Answer:

This is the value which allows the user to obtain in the calculation as an external pressure the value equal to the overpressure minus the internal pressure of the vessel.

For example:

Overpressure = 50 MPa; Internal pressure of the vessel = 2.5 MPa

then External pressure used for blast = 47.5 MPa (50 – 2.5)

05. What value for overpressure need to be entered for blast load condition in AutoPIPE Vessel?
