Thorburn S50HD Type 321 ultra-HP compressed helical hose with double Type 316 SS matched braid. Closed-pitch helical for HP service requiring vibration absorption.
The Thorburn S50HD — Ultra HP Compressed Helical, Type 321 SS is a high-pressure metallic product. Ultra HP compressed helical (Type 321 with 321 braid) for service that exceeds the rating envelope of standard SS Annular hoses. Working pressure to 350 bar.
Working pressure 350 bar (smallest bore, double braid configuration). Burst pressure 1400 bar. Safety factor 4:1 per ISO 10380. Operating temperature -200°C to +650°C continuous. All assemblies hydrotested at 1.5× working pressure with witness-test certificate available.
Confirm (a) line working pressure (or for fire-protection: the host hose specification), (b) operating temperature range, (c) bore size and overall length, (d) end fitting style, (e) braid count where applicable, (f) any required certifications. Indus quotes ex-OEM with mill test reports and pressure-test certificates.
Pair with matched-pressure flanged or threaded fittings, plus thermal insulation jackets for elevated-temperature service. Indus also supplies matched ANSI flanges, gaskets, and stud bolts.
