Mustang® Vacuum Jacketed Tubing

Mustang® Vacuum Jacketed Tubing (VJT®) prevents pre-vaporization from Liquefied Natural Gas (LNG) and Natural Gas Liquid (NGL) samples as they travel to the vaporizer ensuring an Analytically Accurate® Sample.

This highly efficient design of the Mustang Vacuum Jacketed tubing utilizes multilayered material within a vacuum-sealed space for efficient insulation of the inner liquid transfer line.

Non-conductive spacers are utilized for the inner line which reduces heat transfer. This flexible stainless steel tubing is custom-designed to meet individual project needs for inner pipe size and overall length. Flow and various application requirements are considered with each engineered unit for continuity of quality.
