Cryogenic Bayonet B3000 Series

Cryogenic Bayonet for Vacuum Insulated Piping Systems

Cryocomp bayonet assemblies offer low heat leak and quick solution field installation. Our B3000 Cryogenic Bayonet series is a high-efficiency tube & pipe connection for vacuum-jacketed transfer lines and vacuum insulated piping systems. The assemblies range from 1/2" tube to 1" pipe with a 150 PSI MAWP. The design utilizes an extremely close tolerance fit between the male and female components establishing a gas pocket (vapor lock) between the components to form a seal, which is at process stream temperature at one end and ambient at the other. The very small gas pocket and thin stainless elements contribute
to the high-efficiency of the design. The close tolerance design eliminates the necessity of a nose seal. Other advantages are frost-free transfers, minimization of heat leak and easy disassembly. The pipe product line connects with a clamping system for continuous leak-free operation. Bayonet assemblies offer savings in terms of decreasing field assembly time and lower installation costs coinciding with low heat leak.

The B3000 bayonet series will operate efficiently in the vertical position (male on top) or horizontal position and is recommended for atmospheric gases. Specify Cryocomp B3000 bayonets on your next vacuum insulated piping job.

For each size bayonet there is a male and a female piece. For each male/female bayonet there is required a V band and an O-ring. To order the complete set (male, female, V-band and O-Ring, use "SB" after the dash, for example: B3049-SB.
