Alba's patent pending Rapid Integrity Gasket (Alba-RIG) has received 3rd party product design approval (PDA) certification from the London office of the American Bureau of Shipping (ABS).
The certification covers onshore, offshore and subsea flange connections up to ASME 2500 class and API 10K with a maximum allowable pressure of 11,200 PSI / 770 bar.
The Alba-RIG comes in two forms, a dual kammprofile version for raised face and flat face connections and a ring type joint version.
All Alba-RIG ring type joints are manufactured to the standards set by the American Petroleum Institute, and the American Society of Mechanical Engineers, using fully traceable materials, from mill certification to final supply and with strict quality assurance procedures that exceed API 6A PSL 4. Each Ring Type Joint is low stress stamped for identification and traceability. Soft iron and low carbon steel rings are protected with electroplated zinc in accordance with specifications. Alba-RIG ring type joints are available in Octagonal, Oval, RX and BX cross sections in a comprehensive list of materials and rated up to 15,000 PSI.
BX cross sections are manufactured with an extra 5mm height for the test port to clear the flanges. The extra height has minimal effect on tension, load or stress and can be calculated by all bolting specialists.
The product has been widely used by multiple global oil and gas clients and is now available from a network of global distributors and agents. Please get in touch for further details.
