CANDUNUCLEAR - Thorburn Flex

1 Thorburn Flex IncFlexible Piping SpeciaServing the candu nuclear Community Cryogenic Quick CouplingsThorburn Flex IncFlexible Piping Series - Non-Valved Full Flow Cryogenic CouplingsBall Bearing Locking MechanismExtended Sleeve HolderUHMW Polyethylene SealCompression SpringCoupler / Socket HalfNipple / Plug HalfRetaining RingThorburn s NT52 Series cryogenicquick coupling system is designed, engineered & manufactured to pro-vide safe, reliable, leak tight quickconnect & disconnect for cryogenicfluids. Thorburn s NT52 is an ideal quick coupling to replace threaded uniontype connectors where speed and convenience is a requirement. TheNT52 standard seals are made ofUHMW polyethylene making it ideally suited for radioactive nuclear of UHMW PE (Ultra High Molecular Weight Polyethylene)seal Low temperature up to -452F without material degradation Self-lubricated material with low coefficient of friction, that reduces force required to connect / disconnect coupling halves High impact strength and abrasion resistance that outwears carbon steel 10 to 1 Good chemical resistance to organic solvents, de-greasing agents and electrolytic attack.

2 Very low moisture absorption that prevents ice formation when used for low temperature fluidsTemperature ranges down to -269 C (452 F)Features & BenefitsBall Bearing Locking Mechanism Multiple ball bearings for better load distribution Live swivel to eliminate torsion load Facilitates alignment during connectionExtended Sleeve Holder Larger gripping spaceCompression Spring Automatically returns the sleeve to its original positionStandard UHMW Polyethylene Seal Ideal for liquid nitrogen service in radioactive environmentsUltrasonic Cleaning Removes contaminates & minimizes frost build upQuality & Design ASME Section III/CSA Classes 1, 2, 3 & 6 Full traceability of all pressure retaining components CRN for all Canadian Provinces 2014 Thorburn Flex Drop (psi) Flow Rate (GPM)
