rotatable component includes a sealing surface. The fluid transfer seal assembly comprises a face seal ring having at least one segment of a fluid passageway and a sealing face configured to be disposed opposite of the sealing surface. The sealing face or the opposed sealing surface includes a geometric feature for forming a hydrodynamic seal therebetween. A secondary seal is configured to be disposed between and contacting the face seal ring and the stationary component.

Fluid transfer seal assemblies, fluid transfer systems, and methods for transferring process fluid between stationary and rotating components using the same

Thermal isolating service tubes and assemblies thereof for gas turbine engines are provided. The thermal isolating service tube comprises an inner tubular member defining a fluid passage and at least one outer tubular member disposed about the inner tubular member. A spacing volume is defined between at least the inner tubular member and an adjacent outer tubular member. The thermal isolating service tube comprises a unitary structure and has at least one portion with a curved configuration, a non-circular cross-sectional shape, or both.
