I'm trying to find out why there are different allowable stresses for copper nickel piping above and below 4.5" outside diameter. Plate allowable strengths (eg B171) seem constant so I'd think that the allowable stress of the pipe, if made from plate, should be the same if a constant efficiency...
Does anyone know why the flattening test in A106 was moved to a supplementary (S3) test in the 2006a version of the spec as opposed to the previous mandatory test?
104.3.1 (C) indicates that calcs don't have to be performed on reinforced branch connection as long as the fitting and the weld meet 104.3.1 (D). This seems to steer the user into doing the reinforcement calcs. It seems a little contradictory but my question really has to do with what is the...
In an ASME Journal of Pressure Vessel Technology paper (William Koves, Vol 122, August 2000), the author indicates that work was ongoing to develop consistent requirements for fillet welds and the minimum depth of insertion requirements for socket welded joints. I'm specifically interested in...
