COLUMBUS, Ohio -- Dual Seal Flange Adapters from Parker Hannifin
improve the reliability and safety of high-vibration, high-shock
hydraulic four-bolt connections in critical subsea oil and gas
applications. The new adapters are designed as an alternative to
traditional SAE Code 62 Flanges.
Available in standard Code 62 footprint sizes ½” (-8), 1” (-16) and 1 ½” (-24), the adapters incorporate both radial and face seal methods for improved port retention and increased sealing capacity. Together, these technologies reduce the potential for system leakage and air/water ingression caused by side loading of conventional flange face seal connections, thereby reducing the likelihood of a costly field replacement due to failure.
Parker’s innovative Dual Seal Flange Adapters further offer these advantages:
- The primary radial seal improves working pressure rating in certain configurations. Parker has tested its adapters to 7,500 psi (515 bar) with a 4:1 design factor, exceeding current industry requirements for potential dual seal flange adapter connections. Reliability at these system pressures was validated by conducting impulse testing for 1,000,000 cycles. The face seal, meanwhile, resists external environmental pressures.
- Parker added a captive O-ring groove to the traditional SAE J518
flange head. This design further reduces the potential for leaks by
improving seal retention and eliminating O-ring related assembly errors.
The flange head is conveniently interchangeable with commercially
available flange components and hardware because it is patterned after
ISO 6162/SAE J518 flange bolt design.
- The adapters are NACE MR0175 compliant (National Association for Corrosion Engineers; “Materials for use in H2S-containing environments in oil and gas production”). They are constructed from SAE 316/316L stainless steel and are fully Heat Code Traceable. Both the radial seal and face seal O-rings are Nitrile 90 durometer.
