Thorburn Thor-Loop Series UL "U-Loop" Flexible Pipe Loop

The Thorburn Thor-Loop Series UL "U-Loop" Flexible Pipe Loop is an engineered specialty assembly. Thor-Loop flexible pipe loop. Replaces traditional metal expansion joints with a longer-life metallic-hose-based motion absorber. Accommodates axial, lateral, and angular pipe motion without bellows fatigue.

Construction

• Type: Pipe Loop / Expansion Joint — U-shaped pipe loop motion absorber (compact alternative to V-Loop)
• Inner core: Type 321 SS
• Braid: Double Braid — Type 304 SS
• End fitting: ANSI 150# / 300# / 600# RF flanged ends
• Nominal ID range: DN 50 (2") to DN 200 (8")
• Bend radius (static): 800 mm minimum

Performance

Working pressure 100 bar. Operating temperature -200°C to +650°C continuous. All assemblies hydrotested and pressure-certified per applicable specifications.

Applications

• Compact pipe-rack expansion compensation
• Indoor process plant piping
• Refinery / petrochemical pipe-rack
• Power-generation auxiliary lines

Compliance

• ISO 10380:2012 PSL 3
• Pressure Equipment Directive 2014/68/EU Module H
• ASME B31.1, B31.3, Section VIII Div 1
• NACE MR0175 / ISO 15156 (sour-service compliant)
• CSA B51
• 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.
