If ny of the following essentil vriles re hnged, the welder shll e requlified using n pplile qulified proedure. Question 1: Cn the welder weld ny thikness (Sine he hs overed the highest possile thikness overed in the stndrd) ove inh di pipe or not?

PHMSA regrding wht High Strength Pipe ment in Setion Disussions round this nd the tsk group will len up the proposed wording nd will present it to the suommittee THIS WAS REVIEWED LAST YEAR AND AGREED UPON BUT THE CHANGES NOTED BELOW IN RED WERE WORD SMITHED. THESE CHANGES WILL BE ADDED INTO THE SECTION 6 REVISIONS WITH BILL AMEND S COMMITTEE First prgrph For the end test, if ny speimen shows imperfetions tht exeed those llowed y or , the welder shll e disqulified. Welds in high strength pipe my not end to the full U shpe. Welds might Speimens my not end to the full U shpe in the jig efore reking. If rek ours during the ending these welds speimens shll e onsidered eptle if the speimens tht rk re roken prt nd their exposed surfes meet the requirements of Mteril grouping hrt e inluded in the API Mike Bernsek (mike@spe.om) presented grouping hrt (elow) s sis for review. The hrt is not the refined version ut sis to move forwrd on. There is onern from some memers tht the different SMYS grouping suh s X65 hve multiple listing nd my e onfusing to users nd ould led to ompnies pushing for multiple qulifition with in group. Mike will tke this tsk on with the setion 5 ommittee to llevite these onerns plus refine the list. API 1104 (2013) Bse Mteril Group Mike will work with Roert Lzor nd looking for nother prtiipnt to ssist.. Tle 1 is eing revised. Jon Lee (jonlee@hevron.om) is hiring this inititive.

3 Weld Proedure nd Welder Qulifition Suommittee Minutes of Meeting Jnury 2017 Tsk group tivity to dte: The tsk group met vi onferene ll on numer of different osions. The initil work of the tsk group involved ompiling essentil vriles from other similr welding stndrds inluding AS/NZS , CSA Z662, DNV OS F101 nd ASME B&PV Se. IX. The group then met over series of meetings to disuss eh essentil vrile identified from eh stndrd. Two key points were identified when evluting eh essentil vrile. 1. To e onsidered n essentil vrile for weld proedure development it needs to impt the mehnil properties of the weld. Items identified to impt prodution or welder skill requirements were determined to not e n essentil vrile for weld proedure development. 2. When reviewing n essentil vrile from other stndrds we need to ontinully hek to ensure we re not dding two essentil vriles to ddress the sme onern. The essentil vriles tht urrently exist in setion 5.4 were reviewed using the tehnil knowledge of the group while referening the pprohes of other stndrds. The dditionl essentil vriles from other stndrds were lso onsidered for relevne nd potentil s new essentil vriles for setion 5.4. During our evlutions it ws identified tht the work of the tsk group hd onsiderle synergies with the tsk group evluting the essentil vriles within setion 12. A meeting ws held to disuss joint effort to ddress eh essentil vrile. This ws determined to e neessry to ensure uniformity within the speifition oth from tehnil perspetive s well s in formtting nd style. To split the work the essentil vrile tsk groups (5.4 nd 12) hve reted 4 su tsk groups to tkle the essentil vrile groupings of mterils, onsumles, eletril hrteristis nd method. There is lso work s n oversight ommittee to estlish riteri for lyout nd formt in order to ensure onsisteny. Proposed hnges The following tles identify the possile improvements to some of the essentil vriles urrently in the speifition nd the dditionl essentil vriles tht re identified to hve potentil vlue within API Chnges to urrent essentil vriles: Cluse # Current wording Proposl Consider hnging grouping to e: Bse Mteril A hnge in se mteril onstitutes n essentil vrile. When welding mterils of two seprte mteril groups, the proedure for the higher strength group shll e used. For the purposes of this stndrd, ll mterils shll e grouped s follows. A) SMYS 42 ksi B) SMYS > 42ksi ut 70 ksi C) SMYS > 70 ksi Pge 3 of 11

Both tsk groups hve identified onsidertions tht would signifintly hnge the pperne of API 1104 nd thus need signifint onsidertion efore proeeding. First ws the identifition of need for supplementry or situtionl essentil vriles. Seond ws the need to etter differentite etween speified vriles nd essentil vriles (setion 5.3 vs. setion 5.4). The omintion of these issues hs resulted in onsidertion of proposl to use tulr formt for the essentil vriles in setion 5.4 nd Setion 12. e.
