VIP Connections

Vacuum Insulated Pipe (VIP) Bayonet Connections

There are many options when it comes to connections for Vacuum Insulated Piping Systems. The most popular and most efficient options are vacuum insulated field can joints and bayonet connections (also known as a Johnston Couplings). CryoWorks offers a Close Tolerance (CT), F-Series, Linde CB7 Helium and HQK Hydrogen bayonet options. These connections must be placed strategically to allow for transportation and installation at your facility.

Bayonet Connection

A bayonet connection consists of a male and female connector that can easily be installed without any field welding or unique training. The tight-fitting male and female bayonet design provides a long heat path from the outer jacket to the inner pipe. This creates a low heat leak connection. CryoWorks offers close tolerance fit bayonets as well as dissimilar metal tip bayonet types. Our bayonet connections also 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.

Ideal For: Inert Gases

F-Series (Flange) Bayonet Connection

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.

Ideal for: LH2, LN2, LOX, and LNG

Linde CB7 Series

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.

Vacuum Insulated 

Field Can Joint

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.
