I do know the external loads. I also understand the idea about pretension. But in structural applications a torque value is not specified. How do they get away with that? And why can't that same idea be applied to a grade 5 bolt? Trying to avoid specifying a torque. Not sure how accurate it...
My application is an above ground steel storm shelter. Only big enough for two people. Not sure if this is considered structural or not. It doesn't really seem to fit much of what's in the AISC manual. Also, the customer wants to use carriage bolts so the shelter can act as a safe room and not...
My overall problem is that I'm using grade 5 bolts that will be subjected to tension and shear or in some cases just tension. I can't find any guidance on how much external load is allowed. AISC 9th edition lists formulas for allowable tension stress in table j3.3 and allowable stress in table...
I have read through those sections. It's written very general. Not specific. The only section that really tells you anything is the section about Marine Systems. It actually tells you to pressurize the piping from the tank to the nozzles to a specified pressure and that some amount of leakage...
I'm replacing a pilot operated valve that will require cutting the piping on both sides of the valve in order to replace it. We'll end up with a new weld on the upstream and downstream side of the valve. The valve is normally pressurized on the upstream side, but not the downstream side. The...
