1. When installing , why is it important to use a NON-impacting pneumatic gun? Will an impact gun burst the dti without tightening the bolt enoug to do so? 2. Why should this test be done if the procedure, torqe value etc are set? What value does it add? 3. Is it nessesary to do this check for each lot#? Is there a code you can refference?
Sir, let me knows how much preload developed in bolt assembly with DTI of 5 protrusion of M22 dia. 8.8 grade when we applied 825 NM torque . Also explain with formula.
Thanks for the video.
