4 WRC 538 Calculations
INSTRUCTIONS & GUIDELINES FOR USAGE
1 Input values in yellow cells only 1
PLEASE DO NOT TRY TO CHANGE DATA / INPUT IN ANY OTHER CELL
2 Units of input to be selected from pull-down options only.
3 Provisions (designated cells) are made for Optional Input / Project Data :
To be Input only when PROJECT-SPECIFIC DATA ARE AVAILABLE or else displayed default values will be used
4 Results are displayed in 2 sections:
a. in "Result Summary" section - for easy reference
b. in form of detailed step-by-step calculations
5 For Appendix-O calculations, default value of Sfmax
a.  to be
generated using WRC 538: 
i. Select "Yes" from dropdown menu against : WRC 538 Calculation to be considered in PCC-1 Calculation
ii. In the input section by clicking on cell identified by  CLICK HERE it leads to WRC 538 worksheet
iii. Some additional input is required in WRC 538  worksheet, rest is automatically referenced from Appendix-O for the corresponding case
OR
b.  do not generate using WRC 538 (i.e. consider Sfmax = Sbmax) : 
i. Select "No" from dropdown menu against : WRC 538 Calculation to be considered in PCC-1 Calculation
c. Cautionary Note : As some data in WRC 538 worksheet is referenced from Appendix-O worksheet for same case:
    - Do not use WRC 538 spreadsheet in isolation 
    - input data for same case in WRC 538 worksheet as that in Appendix-O

CALCULATIONS
1) Determine Bolt Stress
Step 1: Determine Target Bolt Stress 1
Sbsel , Target bolt Stress 9758.433 MPa 85427.06 lb/in2
Step 2 : Determine if Bolt upper limit controls
1 483.000 MPa 60000.0 lb/in2
Step 3 : Determine if Bolt lower limit controls
1 483.000 MPa 60000.0 lb/in2
Step 4 : Determine if flange limit controls
1 483.000 MPa 60000.0 lb/in2
2) Additional Checks
Step 5 : Check if gasket assembly seating stress is achieved
Check condition 1 2184.724 MPa 49083.3 lb/in2
> 483.000 MPa < 60000.0 lb/in2
Check design O.K.
Step 6 : Check if gasket operating stress is maintained
Check condition 1 7745.442 MPa 57271.0 lb/in2
> 483.000 MPa < 60000.0 lb/in2
Check design O.K.
Step 7 : Check if gasket maximum stress is exceeded
Check condition 1 30586.133 MPa 85895.8 lb/in2
> 483.000 MPa > 60000.0 lb/in2
O.K. O.K.
Step 8 : Check if flange rotation limit is exceeded 483.000 MPa 60000.0 lb/in2
