Dear Members,

12” Sch 40 Carbon steel pipe,
Design Pressure – 47.5 barg
Design Temp – 84 deg C

Approximate length 3000 meter

Please clarify the following query,

Is the pressure stiffening effect and Bourdon effect shall be considered simultaneously?

In case of ASME B31.4, the pressure stiffening effect is applicable, and can I also activate the bourdon effect at the same time.

As the bourdon and pressure stiffening effects are related to the displacement due to pressure.

Please clarify...
