Subject: Re: [MW:17838] Radiographic Film Interpretation Excess Penetration.. Please explain your secret technique to measure the 3 dimensional defect in RT At first look we should say it is not practical generally to measure the excess penetration from RT film because it is 2-dimensional. But some techniques may be employ to do this measurement by RT. Also some joints may be shown their excess penetration on RT film If you didn't use such techniques and your joint is simple butt joint, so your answer is NO. my question is excess penetration how is measuring the rt film like ruler scale..your knowledge it is possible 1st you mention construction code which applicable if ASME B31.3-2008 then see Table 341.3.2 Acceptance Criteria for Welds and Examination Methods for Evaluating Weld Imperfections as per this
L Height of reinforcement or internal protrusion [Note (8)] in For T w, mm (in.) Height, mm (in.)
any plane through the weld shall be within limits of
the applicable height value in the tabulation at right, ≤ 6 (1⁄4) ≤ 1.5 (1⁄16)
except as provided in Note (9). Weld metal shall merge > 6 (1⁄4), ≤ 13 (1⁄2) ≤ 3 (1⁄8)
smoothly into the component surfaces. > 13 (1⁄2), ≤ 25 (1) ≤ 4 (5⁄32)
> 25 (1) ≤ 5 (3⁄16)
M Height of reinforcement or internal protrusion [Note (8)] Limit is twice the value applicable for L above
as described in L. Note (9) does not apply. so and same like API 1104 have criteria
I have this issue please anyone clarify me, One QA/QC- Inspector 20 years Experience person he rejected one 24" pipe line RT film because of excessive penetration by measuring the dimension with a ruler and required the joint to be repaired.. This is Acceptable or Not Acceptable. if Acceptable where is mentioned the code? Please clarify me, Because my management take this issue very serious --
