VJ Piping 1" Cryogenic Piping — 200 ft

What pressure, flow and temperature is it rated for?

The listing does not provide pressure, flow, or temperature ratings for this piping. VJ Piping vacuum-jacketed lines are typically rated for cryogenic temperatures down to -452°F (liquid helium service), with pressure ratings and flow capacity dependent on the specific construction and insulation configuration. Request documentation or nameplate data from the seller showing the design pressure, maximum flow rate, and temperature range for this specific run.

What should I inspect before putting it into service?

The listing notes the equipment was not located at the time of listing, so visual verification of condition is essential. Inspect the vacuum jacket for physical damage, dents, or breaches; verify vacuum integrity using a leak detector or by monitoring frost patterns during a cold test; check all end connections, flanges, and fittings for damage or corrosion; and pressure-test the inner line to the rated working pressure. If oxygen service is intended, confirm cleaning certification and perform particle counts before installation.
