RE: [MW:8582] phased array vs. RT

Hi:

Standards are not silent about replacing RT with AUT. ASME Section V has
recently published five Mandatory Appendices, two on phased arrays and
three on AUT, to replace Code Case 2235. See ASME Boiler and Pressure
Vessel Code, 2010, Section V Article 4, Mandatory Appendices IV-VIII.
They are "all there".

Yours,

Michael Moles

Standards are silent about the replacement of RT by phased array UT.

My experience says that you will have to proove and convince your
customer / TPI by demenstration that the defect detected by RT is
equally detectable by Phased array UT.

Ultimately it would be decision of your customer whether to allow or
not...
