KAPA
Predicted failure pressure of corrosion and other metal loss, from length and depth or a full river-bottom profile.
ASME B31G, Modified B31G, Effective Area Method
PipeProps
Likely API 5L grade of a pipe from its dimensions, strength, chemistry and install year, with the probability of each grade.
Kiefner PipeProps model, Monte Carlo measurement uncertainty
CRAFT
Kiefner Crack-Like Flaw Assessment Toolkit: failure pressure of crack-like flaws.
Modified Ln-Sec
NWT Estimator
Kiefner Nominal Wall Thickness Analysis: the most probable nominal wall thickness of vintage pipe joints from UT readings, by OD and install year.
API 5L tolerances 1927-2004, API 5LX 1948-1982, 10-year window
Pipelife
Remaining fatigue life of axial crack-like flaws under a recorded pressure history: clean and rainflow-count station pressure data, then grow flaws by Paris-law crack growth.
Rainflow (ASTM E1049), Modified Ln-Sec, Legacy 2017 mode
