Vacuum Insulated Pipe (VIP) Bayonet Connections

Our Close Tolerance (CT) bayonet connections have a low-profile flange to simplify installation allowing pipes to slide through hangers and supports easily. This low profile also decreases core hole diameters and required sealant.

The F-Series bayonet connections are high efficiency cryogenic couplings designed for vacuum insulated piping systems. CryoWorks has developed a proprietary treating process that provides long-term dimensional stability and allows for a closer tolerance fit that provides best in class thermal performance.

The Linde CB7 series bayonet is designed for Liquid Helium applications, but is also used in nitrogen, oxygen (with proper cleaning and seal material) and argon. Available in four thermal lengths: 3″ to interchange with existing Linde installations, 6″, 9″, and 15″ to fit most thermal and physical criteria.

The Linde HQK bayonet connection consists of a male and female connector that can be easily installed without any field welding or unique training. With its’ noseseal design, the HQK bayonet is ideal for hydrogen filling applications for connections on Trailer Hoses, Tankers, and Transport Vessels.

Vacuum Insulated Field Can Joints are used in place of bayonet connections when the pressure ratings of the piping system exceed that of standard bayonet connections as well as in larger bore piping systems when bayonets are not cost effective or available. CryoWorks can also accommodate vacuum insulated field can joints at tees, elbows, and valves. Installation can be completed by any certified welder trained in cryogenic and vacuum installations.
