, the maximum allowable general primary membrane stress intensity at test pressure API limits this stress to 90% of the yield strength for all materials. 1.3 Temperature effects The effect of temperature on the mechanical properties of the material shall be considered. 2 Elastic Analysis ASME Section II Part D Allowable Stresses Elysium Dec 13, 2016 · The allowable stress tables in ASME II Part D also provide the P-No. / Group No. for the material to be used in ASME IX, the maximum temperature limit the material is permitted to be used at, external pressure chart number reference and notes that relate to the use restrictions of that material.
Allowable stress (S, MPa) in 2013 is on page 78, line 9 Yield strength (Sy, MPa) in 2013 is on page 638, line 17 Ultimate tensile strength (Su, MPa) in 2013 is on page 512, line 17. At 150 degrees S = min (0.9*0.85*161 or 0.85*516/3.5) = 123.17 MPa, which is higher than the listed allowable of 117 MPa. Allowable Bending Stress - an overview ScienceDirect TopicsIn the 17th edition, in 1987, there was a substantial change in the allowable bending stress from a maximum value of 0.66 Fy to 0.75 Fy, and allowance for local buckling was formulated explicitly in the eions. Formulations for three regions are now provided in RP2A which can be classified according to rotational capacity: Allowable Stress - AutodeskFb= 0.60 Fy. (F1-5) If member is in compression, the allowable bending stress is determined as the largervalue from equations (F1-6) or (F1-7) and (F1-8), with the exceptions:Only equation (F1-8) is used for channels. None of these equations apply to tees in compression, thus such tees are not considered.
The allowable stress values used are shown in table A-3 of the ASME Code for Pressure Piping B31.1 1989 Edition for welded pipe to SA-312 with a weld joint efficiency of 0.85. Allowable working pressures shown reflect the minimum wall thickness.
