My question is will the lock ring splay out during pressure testing? Please let me know if you need any additional info.

In my opinion all CAD softwares are similar interms of logic they use to build a model, its only the GUI that differs. Just start learning a standard CAD software, Once you've done it I am sure you will be able learn other softwares in no time.

Dear Members, The existing design for the pressure vessel is an end cap bolted to the body which is not designed to any pressure vessel code. Currently I'm trying to qualify this pressure vessel to PD5500 code. Due to the derated allowables in the code i couldn't go with the bolted...

could someone please help me in this regard.

The minimum recommended length of engagement is 0.75 to 1 times the bolt major diameter for threading into steel and other materials of comparable hardness; and 1 to 1.5 times the bolt major diameter for threading into brass, cast iron, and aluminum. These lengths of engagement specified are...

To make things simple. the length of engagement of bolt = diameter of the bolt. But i don't know how to prove that it won't fail. I couldn't find a concrete material for this. I am a kid in this field. So i need your advice.

Thanks for your reply. I think the formula what is stated (FOR Shear area) is of no use. What I'm looking for is a derivation or a formula which can say that the bolt won't fail due to shear stress, if Length of engagement between = the dia of the bolt. But unfortunately i couldn't find it...

The shear stress in thread. Thanks for your response :)

Hi How can i derive an equation to prove that a bolt won't fail due to shear stress if the length of thread engagement of the bolt with nut is equal to the diameter of the bolt. I got a formula, but i don't know whether it is useful in this case. A_s,e = pi*n*L_e*K_nmax*[1/2n +...
