Rapid Integrity leak Testing (RIT) safely and efficiently tests flange connections prior to operational start up, providing peace of mind and maximising production time. But in a challenging economic climate using bespoke and complex RIT gaskets comes at a high cost.
OUR MISSION
To provide our clients a simple, easy to use and cost effective Reverse Integrity Testing solution that breaks down the barriers of traditional leak testing.
OUR APPROACH
Designed and manufactured in Aberdeen, UK to withstand the harsh environments of the North Sea sector, the patent pending Alba-RIG™ (Rapid Integrity Gasket) is used to validate proper gasket installation on flange connections through hydraulic or nitrogen testing. Rapid verification of joint integrity prior to start up saves time and provides peace of mind. The Alba-RIG™ is designed to be used in Ring Type, Raised Face and Flat Face flanges.
- The Alba-RIG™ - Is fast and easy to install removing complexity and costs
- Giving choice and flexibility in test equipment and process
- Removing the complexity and cost of other leak testing methods and traditional reverse integrity testing
- Making it simpler and more cost effective for operations to adopt Reverse Integrity Testing
THIRD PARTY APPROVAL
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.
Alba-RIG™ - RTJ Version
A certified standard RTJ is drilled to a proprietary configuration optimising metal to metal fusion. A fully annealed high quality tube is prepared and laser welded to the RTJ. In-process inspection is conducted. The tube end is prepared per the application and a standard tube fitting is installed. The unit undergoes visual inspection, 100% leak and pressure testing.
Alba-RIG™ - RF Version
A bespoke dual Kammprofile gasket is manufactured to the highest standards. A fully annealed high quality tube is prepared and laser welded to the gasket. In-process inspection is conducted. The tube end is prepared per the application and a standard tube fitting is installed. The unit undergoes visual inspection, 100% leak and pressure testing.
Gasket thickness: 6 mm
MAWP: 11,200 PSI (770 Bar)
