We say its not the position of the Code to provide a cook book on how to tackle trunnions etc.
Indeed, I have seen xx number of different ways in which the same method (Kellogg) is implemented.

So how is ones work in such area's checked?.

This is relevent to myself, as i have a body of work being check oversees as we speak. in this work, the trunnions are critical, and i expect a fire fight as to the right way calculate them.

I am on my one in this company, and am not the most experianced stress engineer on this forum.
My company will not pay for FE pipe or any books etc, and the papers used by engineers (kellogs etc) are part of a fast dissapearing black art.


it seems that alot of other people are intrested in these kellogs papers, i wonder why?


My point is this. Surely the critical design of potentially leathal pipework should not be based on whispers, rumours and the 99th copy of an obscure 60 year old 'pamplet'
