Hydrotest Pressure Exceeded 1

[grosenbalm]

For a 2220# piping system, the hydrotest pressure (3330# - 1.5 x MAWP) was exceeded. The piping system (pipe, flanges, gasket, and bolts) were hydrotested at 6500#. Since this is a test for leaks only and not a test for integrity, i.e. x-ray, are the pipe and flanges still usable or do they need to be replaced? Gaskets and bolts will be replaced. Does the ASME Code reference any of this?
