B31 code case 179

Dear All,

Just wondering, do you know where can I get a copy of the B31 code case 179 'Use of Alternative Ultrasonic Examination in Lieu of Radiography for B31.1 Applications in Materials ½ inch and Less in Wall Thickness'. I've checked with IHS, and they do not have it.

Re: B31 code case 179
B31 Case 179 (for B31.1) — "Use of Ultrasonic Examination in Lieu of Radiography for B31.1 Applications in Materials 1⁄2 in. and Less in Wall Thickness" is published in ASME B31.1b-2006, Addenda to ASME B31.1-2004, Power Piping, page C-22. (B31.1 itself only allows UT on wall thicknesses greater than ½ inch.)

B31 Case 181 (for B31.3) — "Use of Alternative Ultrasonic Examination Acceptance Criteria in ASME B31.3" describes conditions for fracture mechanics evaluation of flaws. Almost identical to Code Case 2235, except that there is no lower limit on wall thickness.

Re: B31 code case 179
The link provided takes you to what is for B31.3 (Case 181) and a couple other Cases however the 179 is not in the document. Are you saying Case 181 applies in lieu of 179?
