Is WRC-107 acceptable to ASME VIII Div.1 for calculation of external loads on nozzles.
I don´t have any program for WRC-297, what is the difference between these two standards.
Calculation of tubesheets.
I´m designing floating head heatexchangers with double tubesheets, TEMA Fig. RCB-7.126.
The inner tubesheets are as follows.
Fixed side: Tubesheet gasketed with shell, extended as flange.
Floating side: Outside packed tubesheet.
The outer tubesheets are as follows...
To use M=1 in calculating tr of head, all reinforcement has to be entirely within the spherical portion of the head.
Does that mean that as an example: The centre of a I/D 6in nozzle is located 5in from the edge of the spherial portion of the head, that if the area A1 and A5 is limited to a...
Thanks gr2vessels for your answers.
To clarifie my question re. torispherical heads with mts exeeding 70000 psi.
The question is: The head is calculated with S eqal to 20000 psi @room temp redused in......
A nozzle and its reinforcement areas are located within the sperical portion of head.

Calculation of flange acc. to 2-4(9), pipe wall considered
to act as a unit with the flange.
Is it OK to calculate the flange/pipe unit as an optional integral flange even though there isn´t a full penetration weld between the pipe and flange, using loadings and dimensions acc. to fig. 2-4(7)...
