Should running time include coil changes?

No. Enter coil changes as stops within scheduled production time. Include only the minutes producing tube in running time.

Why are there two average speeds?

Running speed measures production pace. Scheduled average speed spreads the same footage over the full scheduled window, including stops.

Should I subtract rejected footage?

Use one consistent footage basis. For shippable throughput, enter accepted finished footage and keep both time entries from that same window.

Can the measured speed exceed my target?

Yes. A target is your planning threshold, not a physical maximum. Verify weld quality and the approved process settings before adopting the higher rate.

Tube, Pipe & Profile Forming calculator

Welded Tube Line Speed Calculator

Find the footage rate your tube mill delivered while running and across the scheduled window. Enter finished footage, logged running minutes, scheduled minutes and your target running speed.

What this calculator does

Measure tube mill footage per running minute and compare it with your entered line speed target.

Formula used

Running speed = finished footage ÷ running minutes
Scheduled average speed = finished footage ÷ scheduled minutes
Scheduled hourly output = scheduled average speed × 60
Observed uptime (%) = running minutes ÷ scheduled minutes × 100
Speed gap = running speed − target speed

Inputs explained

Finished Tube Footage: Measured finished tube length from the same production window.
Mill Running Time: Logged minutes making tube; exclude line stops.
Scheduled Production Time: Scheduled production minutes including stops, excluding unscheduled breaks.
Target Running Speed: Running footage rate entered in your approved production plan.

How to use the result

Best suited to mill shift Review, coil change loss review.
The average does not establish an approved weld speed or remove defect footage automatically.

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.
