I would like to know what is the approximate percentage of water settlement in a heavy fuel oil (HFO)and high speed diesel (HSD) storage tank. we need to design and provide a provision for removing this quantity of water from this tank? Appreciate all the help

big inch... the allowable stress is based on the yield right? our use of allowable stress is to ensure that the material doesnt yield.I understand the fact that utlimate tensile is greater for SS but if allowable for SS is kept high, the room between allowable and yield is less for SS which...

Can anybody give a detailed answer as to why the allowable stress of carbon steel (A 106) is 50% of its yield strength and the allowable stress of stainless steel is 70% of its yield strength? B 31.3 also specifies for flanges that when we are dealing with stainless steel the allowable can be...

rmw thanks for all the help man.. it has helped clarify many concepts. Uzair

rmw, thanks for all the help man. Really appreciate it! i will ask a few qs i have had on the points discussed. 3) By this you mean that the other anchor would slide to take the expansion of the pipe into account and reduce the load on the other anchor? 6) what i meant was that a 2 but tied...

rmw, Firstly thankyou for a such a detailed respnse and explanation on the matter. I agree with you both that this topic is fairly misunderstood and thats why many engineers always prefer expansion loops. 1) They way i understand from your discussion, the tied bellow (2 nuts only) wouldnt...

Can someone please reply? what is the essential difference between these two forms of tied expansion bellows?

and also.. as one can visualize, the higher temperature difference (for expansion) the better effective the joint would be axially to work against the pressure thrust and wrk better. I was told by a senior engineer that there was a graph of linear relationship between temperature and pressure...

I understand that the 4 nut one,in which the bellow isnt allowed to either compress or expand behaves in pretty like a rigid structure. Such an expansion bellow (tied completely ends) is installed in the direction perpendicular to the direction of expansion and the bellow works 'laterally'...

I am given to understand that tied expansion bellows do not take any axial load and only lateral loads. But what about the bellows which have tie rods with nut on the outer side only. On the flange side and not on the bellow, this would mean that the tie rod is engaged only when the bellow...
