CryoWorks uses stainless steel inner and outer pipes and/or flex hoses in the manufacturing of its Vacuum Insulated Piping Systems.  The piping consists of a factory fabricated inner line and an outer jacket.  The inner line carries the cryogenic fluid while a vacuum space between the inner and outer provides the insulation and low heat gain.   The vacuum annular space consists of a multi-layer superinsulation, internal gettering material and an extremely low vacuum level of 9 microns or less. 

BENEFITS:

• 50 times more effective than conventional foam in preventing heat gain to the inner line.
• Extremely long lasting
• Built to ANSI B.31.3 Code for Pressure Piping

JOINTS: 

Each system consists of multiple spool sections that are joined together in the field with a male and female bayonet joint (or optional welded field joint).

Each spool section must be carefully designed to allow for transportation to your site and installation at the facility.

• A Bayonet is a mechanical joint (close-tolerance male and female bayonets with o-ring seal and clamp) for ease of assembly and disassembly in the field. 
• The Welded Field Joint is a vacuum insulated assembly that couples two spools together via a field welded sleeve.
