Product description
The Thorburn Thor-Loop Series VL "V-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 — V-shaped pipe loop motion absorber (replaces metal expansion joints)
- Inner core: Type 321 SS
- Braid: Double Braid — Type 304 SS
- End fitting: ANSI 150# / 300# / 600# RF flanged ends (selectable)
- Nominal ID range: DN 50 (2") to DN 250 (10")
- Bend radius (static): 1000 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
- Steam-line pipe motion (replaces bellows expansion joints)
- Hot-process plant piping
- Power-generation steam mains
- Long-run process piping with thermal expansion
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.
