There is a problem of stress analisys that represent an important impact in the evaluation of shells of vessels by WRC 107, this is called the thrust load or thrust force, that for me is an conservative way of analisys of shells, but however always use it. I have had cases when the only application of the thrust force is not withstand for the sell of vessel (why? is bad design of vessel?), but up to now is very difficult explain the "Why Not" use it, although every piping system (arrangement)is different and must has cases where not apply....Do you have any explication?
