3" x 20' Cryogenic Transfer Hose — CL 150 | 280 PSIG

What pressure, flow and temperature is it rated for?

This hose is rated for 280 PSIG with Class 150 flanged connections. Flow capacity depends on the specific fluid, acceptable pressure drop, and whether the service is liquid or gas phase—typically a 3" line will handle 100-300 GPM of cryogenic liquid depending on those factors. The listing does not specify a minimum temperature rating; ask the seller for the design temperature range and which cryogenic fluids it is rated for.

What should I inspect before putting it into service?

Since this is listed as new, verify it has been stored properly with end caps in place and no moisture ingress. Inspect the vacuum jacket integrity if applicable, check both flange faces for damage or contamination, and verify gasket seating surfaces are clean. Before cooldown, pressure test with dry nitrogen to rated pressure and confirm the hose flexes freely without kinking at your installation bend radius.
