Thorburn B96 — Bronze Annular, Single Bronze Braid

The Thorburn B96 — Bronze Annular, Single Bronze Braid is a Bronze annular corrugated metallic hose. Bronze single matched-alloy braid (galvanic compatible). Working pressure to 50 bar at the smallest bore; operating temperature -200°C to +250°C.

Bronze delivers the corrosion / temperature envelope that no stainless grade can match: galvanic-compatible installations on copper / brass / bronze pipework, decorative service, instrument-line connectors, and copper-plumbed water utility.

Construction

• Type: Exotic Alloy Annular — Bronze single matched-alloy braid (galvanic compatible)
• Core material: Bronze
• Braid: Single Braid — Bronze
• End fitting material: Bronze or brass fittings (galvanic compatibility)
• Nominal ID range: DN 6 (1/4") to DN 200 (8")
• Bend radius (static / dynamic): 25 / 125 mm minimum
• Weight: ~0.34 kg/m (size-dependent)

Performance

Working pressure 50 bar (smallest bore, single braid configuration) — derates with increasing diameter and temperature per the OEM datasheet. Burst pressure 200 bar minimum, safety factor 4:1 per ISO 10380. Operating temperature -200°C to +250°C continuous; intermittent excursions evaluated on request. All assemblies hydrotested at 1.5× working pressure with witness-test certificate available.

Applications

• Copper utility piping connectors
• Marine copper-system flexibility
• Decorative bronze installations
• Instrument-line at pressure

Compliance

• ISO 10380:2012 PSL 1 (Corrugated Metal Hoses and Hose Assemblies)
• ASME B31.3 (Bronze)
• EN 10204 3.1 / 3.2 mill test reports on request

How to order

Confirm (a) line working pressure and process medium (specify chemistry, temperature, and any concentration limits — exotic-alloy selection depends critically on the corrosion envelope), (b) operating temperature range, (c) bore size and overall length, (d) end fitting style and matching alloy preference (matched-alloy fittings are recommended for severe service; SS fittings reduce cost where corrosion permits), (e) braid count (drives pressure rating), (f) any required certifications. Indus quotes ex-OEM with mill test reports, alloy-specific certifications, and pre-shipment hydrotest certificates.

Companion products

For severe sour service, ask about the matched Bronze expansion-joint variant. For high-vibration installations, add a Lock-Section or Armor-Flex external hose guard. For fire-rated runs, the Fry-Sil Fire Jacket / Fire Tape can be added without compromising the alloy core. Indus also supplies matched-alloy ANSI flanges, gaskets (RTJ for high-pressure RF), and stud bolts.
