Vacuum Jacketed Pipe

Vacuum Jacketed Pipe is the preferred choice for the safe, reliable, and cost-effective transfer of cryogenic liquids including liquefied nitrogen, oxygen, argon, helium, hydrogen and natural gas. The VJP system consists of two 300 series stainless steel pipes: an inner pipe through which the cryogenic liquid flows, and an outer pipe that seals a vacuum space and forms a “vacuum jacket.” Multiple layer insulation (MLI) between the pipes coupled with a low vacuum ensures optimal thermal efficiency. Vacuum Jacketed Pipe efficiently transfers liquids at pressures up to 150 psi or greater. These systems minimize heat leaks to maximize efficiency and savings over time.

OVERVIEW

When an off-the-shelf, one-size-fits-all approach won’t do, you can trust Acme’s Vacuum Jacketed Pipe systems to meet your unique performance requirements. The Acme Cryogenics team designs manufacture and test our vacuum insulated piping and components using the highest available standards. All Inner Process and Outer Jacket Welds are Helium mass spectrometers tested at 1 x 10-9 cc/second, sealed at 9 microns or less.

Components

In addition to VJP, Acme provides a complete component offering to complete our system design, manufacture, and installation capability.
Mechanical Keep-Cold Device
A float-activated device used to maintain liquid in the VJ Pipe line and vent the excess gas created by normal heat leak.
Phase Separators
Typically used in applications where a single bulk tank is being used to provide both high pressure (90-150 psig) nitrogen gas and low pressure (5-30 psig) liquid nitrogen.
Scale-Based Tank Switcher
Used in applications that require multiple liquid cylinders to be used in succession without interruption by automatically switching to a new cylinder as each cylinder is emptied.
Vacuum Jacketed (VJ) Valves
Designed to have low heat leak and will not frost up during operation for in-line isolation or where superior thermal performance is required.
Internal Gas Traps
Used at the vertical drops/use points and designed to keep liquid nitrogen from “sitting” on uninsulated valves or components.
Vacuum Jacketed SuperFlex Hose
Remains warm and flexible during the transfer of cryogenic liquids. The vacuum insulation minimizes product loss and eliminates ice buildup.
CryoFast
Laboratory grade, high-efficiency VJP designed to quickly deliver LN2 for low flow applications with a limited LN2 source. Combine with VJ SuperFlex Hoses to provide frost-free LN2 delivery from Dewar to your storage freezers.
Quick-Fab Modular VJP
When time is critical, Acme offers pre-engineered VJP with mechanical foam joints in a one to two week lead time. Modular sections are offered in various length straights, with VJ elbow and tee sections that can be assembled for a fast, low cost, and low heat leak VJP solution.
