Temperature derating factor for steel pipe

WebAs temperature increases, the pressure rating of the flange decreases. For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F. In other words, when the pressure goes down, the temperature goes up and vice versa. WebT = Temperature derating factor. The design factor to be used in the calculation of the design pressure in the above formula is dependent on the Class location of where the …
