The Cyclone portable fatigue tester secures a 13.5-inch slickline sample so that the sample has a constant radius of curvature. The slickline sample is then rotated, and the number of revolutions to failure is counted.
Using operator-supplied information (slickline type and bending diameter), as well as the number of revolutions to failure, the included standard Cyclone software (PC-accessible) calculates the slickline segments used life percentage, from which the user may extrapolate the remaining slickline life.
