Used to obtain the corresponding pressure at ambient temperature. Example when testing Proof or burst pressure to a given value at 300°F, but you will test with corresponding pressure (higher) to ambient temperature.
Example. Proof Supply Pressure @ 300°F = 1161 psig Proof Supply Pressure @ AMBIENT = 1161 X Temperature Scaling Factor = 1161 X 1.15 = 1335 psig
Burst Supply pressure @ 300°F = 1251 psig Burst Supply pressure @ AMBIENT = 1251 X Temperature Scaling Factor = 1251 X 1.24 = 1551 psig
Please note different values for TSF for Proof and Burst pressures. Are these values obtained from the material the part is made off? Is there is a calculation, what it is?
