Tube, Pipe & Profile Forming calculator

Line OEE Calculator

Find line OEE from planned time, stops, validated ideal tube cycle and observed counts. Enter first-pass good output separately from total output and compare with your own OEE target.

What this calculator does

  • Measure how much planned tube production time became first-pass good output at the validated ideal cycle.

Formula used

  • Running minutes = planned production minutes − stop minutes
  • Availability (%) = running minutes ÷ planned minutes × 100
  • Performance (%) = ideal seconds per tube × total tubes ÷ running seconds × 100
  • Quality (%) = first-pass good tubes ÷ total tubes × 100
  • OEE (%) = first-pass good tubes × ideal seconds ÷ planned seconds × 100

Inputs explained

  • Planned Production Time: Scheduled production minutes; exclude periods with no production planned.
  • Recorded Stop Time: Stops inside planned production time, including changeovers and breakdowns.
  • Ideal Time per Tube: Validated fastest achievable cycle on the same tube and process.
  • Total Produced Tubes: All tubes produced during the same planned window.
  • First-Pass Good Tubes: Tubes accepted without rework during that same window.
  • Entered OEE Target: OEE target approved for this line and reporting window.

How to use the result

  • Best suited to tube line shift Review, loss component comparison.
  • Mixed tube products need separate ideal cycles or an equivalent ideal-time total.

Current U.S. benchmarks

  • The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.

Common questions

  • Why is performance above 100% blocked? It contradicts the entered fastest achievable cycle. Check ideal cycle, counts, running time and whether parallel nests were converted to a per-tube cycle.
  • Are changeovers included in stop time? Yes, if production was planned during them. Exclude breaks or other periods with no production scheduled from planned production minutes.
  • Do reworked tubes count as good? No. OEE quality uses first-pass good tubes. Count tubes needing rework in total output, even if they are eventually accepted.
  • What does a fully stopped shift report? A planned window with all time stopped and zero produced tubes reports zero OEE, performance and quality. Production counts during zero running time are inconsistent and blocked.
