The operators of the plant are now planning to extend the use of the technology not only across other pressure containment applications, but also in a working environment where sustained vibration has caused bolt loosening.
The 2000 megawatt coal fired power station first began using RotaBolt measurement technology in 2009, when sixteen M45 x 250mm RotaBolt studs were fitted on a steam flange operating at 540°C. The flange had a track record of reliability issues but once fitted with the technology it became leak-free and has operated reliably ever since.
RotaBolts were then fitted on another flange between a steam boiler and a turbine carrying super heated steam and also on a further application on a steam valve. These joints have remained reliable since conversion and now the operators are planning to use the measurement technology on a second steam boiler as well.
Following the success of achieving joint integrity in these pressure containment applications, the operators of the plant are now planning to use RotaBolts to prevent vibration loosening on foundation bolting on a crusher machine that is subject to prolonged vibration.
RotaBolts are being increasingly used around the world to assure bolted joint integrity in any application where pressure containment, vibration, fatigue or structural slippage are an operational issue.
