Description
The paper will present a complete methodology for designing a support system for process pipes in cryogenic multi-channel vacuum insulated transfer lines on the example of a BayonetCan module dedicated to the PIP II accelerator infrastructure at FermiLab. The process of constructing fixed and sliding supports, in particular supports dedicated to cooperation with compensation bellows, will be discussed. The paper defines the scope of requirements for supports in accordance with EN 13480, ISO EN 21009 and EN 14917 standards. It also presents a comparison of these requirements with those of equivalent American standards such as ASME B31.3 and ASME BPVC. Load definition, selection of materials and optimization of the structure in mechanical and thermal terms. The discussed supports were analyzed using the finite element method, the paper will present the results of thermal analysis in the form of temperature profiles and heat inputs as well as mechanical properties such as stiffness, buckling strength and stress values.
