Up Topic Welding Industry / ASME Codes / NDT acceptance criteria
- - By qcweld (*) Date 10-19-2010 05:20
Dear experts,

Need a helps regarding MT & PT acceptance criteria for process piping welds (ASME B31.3).
In which para should be referred for acceptance. In B31.3, its only state MT/PT should be performed according to ASME V.
So far, i am using table 341.3.2 (same as VT) as for evaluating indication. But, column for MT/PT only checked for evaluating crack.
What about surface porosity acceptance or another rounded/linear indication.
Some said their acceptance in BPV code sec.VIII App.6/8.

Please advice.

qcweld,
Surface porosity is evaluated in accordance with BPV Code, Section VIII Div 1, Appendix 4 (See Table 341.3.2 D)
Remember to check Note 5,
Regards,
Shane
