allowed deflection between two supports in steam piping - 03/24/17 03:08 AM
If I have piping coming from CPP area governed by ASME B31.1 to Refinery OSBL rack and then ISBL - what should be the allowed deflection between two supports in steam piping for piping span fixation ?
B31.1 asks for 2.5 mm between supports, where outside B31.1 it can be 10 mm as per our standard fog general purpose.
Unless we keep a good slope like 1/200, in refinery application -it can to zero to 1/500 for steam piping sometimes in rack - is the piping not prone to condensate accumulation and prone to damage due to condensate driven water hammer ?
