CONNECTION NODE OF PIPELINES IN TURBOMACHINE Russian patent published in 2018 - IPC F16L3/22 F02C7/20 

FIELD: machine building.

SUBSTANCE: invention relates to the design of nodes connecting pipe fittings in mechanical engineering, mainly turbomachinery. Node connecting the pipelines of the turbomachine contains a clamp mounted on at least two pipelines and made in the form of a pair of pads with grooves for pipelines, gaskets located in the grooves between the pads and the pipeline. Through holes are made in the blocks for the means of connecting them together. Each block is provided with at least one flat stiffener, made on the outer surface and oriented in the transverse direction relative to the pipelines. Stiffener does not exceed the height of the corresponding block. Clamp and stiffeners are made of fiber-reinforced composite material. Polyimide or aramid fibers are selected as the reinforcing fiber.

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 junction assembly as a whole, including under working conditions at high temperatures.
