Jan 28,2003 allowable stresses of typical asme#0183;There are some question regarding to ASME new allowable stress.1- How does know the reason or philosophy of changing - or better say - increasing of the allowable stress since 1999.2- Is it based on improving of steel making ,vessel fabrication or maintenance systems.3- If we have some modification or repairing ( new nozzle connection ) in old vessel what should it be done regarding to allowable stressA Review Assessment of Current Operating Conditions Dec 14,2009 allowable stresses of typical asme#0183;Time dependent allowable stresses are required in the ASME Boiler and Pressure Vessel Code for design of components in the temperature range where time dependent deformation (i.e.,creep) is expected to become significant.
ASME B31 codes have an allowable of 2/3 of S y for primary stress.For 2/3S y primary stress,from the bree diagram maximum allowable variable secondary bending stress = 1.33*S y; i.e.Sum of Primary and secondary stress = 2S y.Allowable for ratcheting S a = S yc + S yh = 1.5S c + 1.5 S h = 1.25S c + 1.25S h (Taking FOS)ASTM A335 P11 Allowable Stress - Temperature RatingsUsually,the basic allowable stress descends as the working temperature ascends.This relationship is dictated ans specified by ASME B31.1 and ASME B31.3 respectively both of which are ASME code for pressure piping.ASME B31.1 is the standard specification for power piping while ASME B31.3 is the standard specification for process piping.
