Vacuum Jacketed Pipe is essentially two pipes in one - an inner carrier pipe in which the cryogenic liquid is transferred, and an outer pipe that supports and seals the vacuum insulation, forming the “Vacuum Jacket” around the inner pipe. The inner line is suspended inside the outer jacket by a series of non-conductive supports. Depending on system design pressure, internal or external expansion joints are used to compensate for thermal contraction of the inner line.

The inner carrier pipe and the outer jacket are constructed from stainless steel pipe or tubing.  The inner line is wrapped with a multi-layered super insulation which blocks radiative heat transfer.  The entire annular space between the inner line and the outer jacket is evacuated to prevent convective heat transfer. The vacuum space is then factory sealed, forming a “static vacuum”.

The result is the most efficient transfer system available for cryogenic liquids.
