Bolt load accuracy is essential to zero leak performance, and control of the bolt preload is essential to achieving bolt load accuracy. ECHO Precision Bolt Load Monitoring ensures accurate bolt load by measuring the bolt stretch. Bolt load that is too low will not maintain suitable gasket stress, potentially leading to poor seals and leakage. Bolt load that is too high can damage the flange, bolt, or gasket, also potentially resulting in leaks and a subsequent safety concern. Attempting to determine bolt load through guesswork can be dangerous and costly and could lead to unscheduled shutdowns. Ultrasonic verification instantly provides a digitized read-out of the true bolt load. Use the ECHO Precision Bolt Load Monitoring to achieve Certainty of Outcome on your critical flanges.
