    API Riveted Tank -- Repair of Horizontal and Vertical Seams

    Joe -- My apologies, I am not trying to be cryptic. I'm having difficulty envisioning a repair plate that doesn't have at least half of the perimeter fillet-welded to form a lap joint. Wouldn't this then be considered a lap-welded repair patch plate? If so, I'm inclined to apply the criteria...

    API Riveted Tank -- Repair of Horizontal and Vertical Seams

    I'm reviewing the repair plan for an API riveted tank. The plan calls for the replacement of various shell sections including some intersections of horizontal and vertical seams. The shell is 3/8" CS. I've reviewed 653 and have some preliminary issues with how this replacement would be done...

    ASME B31.3 CBT Experiences

    Aconnell -- I also plowed through the VIII-1 CD years ago, but was hoping things had changed... unfortunately not. And some of the errors are, if I can say this without appearing arrogant, very bad. I began writing down all the errors (to relay to ASME), but found I was spending more time...

    ASME B31.3 CBT Experiences

    I would be interested in others' experiences with the referenced ASME CD. I believe the errors and inconsistent rounding of values detracted from the overall experience. Certainly the issues I have with the CD's technical quality resulted in an effort to discriminate good data from bad data...

    weldolet and hot tapping

    I understand this issue may already be resolved for Twinbrooks, but for the benefit of those reading this after the fact, I offer the following: 1. Is the hot tap the last resort? Is it feasible from a process point-of-view? Some processes can not be hot tapped. Some, although possible, may...

    Fox News Sunday Comments Re: Minneapolis Bridge Failure

    Monkeydog, I don't believe I contradicted myself. I stated my "opinion" as such, and not as a statement of fact. What was said this morning, on Fox News Sunday, was stated as fact. If I was unclear, I apologize. I'll be very clear. I am a mechanical engineer experienced in heavy steel...

    Fox News Sunday Comments Re: Minneapolis Bridge Failure

    All, Watching Foxs News Sunday with Mike Wallace this morning, I found myself bothered by comments made by two guests. In essence, they stated the bridge failure was an engineering problem. Without benefit of investigation, they knew what the problem was. Amazing. What bothered me more was...

    Repair of Weld Crack on SA 516 Gr.70 lifting Lug Welding

    Joe -- I have to agree with you. Without knowing the history of this support plate and the associated fillet weld, I would be hesitant to repair and put in service. If the support plate has not been loaded before (i.e. new vessel), then a repair of a faulty weld might make sense. Having seen...

    Saving COMPRESS reports to PDF files

    Tom -- We have COMPRESS build 6252. I attempt to save a report as a PDF, but get an error message that we need to install Acrobat Reader. I have Acrobat 7.0 installed and would rather not install Reader. Any advice? Jeff Lester
