Should reworked tubes count as scrap?

No. Count tubes as scrap only when they cannot be recovered. Record rework separately to preserve the difference between final retained output and first-pass acceptance.

Does total production include rejected tubes?

Yes. The denominator includes every produced tube from the same run, including scrap and rework.

What ceiling should I enter?

Use the approved allowance for your part, material and process. The calculator supplies no universal scrap benchmark.

Why can retained output differ from first-pass yield?

Retained output includes tubes recovered through rework. First-pass yield counts only tubes accepted without rework.

Tube, Pipe & Profile Forming calculator

Tube Scrap Rate Calculator

Find the percentage of produced tubes that became unrecoverable scrap. Use the reject count, total production and the scrap ceiling for the same run.

What this calculator does

Measure irrecoverable tube scrap against your entered run ceiling.

Formula used

Scrap rate = scrapped tubes ÷ total produced × 100
Ceiling headroom = scrap ceiling − scrap rate
Retained tubes = total produced − scrapped tubes

Inputs explained

Tubes Scrapped: Unrecoverable tube rejects recorded for this run.
Total Tubes Produced: All good and rejected tubes from the same run.
Scrap Rate Ceiling: Approved scrap allowance for this run or part.

How to use the result

Best suited to run scrap Review, material lot comparison.
Piece counts do not measure the mass or financial value of scrap. Retained tubes include reworked output and do not represent first-pass acceptance.

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.
