2" 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 maximum pressure with CL 150 flanged connections. Flow capacity depends on acceptable pressure drop and vapor density, but a 2" line typically handles 200-400 SCFM for LIN or LOX service; ask the seller for the manufacturer's flow chart. Cryogenic transfer hoses are generally rated for temperatures down to -320°F (LN2/LOX range), but verify the specific rating with the seller as construction varies.

What should I inspect before putting it into service?

Inspect the corrugated inner tube and braid for cracks, kinks, or mechanical damage, paying close attention to areas near the end fittings where flexing concentrates stress. Check both end connections for thread or flange face damage and verify gasket seating surfaces are clean and undamaged. Pressure test with nitrogen before introducing cryogenic fluid, and check for vacuum jacket integrity if it's a vacuum-insulated design by monitoring frost patterns during initial cooldown.
