Senior Flexonics Cryogenic LNG Marine Transfer Hose

The Senior Flexonics Cryogenic LNG Marine Transfer Hose is an engineered specialty assembly. Cryogenic-rated hose assembly for liquefied gas transfer. Vacuum-insulated outer jacket maintains low boil-off and prevents external icing. Inner core Type 316L SS; matched-alloy braid for full liquid-immersion service.

Construction

• Type: Cryogenic Assembly — Marine-grade vacuum-jacketed LNG bunkering hose
• Inner core: Type 316L SS
• Braid: Double Braid — Type 316L SS
• End fitting: ANSI 300# RF flanged with marine-grade vacuum-jacket coupler
• Nominal ID range: DN 100 (4") to DN 250 (10")
• Bend radius (static): 800 mm minimum

Performance

Working pressure 50 bar. Operating temperature -162°C to +60°C continuous. Vacuum-insulated outer jacket — typical boil-off 1-3% per day on standard cryogenic-temperature service.

Applications

• LNG bunkering (ship-to-ship)
• Cruise-ship LNG fueling stations
• LNG carrier offloading
• Marine LNG distribution

Compliance

• ISO 10380:2012 PSL 3
• Pressure Equipment Directive 2014/68/EU Module H
• EN 13480, ASME B31.3, Section VIII Div 1, IGC Code
• EN 13648-1, IGC Code, BV / DNV / Lloyds (selectable)
• EN 10204 3.1 / 3.2 mill test reports on request

How to order

Confirm (a) process medium, (b) operating pressure / temperature envelope, (c) end fitting style and matching alloy, (d) overall length, (e) any specific certifications (CGA, UL, Chlorine Institute, NACE). For cryogenic and steam-jacketed assemblies, also specify the host system interface (vacuum-jacket connection, steam supply pressure, condensate return). Indus quotes ex-OEM with full traceability documentation and pressure-test certificates.

Companion products

Specialty assemblies typically integrate with matched-alloy expansion joints, instrumentation tap-offs, and pressure-relief valves. Indus also supplies complete turnkey skids — cryogenic loading, steam-jacket headers, electric-heat control panels, and chlorine-transfer carts — built around these specialty assemblies.
