A continuous weld is what the employer would like to have all the time. An intermittent weld is when the welder has regular breaks for a smoke or a chat with the guy working beside him. [pipe]

jm2804, No, it will not require re-qualification. API 1104 Clause 5.4.2.2 notes "b" Specified minimum yield strength - not actual yield strength. The specified minimum yield strength for X60 as per Table 3 of API 5L is 60,000 psi minimum with 82,000 maximum. As long as you have definitely been...

metengr, Thanks for the response but what about my questions regarding the ER70S-6 ? Cheers, Kiwi

Stanweld, Thank you for the response but it hasn't helped me understand. If I qualify a PQR with an electrode (ER70S-6) that has a batch certificate showing Mn of 1.40 then I can class it as an A-1 or A-2 (how do you decide if it is actually A-1 or A-2 ?) What if I have a PQR/WPS that states A-1...

Metengr, Can I possibly ask for assistance with understanding the chemical composition requirements please. SFA 5.18 ER70S-6 SFA 5.28 ER80S-D2 Both wires comply with QW 442 A-1, A-2 & A-11 for C, Cr, Mo & Ni A-1 & A-2 list a maximum Mn of 1.60 SFA 5.18 ER70S-6 lists an allowable range of...

zdas04, My sincere apologies for hijacking your post but wanted to respond to Staniers comments. Stanier, Your comment that the Australian pressure piping code - AS 4041 is not based on ASME is a bit strange as the Foreword of AS 4041 states ASME B31.1 & B31.3 are a major source of material...

zibaeng, You ask an impossible question. The code or standard you are working to tells you the requirements for impact testing. Materials, thicknesses, MDMT etc will determine whether impact testing is required by that specific code or standard or not, Regards, Kiwi

Silje, It is your responsibility to design (and manufacture if in your scope)as per your contract and contract specifications. If there are additional requirements (eg. called up in AS 1210)or other Australian regulations it is your customers responsibility to request compliance. Regards, Kiwi

Gen B, Does not have to be on code construction work - can be on a tin can or a tractor or an instrument. Obviously from an employers (or clients) perspective coded work would be preferable but not required by the ASME IX code, Cheers, Kiwi

XL83NL, Does this help ? http://cstools.asme.org/CodeCases.cfm Just enter the Code Case number and it tells you when it was approved and whether it has been annulled yet Cheers, Kiwi

Jorge, You are in a difficult position and the only person who can adjudicate is the Owner or the Owners Engineer. The project inspector is only giving you his opinion. 9.1.1 The basis for repairs and alterations shall be an API Std 650 equivalence 9.2.3.4 To reduce the potential for...

Luiz, As RConnor has stated if it complies with all the requirements of both it can be dual certified - no problem, Cheers, Kiwi

Luiz, TP 304 0.08% max TP 304L 0.035 max Hope that helps, Regards, Kiwi

Thanks Weldtek, As it is Non Mandatory P-Numbers does that mean they are classed as Assigned or Un-Assigned materials ? (Or is that Listed or Unlisted materials ?) Cheers, Kiwi

Weldtek, Cannot locate S235 JR in ASME IX 2010 QW422 - where did you find it ? Cheers, Kiwi

moltenmetal, After my first response I looked again and Bonney Forge make sockolets up to 6" outlet size (Cl 3000) and they also make 4" and 6" size to size sockolets so somebody is welding 4" sockolets on to 4" pipe somewhere. Still think the Tee is the best idea for a variety of reasons -...

What code / standard are you welding to ? You can't just state "Will ABS require it". More info needed, Regards, Kiwi

billb12, Something does not sound right. 4" Sch 160 run pipe with a 4" socket weld ? Why would you not install a 4" tee ? Cheers, Kiwi

Here is the interpretation that metengr mentioned (I hope it is the correct one. LOL) Interpretation: I)<-95-38 Subject: Section IX, QW-322, Expiration and Renewal of Qualification Date Issued: January 6, 1997 File: Question: Is it a requirement of QW-322 for a manufacturer to maintain records...

No requalification required. See QW 353 / QW 402.4 Deletion of backing is an essential variable, not the addition of backing. Regards, Kiwi
