NPG CALCULATION OF ASME CODE N-GP-31 Nondestructive COVERAGE FOR SECTION XI, APPENDIX Rev. 0002 Examination VIII ULTRASONIC EXAMINATIONS Page 16 of 24 Procedure (Page 1 of 1)
AUSTENITIC PIPING WELDS SINGLE SIDE ACCESS - SUPPLEMENT 2 Required and obtained examination volume coverage work sheet Below is a typical example of examination coverage plots although are not to be considered inclusive of all situations.
Typical example of a single sided access examination of an austenitic piping weld, examination credit can not be taken beyond the weld centerline when the beam is directed through the weld material.
Although examinations are required to be performed with the ultrasonic beam directed through the weld material, however they can not be considered totally effective or creditable.
Note: Typically a one-sided austenitic weld examination with no circumferential restrictions would be indicated as 75% examination coverage or 50% if circumferential scans were limited to one side.
