    Duplex SS - Charpy Testing of Sub-sized Specimens per UG-84

    Table UG84.2 is applicable based on the geometry of your test piece. So it may or may not apply as you haven't provided any specifics. S32205 is a 22 Chrome, have a look at S31803 which is for 22 Chrome.

    Pipeline Welding Techniques

    Sorry to high jack... but I was interested in the G prefix as noted by gtaw. So after a bit of digging I found the ASME/AWS meaning. SFA-5.20 Part C states the following: The "G" indicates that the external shielding, polarity and impact properties are not specified.

    Electrode SFA Numbers ans allowance

    Refer to 5.4.2.6. For (a) no need to re qualify (b) for you to confirm.

    Buttering According to AWS D1.1

    Buttering is generally used for corrections of weld gaps. This would be done to the qualified procedure for that joint. If you have been asked to qualify a buttering procedure by your client, just qualify as per the joint that will be welded and just add additional hardness across the...

    Intepretation of Table from Fig 3.2 AWS D1.1

    I reckon it is the effective throat as defined in 2.24.1.3 (2004 ed). As far as your example, the thinnest part is 12 mm, the pwps would require a minimum leg length of 12 mm, and given your contact size of 8 mm, an economic decision would be required in qualifying the contract weld size of 8...

    Stress Relieving Requirements as per ASME 31.8

    I don't have 2012 but in the 2010 edition 825.3(b) is quite clear and as per your case. ie. thickness of the header governs.

    WPS FOR HOT INDUCTION BEND PIPES

    Same applies to what weldstan says with API 1104.

    ASME VIII UG-22 Clarity for a Engineering Intern

    Nope, you are spot on. Suggest you have a look @ non-mandatory appendix L-2.1.

    Does B31.3 require drain lines to be pressure tested or 100% NDT?

    Kevin, Clause (d) of 2010 edition states: (d) Unless specified in the engineering design, lines open to the atmosphere, such as vents or drains down-stream of the last shutoff valve, need not be leak tested. This was raised in 1983, but was only updated in the code in 2010. Interpretation...

    Welding Procedure Qualification

    As per API 1104 Clause 5.4.2.2, any change in the groupings specified is an essential variable. You have already qualified a c-b, and c-a grouping, so you would need to qualify the remaining c-c, or X65 to X65.

    pneumatic test for pad

    Pressure piping, atmospheric tank, pressure vessel? If you could clarify these, then I'm sure we could give you the exact clauses of American Standards.

    Hardness value for welded joint

    Where is the minimum hardness requirement coming from? Maybe it is referring to the minimum impact energy value?

    UG-16(c) not good enough for AI?

    ConstantEffort, I would have to concur with your understanding. What has worked for me in the past is to sit down with the AI and show them the clause of the code and ask them for their opinion. We never want to be wrong, eh! I'm sure they will agree and will be happy to sign off on the data...

    ASME B31.4-2012 425 Materials Applied to Misc Parts

    Thanks. I might try writing to ASME for the first time and will post the response in some 2 years when I receive it.

    ASME B31.4-2012 425 Materials Applied to Misc Parts

    Hi all, 425.3 and 425.4, limitations are referred to para. 408.4 and 408.5 respectively. I couldn't seem to find 408.4 or 408.5 in my version of 2012 edition. I do have these paragraphs in the 2006 edition. You reckon this has been an oversight in both 2009 and 2012 editions? Or am I...

    Head to shell weld - missmatch on ID or OD

    I generally use a 1:4 taper (14 deg). This is the maximum slope permitted by PD 5500 Figure 3.10-2. A bit more grinding, but smoother transitional has greater benefits.
