Thorburn M96 — Monel 400 Annular, Single Monel Braid

The Thorburn M96 — Monel 400 Annular, Single Monel Braid is a Monel 400 annular corrugated metallic hose. Monel 400 single matched-alloy braid (chlorine-rated). Working pressure to 100 bar at the smallest bore; operating temperature -200°C to +540°C.

Monel 400 delivers the corrosion / temperature envelope that no stainless grade can match: dry-chlorine transfer per Chlorine Institute Pamphlet 6, sea-water and brackish-water service, alkaline streams, and sulphuric acid up to mid-concentration.

Construction

• Type: Exotic Alloy Annular — Monel 400 single matched-alloy braid (chlorine-rated)
• Core material: Monel 400
• Braid: Single Braid — Monel
• End fitting material: Monel 400 fittings standard
• Nominal ID range: DN 6 (1/4") to DN 250 (10")
• Bend radius (static / dynamic): 30 / 150 mm minimum
• Weight: ~0.32 kg/m (size-dependent)

Performance

Working pressure 100 bar (smallest bore, single braid configuration) — derates with increasing diameter and temperature per the OEM datasheet. Burst pressure 400 bar minimum, safety factor 4:1 per ISO 10380. Operating temperature -200°C to +540°C continuous; intermittent excursions evaluated on request. All assemblies hydrotested at 1.5× working pressure with witness-test certificate available.

Applications

• Liquid chlorine transfer (Spec 135-3)
• Sea-water service at pressure
• Caustic alkaline transfer
• HF process plant

Compliance

• ISO 10380:2012 PSL 1 (Corrugated Metal Hoses and Hose Assemblies)
• Pressure Equipment Directive 2014/68/EU Module D
• ASME B31.3 (Monel)
• Chlorine Institute Pamphlet 6 + Specification 135-3; CSA B51
• 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 Monel 400 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.
