Quality Cryogenics offers two types of Vacuum Insulated connections depending on the design conditions and installation requirements.

Bayonet Connections are designed for lower pressure applications up to 150 psig. Bayonet connections do not require any welding or vacuum work in the field. If the piping is measured correctly, bayonets offer an easy to install, low profile, vacuum insulated connection.

Field Joint Connections offer improved thermal efficiency over bayonets but require a skilled field service team and specialized vacuum equipment for installation. Field joints are designed to handle higher pressure applications and offer increase structural durability due to the all SS welded construction. In addition, Quality Cryogenics Field Joints allow for some field adjustments during the install.
