CRYOGENIC PIPELINE

摘要

FIELD: cryogenic engineering. ^ SUBSTANCE: invention can be used for making of pipelines for transportation of cryogenic liquids at pressure. Invention makes it possible to reduce service expenses owing to provision of pneumatic tests of cryogenic pipelines operating under pressure with use of acoustic emission without opening external sealed housing. According to invention acoustic transparent insert is built into one more heat insulating supports separating inner pipe and sealed housing of cryogenic pipeline to provide acoustic contact between inner pipe and outer housing. ^ EFFECT: improved safety. ^ 1 dwg
