1) Estimates only. Actual pressures should be calculated considering all stress factors in the system.

 

2) Based on calculations from API 5C3, using a wall tolerance of +/-10%

 

3) Based on ultimate strength burst calculations from API 5C3

 

4) Based on yield strength collapse calculations from API 5C3

 

Adjustment factors for working pressure limits1)

 

Pw = reference working pressure rating for TP 316L at 100°F (38°C). To determine working pressure for grade/temperature combination, multiply Pw by adjustment factor.
