KAPA is still fully supported by Kiefner
KAPA is an acronym developed by Kiefner (Kiefner and Associates Pipe Assessment).
The KAPA spreadsheet is maintained by Kiefner and available for download below. The equations used to program KAPA are in the public domain and are still suitable methods for calculating the remaining strength of pipe.
Please continue to use the spreadsheet available for download, it remains a valid tool for conducting B31G, Modified B31G and Effective Area Method calculations. We do not support KAPA spreadsheets that have been obtained by you from a third party.
