Cryogenic transfer pipelines are an important part of cryogenic systems, used to transport cryogenic fluids to different terminals. Cryogenic transfer pipelines use vacuum multi-layer insulation to reduce heat leakage and are mainly composed of an outer pipe, vacuum jacket, multi-layer insulation wrapping, insulation supports, expansion joints, and radiation shields. Depending on the amount of cryogenic fluid being transported, they can be single-channel or multi-channel cryogenic transfer pipelines. According to the rigidity of the pipeline, they can be divided into rigid or flexible pipes.
