A composite pipe inner support sheet metal part

Abstract

The invention belongs to a composite pipeline and pipeline supporting structure and concretely relates to composite pipeline inside support sheet metal member comprising an external side round ring. Supporting members arranged in a hexagonal shape are disposed in the external side round ring; the external side round ring is provided with an opening; and a half-moon-shaped opening structure is fixed corresponding to the opening. The composite pipeline inside support sheet metal member is advantageous in that a plurality of absorption areas for inner pipe deformation are formed due to the special half-moon-shaped opening structure; with cooperation of the hexagonal arrangement on the whole, pipeline deformation demands under composite load conditions such as heat and earthquakes can be guaranteed and shape deformation of the pipeline can be effectively absorbed; demands for inner pipeline spacing and structural strength can be well met; and installation and maintenance process of complicated composite pipeline systems can be greatly simplified.

Description

technical field [0001] The invention belongs to a composite pipeline and a pipeline support structure, in particular to an internal support sheet metal part of the composite pipeline. Background technique [0002] The gas feeding system is one of the components of the International Thermonuclear Experimental Reactor (ITER). The gas supply and collection pipeline is a major part of the gas feeding system, which is responsible for transporting the required gas from the gas source factory to the designated gas valve box. The gas supply collection pipeline is mainly composed of six gas delivery pipes with different diameters (transmitting different gases respectively), a central emptying pipe and an external containment pipe. [0003] Traditional pipe supports can only meet the support needs of general single-layer pipes, and most of them are mainly in the form of external supports. There are few inner supports available for composite pipes. In recent years, with the development...
