    01. What is the formula used for hydro-test pressure calculations per CODAP Div. 1 used for Shell and Tube Heat Exchangers in AutoPIPE Vessel?

    Problem:

    Formula for calculation of hydro-test pressure as per CODAP Div.1 is:

    MAX(1.45*PS, 1.25*PSr*(fE/ft))

    Is this correct?

    Solution:

    To consider the MAWP for calculation of hydro-test pressure with CODAP, select “use PED” in Design Parameter Tab.

    Note:  the MAWP cannot be determined when the design failed (insufficient thickness), in in this case the MAWP must be input.
