Material sampling · Scoop Surface Sampling System
SCOOPER 50
Material sampling from a service-exposed component — a small sample, virtually without a notch, with nothing cut out and no weld repair.
Portable equipment for surface material extraction without affecting the integrity of the component. The extracted sample allows chemical, metallographic and electron microscopic analysis, and determination of mechanical properties including creep and fracture toughness.

How the extraction works
01
Grinding, not drilling
A spoon-shaped tool 0.3 mm thick and 50 mm in diameter grinds away the layer between the component and the sample. The cutting edges are diamond- or CBN-coated.
02
No thermal influence
High peripheral speed, slow feed into the cut and intensive cooling. Neither the sample nor the component is thermally or mechanically affected.
03
No cutting, no repairs
A standard tensile test needs a large block cut out of the component. Here only a shallow depression with a smooth transition is left, virtually without a notch — nothing needs to be welded or repaired.
04
Automatic operation
The process is controlled by an industrial computer running dedicated software; the clamping system handles a range of component shapes.
Extraction step by step
A real extraction on a pipe during an outage — from mounting the tool to the mark it leaves behind. Sampling is done on a cooled component; a hot surface cannot be sampled.
