FIELD: transportation.
SUBSTANCE: cryogenic pipeline is intended for transportation of liquefied gases and can be used in gas processing and gas-chemical industries. It is made of coaxially installed internal 1 and external 2 pipes, vacuum space 3 between which are divided into sections. Pipeline is supplemented with side walls, temperature compensator 4, internal supports 5, made of super-insulating material, and basket 6 with adsorbing agent, which are fixed between internal 1 and external 2 pipes, and vacuum valve 7 and safety valve 8.
EFFECT: reduced level of mechanical stresses occurring in pipeline design due to temperature difference of its separate elements, and provision of its operation in conditions of emergency situations both at insignificant and significant depressurisation.
