Quik-Fab modular VJ pipe is a vacuum insulated pipe for the transfer of cryogenic liquids. It is configured from pre-engineered straight sections, 90 degree elbows and tee sections, and each joint is a foam joint protected and sealed by a stainless steel sleeve. It comes in four sizes from 1/2" x 2" to 3" x 5".
