Storage Tank-First Pipe Support Span
Storage Tank-First Pipe Support Span
(OP)
Hi folks, first post.....so go easy 
I have a general question regarding the span between storage tank nozzles and the first piping support for feed and suction lines. I have seen examples where pipe supports are chocked solid within a few feet of the tank and also the other extreme where there isn't a support for maybe 10-15m.
In my view neither is good practice (for different reasons). Does anyone have any views/comments/thoughts/fears etc on this. Also does anyone know of any guidance references in API/ASME/BS/EN etc.
Thanks in anticipation

As said above, there are so many variations that a general rule is not possible, but in many occasions the key to reducing loads and stresses on the nozzle is to have flexibility in your piping design. You sometimes find that putting a valve bolted onto the tank takes up a large percent of the nozzles capacity so sometimes valves need to be moved further away.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
