PIPELINE ATTACHMENT FITTING ASSEMBLY ON BODY OF TURBOMACHINE Russian patent published in 2019 - IPC F16L3/12 F02C7/20 

FIELD: valve production.

SUBSTANCE: invention relates to the design of pipeline attachment fitting assemblies in mechanical engineering, mainly in turbo-mechanical engineering. Pipeline attachment fitting assembly on the turbomachine body contains a clamp covering the pipeline section and secured by means of fixation to the turbomachine body, wherein the clamp is provided with at least two flanges with through holes for fixing means, a gasket installed between the clamp and the covered section of the pipeline. In addition, the pipeline attachment fitting assembly is provided with an even number of flat stiffeners connecting the clamp with the flanges in pairs. Axis of the through holes is located between the corresponding pair of stiffeners, and the clamp, flanges and stiffeners are made of composite material reinforced with polyimide or aramid fibers.

EFFECT: invention provides a reduction in mass while maintaining the required rigidity and strength and, as a consequence, ensuring the resource and reliability of the pipeline attachment fitting assembly on the turbomachine body as a whole, including in the operating conditions at high temperatures, that is, at temperatures close to the upper temperature limits of the permissible performance of the materials used.
