ASME VIII-1 figure UW-13.2 "tp" value - Center TUBESHEET

ASME VIII-1 figure UW-13.2 "tp" value - Center TUBESHEET

ASME VIII-1 figure UW-13.2 "tp" value - Center TUBESHEET


There is a center tubesheet, welded to shell on both sides.

Per ASME VIII-1, what would be requirement for the "tp" value in this case?
See below sketch.

Would ASME VIII-1 consider just the center part of the tubesheet as "tp" (same OD as shell), or is it safe to consider that "tp" actually starts from the other face of the tubesheet and ends at the weld the other side.


RE: ASME VIII-1 figure UW-13.2 "tp" value - Center TUBESHEET

jakov11000, for tubesheets integral with cylinders I have always taken "tp" to be the (nominal)distance between welds. It is the unwelded land.



The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: ASME VIII-1 figure UW-13.2 "tp" value - Center TUBESHEET

tp = minimum distance from outside surface of flat head
to edge of weld preparation measured as shown in Figure UW-13.2
