I love this job

Great video!

Hello sir, can you teach me , how to convert lbf-ft to Psi

[@PaulDanciu]

what is difference between pressure A (it is the final target?)and pressure B how much % need to be applied

[@Lokeh81]

When working with tensioners like this, our goal is to end up with a preassure close to, or slightly higer than B. Ax3+Bx3 = close to B. Your equialized preassure between A and B. So, if you move one of the tensioners back to a random A-bolt and test it, if you have done this correctly, you'll see it releases close to B. if not, if the preassure is alot higher than B or alot lower than B, you need to start all over again.

When tensioning in 50% configuration, Pressure A is Pressure B x CLF. Cross Load Factor (CLF) can range from 1.15 to 1.25 Pressure B is calculated considering the residual load x LTF (Load Transfer Factor). the LTF depends on the grip length or the effective length of the joint and the bolt nominal diameter LTF=1.01+(diameter/grip length).

👌

This is misinformation. Its VERY important that your bolts gets to rest between your cycles. If you preassure to A, turn the nuts and release preassure, the bolt will need around 30 mins to return to its original form. If you dont let your bolts rest between cycles they will not be tensioned any more and the nuts will not turn on cycle2, or 3.
