P= PD/2(SEW+PY) , pipe thickness calculation a/c to ASME B 31.3 , S = allowable stress value for the pipe material
(and)
P=PD/2000SFET , pipe thickness calculation a/c to ASME B 31.8 , S = Specified minimum yield strength of the gas pipeline
what is the difference between S values , used...
Refer ASME BPVC SEC II Part D, Subpart 1 Stress Tables , TABLE 1A (Max. Allowable Stress Values for ferrous materials) & Table 2A (Design Stress Intensities). I want to know the difference in results we obtained by using each of them and what is their actual difference from theoretical point of...
