Product Listing

CYROGENIC BREAKS - 3kV BRAZE MOUNT

Cryogenic breaks are used in the transmission of cryogenic fluids to provide an electrical break in the transmission line . These breaks are suitable for service down to liquid nitrogen temperatures (-200°C). Although rated for cryogenic service, thermal gradients of 25oC per minute must be observed to preserve the life of the seal. These breaks are designed with thin metal transitions that provide flexibility at sub-zero temperatures. Cryogenic breaks can be installed by the tungsten inert gas (TIG) welding process.

Liquid breaks are used for the transmission of coolant fluids to provide an electrical break in the transmission line. Service temperature for these breaks is restricted by coolant temperature limits. Thermal gradients of 25°C per minute must also be observed with these products. These parts are rated for a maximum line pressure of 5 bar. Liquid breaks are typically installed by soldering or low-temperature brazing. Note that subsequent brazing temperatures must not exceed 700°C.
