Exquis T4 Pro OES for a steel tube mill in Brazil

A Brazilian manufacturer of steel pipes and structural profiles commissioned an Exquis T4 Pro for material certification across carbon, alloy and stainless steel.

Product
Exquis T4 Pro Optical Emission Spectrometer
Application
Raw-material and finished-tube quality inspection against Brazilian industrial material certification requirements.

Challenge

  • Continuous production inspection demanded analytical stability over long runs, not just accuracy on a single spark.
  • Carbon steel, alloy steel and stainless steel all had to be certified on the same instrument.
  • Material certification for pipe production required trace-level results, not indicative readings.

What was installed

  • Exquis T4 Pro with a sealed circulating-argon optical chamber and high-precision CMOS full-spectrum detection.
  • Digital high-energy pre-burn excitation: a full analysis in 20–30 seconds per specimen, covering 25+ elements including C, Si, Mn, P, S, Cr, Ni, Mo and Cu.
  • Calibration set covering carbon steel, alloy steel and stainless steel raw material and finished tubular products.

Outcome

  • The instrument entered formal quality-inspection service after commissioning.
  • One instrument now certifies raw material and finished product across three steel families.
  • ppm-level trace analysis supports the material certification the mill has to issue with its pipe.

Buyer questions

What does the sealed circulating-argon chamber change?

It keeps the optical path under a controlled argon atmosphere without a vacuum pump, which holds analytical stability through long continuous inspection runs and keeps argon consumption down.

How many elements can be read in one spark?

On the T4 Pro, 25+ elements simultaneously in 20–30 seconds, including the light elements C, S and P that XRF cannot measure.
