LAC 43:XIII.915. Temperature Derating Factor (T) for Steel Pipe [49 CFR 192.115]
Cite as La. Admin. Code tit. 43, pt. XIII, § 915
A. The temperature derating factor to be used in the design formula in §905 is determined as follows.
Gas Temperature in Degrees Fahrenheit (Celsius) | Temperature Derating Factor (T)
250F (121C) or less | 1.000
300F (149C) | 0.967
350F (177C) | 0.933
400 F (204C) | 0.900
450F (232C) | 0.867
B. For intermediate gas temperatures, the derating factor is determined by interpolation. [49 CFR 192.115]
