B31.3 Reduction in Lowest Exemption Temperature Without Impact Testing - CAESAR II - Help

For B31.3 analysis, CAESAR II uses Fig 323.2.2B or Table 323.2.2B for temperature reductions.

Adapted from: B31.3 - 2018, Process Piping, Fig. 323.2.2B, Reduction in Lowest Exemption Temperature for Steels Without Impact Testing.

Unit conversion

For Tmin, base MDMT, and final MDMT, Fahrenheit converts to Celsius by:

°C = (5/9)(°F – 32)*

Reduction converts according to the Celsius/Fahrenheit ratio used on the horizontal axis of Figure 323.2.2B:

Reduction °C = (5/9)(Reduction °F)
