speed. By offering direct, absolute measurements unaffected by
temperature or pipe motion, it delivers reliable data where tradi-
tional gauges cannot. When paired with an outer-diameter gauge,
the system provides a complete real-time picture of pipe geometry,
allowing operators to fine-tune process parameters immediately
and maximize yield from each coil.
Recent installations of the Lut 2.0 in an ERW plant show how its
data-driven interface transforms production oversight. The operator
display presents wall thickness, outer diameter, and a “production
efficiency ratio” that compares the achieved thickness to the target
(see figure). Green, orange, and red color codes make tolerance
status instantly visible, while blue bars indicate variation along the
pipe. The goal is to keep both the average value and its spread with-
in the green zone, minimizing material use without risking non-com-
pliance. A polar chart complements this view, showing where thick-
ness deviates around the pipe circumference, helping operators
balance quality and efficiency through precise mill adjustments.
The business implications are clear. Real-time measurement elim-
inates the guesswork and over-compensation that traditionally
undermine welded pipe production. Tecnar’s Lut 2.0 enables mills
to operate closer to their true process limits, reducing raw material
costs, improving product uniformity, and increasing throughput.
Beyond being a precision instrument, the Lut 2.0 represents a shift
toward modern, data-driven manufacturing, where every meter of
pipe and every kilogram of steel is used to its fullest potential.
