Free sample questions from ASME.PCC.1

  1. Per ASME PCC-1, what follows from a change to the fastening system?

    • A. Nothing, provided the grade is unchanged
    • B. The nut factor changes ✓
    • C. The target bolt load must be recalculated from the required gasket stress for that joint
    • D. The tightening pattern must be revalidated against the new fastener and lubricant combination
    • E. The joint must be reassessed against the minimum and maximum permissible bolt stress limits

    A lubricant in combination with a stud material and its coatings has a specific nut factor. Change any element of that combination and the torque that was correct becomes wrong. ASME PCC-1, Nonmandatory Appendix K, K-1.2

  2. Per ASME PCC-1, blind flanges and tube bundles hang free of external piping. How may they be aligned?

    • A. Only by hand methods
    • B. With sufficient support or force ✓
    • C. Only after a pipe stress analysis has confirmed that no residual load will be introduced
    • D. Using the same total bolt load caps that apply to flanges connected to a piping system
    • E. By local heating of the flange until the two faces come into uniform contact together

    The load caps exist to stop alignment force being transmitted back into a connected piping system. A component with nothing attached cannot do that, so the restriction does not carry the same purpose. ASME PCC-1, Nonmandatory Appendix E, E-3

  3. Per ASME PCC-1, why does a defect running further across the seating band get less depth allowance?

    • A. Wider defects are harder to detect reliably
    • B. There is progressively less sound surface either side of it to close the path ✓
    • C. A wide defect takes away gasket area and so raises the stress on what remains
    • D. The gasket filler cannot flow far enough sideways to bridge an increasing width
    • E. Flange rotation concentrates load at the outer edge where wide defects occur

    A narrow scratch has plenty of good metal on both sides. Take that away and eventually there is nothing left doing the sealing. ASME PCC-1, Nonmandatory Appendix D, D-3
