KAPA is fully supported by Kiefner.
KAPA is an acronym developed by Kiefner (Kiefner and Associates Pipe Assessment).
Kiefner maintains the KAPA spreadsheet, which is available for download below. The equations used to program KAPA are in the public domain, but they are still suitable methods for calculating a pipe’s remaining strength.
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 you have obtained from a third party.
