    Shell Radiography and joint efficiency

    UT in lieu of RT is very expensive, especially when used with ASME Section VIII, Div. 1. Section VIII requires an auto or semi-auto method of UT (typically phased array or TOFD) and a fracture mechanics based acceptance criteria which means compliance to ASME Section V, Article IV, Appendix...

    Can i re-classify/re-certify a sec I boiler to a sec VIII pressure vessel ?

    There are no Code provisions to permit this. I would recommend you contact the Jurisdiction. They may have a process for obtaining a "state special" permit for this item.

    Interpretation VIII-1-89-264

    I believe there is a typo in "Reply 5" and the second reference to UW-33 should be UW-13(b)(3). If you are outside the UW-33 tolerance you will need to re-fit the joint. The 3:1 taper is only permitted if you are within the UW-33 tolerance. That's they way I interpret UW-33 anyway.

    is it permissible that i can build a same vessel as build 28 years ago

    ASME Section VIII, Div. 1 Appendix 43 requires the current Code to be used. You can't manufacture a vessel to a 28 year old design unless it is reconciled with the current Code. The current Code is based on the date of the contract/PO.

    UG-45 Min Nozzle Thickness

    There is a misconception among some Certificate Holders that small nozzles and fittings are exempt from UG-45 (or UG-44) calculations. Small openings that comply with the requirements of UG-36(c)(3)(a) are only exempt from reinforcement calculations and UW-15 weld strength calculations. All...

    Heater Treater (Emulsion Treater) Firetubes

    FYI... The interpretation you referenced was recently rescinded by the Code Committee and a team made up of manufacturer's and AIAs are working on a Heater-Treater Appendix that will address construction requirements.

    ASME Section I work final hydro in the field under R stamp

    In addition to Metenger's comments, the R Form must indicate the alternative NDE or test method applied to the weld and why a pressure test wasn't performed in accordance with the original Code of construction. See 3.2.2(e) of the NBIC Part 3.

    ASME IX QW 442 A-NUMBER

    This is a recent hot button issue with ASME and National Board. Team Leaders are wanting to see evidence of how the "A" number was determined by the Certificate Holder. For GMAW welding, QW-404.5 requires a chemical analysis of the qualification weld to determine A Number. There are a couple of...

    Nameplate damaged and need to be replaced

    UG-90(c) of ASME Section VIII, Div. 1 requires the AI to verify nameplate data is correct and it is attached to the vessel. NBIC Part 2 requires Form NB-136 be completed for missing or illegible nameplates. The Form must be presented to the Jurisdiction of where the vessel is installed. The AI...

    ASME Sec 1 & IX

    GemmellG, How do you justify using UT to test this coupon? QW-191.2.1 of ASME Section IX only permits use of UT to test coupons on material 1/4" and greater. According to your post the tube is less than 1/4". Unless I am missing something, this coupon should be bend tested or radiographed in...

    Use of Stamps in different states

    Even if the Kentucky "S" Certificate has a "field" scope, you can only perform work at the point of final assembly or installation in Texas. You cannot fabricate "S" Code items in your Texas shop unless that location has their own "S" Certificate or a Temporary Certificate issued by ASME. This...
