Efficient Vacuum Insulated Cryogenic Pipe Systems

Vacuum systems are much more efficient than “foam-insulated pipe” or “dynamic vacuum” systems for both insulating capabilities and cost-effective operation. See graph, a comparison of heat input from a normal environment into a liquid nitrogen flow stream.*
