Vacuum Insulated Pipe
Flexible VIP
FLEXIBLE VACUUM INSULATED PIPE
Flexible VIP is an indispensable tool for the safe, efficient, and economical transfer of cryogenic liquids. Compared with rigid VIP, it has good bending ability and can meet the installation requirements of various site conditions. Our flexible VIP has applications in laboratory, industrial, instrumentation or fueling.
