Pipe Cut Yield at 99% target pipe cut yield: a worked example

Push target pipe cut yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when reviewing fabrication yield for sprinkler mains, branch lines, risers, standpipe sections, or pre-cut installation kits.

The inputs for this scenario

  • Accepted sprinkler pipe cuts: 238 pipe sections (unchanged)
  • Total sprinkler pipe cuts started: 250 pipe sections (unchanged)
  • Target pipe cut yield: 99 % (raised for this scenario; the documented default is 96)

Working through the calculation

  • Applying the documented formula (Pipe Cut Yield = accepted sprinkler pipe cuts รท total sprinkler pipe cuts started) to the inputs above produces each figure below.
  • At this operating point the engine returns 95.2 % for pipe cut yield, the number this scenario is built around.
  • At this operating point the engine returns 3.8 points for gap to pipe cut yield target.
  • At this operating point the engine returns 238 pipe sections for accepted sprinkler pipe cuts.
  • At this operating point the engine returns 250 pipe sections for total sprinkler pipe cuts started.

How this compares with the baseline

  • Against the tool's baseline example, where target pipe cut yield sits at 96% and the headline result is 95.2 %, this scenario lands almost exactly on the baseline at 95.2 %.
  • It divides accepted sprinkler pipe cuts by total cuts started to give first-pass cut yield, then subtracts that from your target to show the gap in percentage points. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Pipe Cut Yield: 95.2 % (headline result)
  • Gap to pipe cut yield target: 3.8 points
  • Accepted sprinkler pipe cuts: 238 pipe sections
  • Total sprinkler pipe cuts started: 250 pipe sections
