Bolt Tensioning & Torqueing

Controlled Bolting – Flange Integrity Management

Tightening any joint or flange with the wrong techniques or values can impact the integrity of the plant or asset as well as increase potential risk of damage or injury to plant or personnel

Pretect operates a comprehensive flange management system and applies controlled bolting value/techniques to all flanges tightened or untightened which guarantees that joints are tightened to the correct value and that joints are compressed to optimum force applied.

Pretect flange management system allows operators to comprehensively monitor the progress of flange/joint progress throughout its application when bolting services are undertaken.

The tagging system process and computer logging records maintained during the implementation provide the client with a comprehensive flange management record and historical log of the integrity of the joints or flanges for future reference.

When the Pretect flange management system is applied during outage scenarios this allows the client to have a day by day progress report and have confidence that on start-up that the risk of flange leak incidents have been minimized
