Vacuum insulated double wall pipe consists of an inner tube and an outer tube. The vacuum chamber between the inner and outer tubes can reduce the input of external heat during the transferof the cryogenic liquid, and the outer tube provides a secondary barrier to prevent the leakage of LNG.
Super vacuum insulation technology to minimize medium heat leakage.
● Built in corrugated expansion joint to effectively compensate for displacement compensation due to working temperature.
● Factory prefabrication and on-site assembly mode improves product performance and shortens installation period.
● It can meet the product certification requirements of DNV, CCS, ABS and other classification societies.
5 × 10-2Pa
