Woburn, MA – February 2004 – Vacuum Barrier Corporation the original manufacturer of SEMIFLEX® dynamic vacuum insulated flexible piping proudly adds a sealed version to this time proven product line.

Sealed SEMIFLEX® is constructed from copper to provide the lowest cool down and steady state loss – similar to existing dynamic SEMIFLEX® piping. Frost, moisture and ice ball problems commonly associated with foam insulated or soft vacuum lines are eliminated with Sealed SEMIFLEX®. The smooth contours in the pipes design allow for a higher liquid nitrogen flow capacity while the ultra clean copper pipe provides the highest purity liquid nitrogen.

Sealed SEMIFLEX® is a cost effective solution for a variety of cryogenic applications. Each pipe is helium leak tested and cold shocked to ensure its vacuum integrity. To achieve the longest service life in the industry every pipe is heat soaked during evacuation and is equipped with chemical getters.

Since 1958 Vacuum Barrier Corporation has designed, fabricated and engineered cryogenic equipment in their Woburn, Massachusetts facility and has remained a leading supplier to the Food and Beverage, Semiconductor, Automotive and Lighting industries worldwide.
