The article presents numerical methods of modelling cryogenic pipelines with vacuum insulation. A single-channel nitrogen line with vacuum insulation and an applied U-type natural compensation was selected as the test object. The calculations were performed using both CAEPIPE and Ansys software. All possible variants of the model's construction were analysed. The obtained results were compared, and the possible causes of discrepancies in the obtained results were defined.
