    Consumable tradename change (rebranding)

    Thanks Weldstan, what you stated is correct in most cases. What if the I rephrased my question and rebranding applied to filler metal with a G-suffix (see extract from Section IX QW-404.12 below) or SAW filler metal not classified to an SFA specification (see QW-404.35)? I am trying to cover all...

    Consumable tradename change (rebranding)

    Hello All, I have received an interesting question re filler metal tradenames under ASME Section IX, which I thought had been asked before, but I cannot find it in the ASME interpretations database. I will submit a request for intepretation, but in the meantime, I was wondering if this had...

    P91 joints left as-welded for a long period: how to proceed?

    I am involved with a project where the plant owner 'lost sight' of the site welding contractor for a few months (a wise man used to say: "you get what you inspect, not what you expect!). As a result, hundreds of P91 welds (1.2 to 2in thick) have been left as-welded for months in an uncontrolled...

    Partial welding of pipe test piece for ASME IX procedure qual

    Thanks metengr, I could also thought of welding a longitudinal, rather than a girth weld and treat the pipe essentially as a plate. I will try to talk the client into one of these options.

    Partial welding of pipe test piece for ASME IX procedure qual

    Thanks DD, My concern is that QW-202.1 states that "[test specimens]...shall be removed in a manner similar to that shown in Figures QW-463.1(a) through QW-463.1(f)." QW-463.1(e) shows bend tests removed 90° apart along the pipe circumference, so it seems to imply that the entire pipe shall be...

    Partial welding of pipe test piece for ASME IX procedure qual

    Hello All, I work for a consultancy firm. A client has requested that we prepare a WPS for girth welds in API 5L X65 pipe (25mm thick), to be qualified according to ASME IX. The client also requested that we source the material to be used for the test pieces. These will then be welded and...

    Bolts for cryogenic application

    Metengr, I'm afraid I don't know much about the application all I know is that LNG is involved (storage tanks, I presume). Cheers,

    Bolts for cryogenic application

    Hiya, I'm looking for an alternative to ASTM A193 Grade B8 Class2 material. According to ASTM A193-05 (page 88, bottom of table), the diameter is limited to 1 1/2in., whereas larger diameter bolts are required for the particular application I'm looking at. Is my interpretation of the code...
