    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.

    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...

    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.

    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.
