ESCE, Inc. has programmed Mandatory Appendix 14 "Integral Flat Heads With A Large, Single, Circular, Centrally Located Opening" in accordance with UG-39(c)(1), large opening that exceeds one-half of the head diameter.        Rules under Mandatory Appendix 14 paragraph 14-1(a), 14-1(b) and 14-1(c) apply.
What could take a day or two of grueling, error prone hand calculations can now be done in two minutes.
All the the drudgery has been taken out of the calculations, including the need for calculating any of the flange factors (i.e. F, V, FL, VL, f, T, U, Y & Z).
All the user needs to do is input the data as discribed in the example problems under paragraph 14-5(a)(1) and 14-5(b)(1).
The program will provide all the stresses necessary to design the opening. These stresses can then be compared to the allowable stresses that are provided under this Appendix.

The program runs only in MathCad 2000 or later.
If you are interested in purchasing the program the total cost is $100.


Description:
Example under paragraph 14-5(a)(1) has a integral flat head with a large centrally located opening with a nozzle attached to the opening (see fig. 14-2) below.

Example under paragraph 14-5(b)(1) has a integral flat head with a large centrally located opening with no nozzle attached to the opening (see fig. 14-3) below.
