Pipe inspection & dimensional control

3D Dimensional Control for pipe manufacturing

Inline 3D shaper measurement and control for diameter, ovality, straightness, length and external defect detection in seamless and welded pipe production — plus profiles and hollow profiles of various geometries.

3D Shaper — three-dimensional measuring solutions (CMMs)

Complete dimensional analysis for pipes, profiles and hollow profiles from 10 mm to 500+ mm diameter.

Our control solutions evaluate flat products for welded profiles and tubes, or extruded and seamless products. We measure in-line, contact-free and without stopping production: thickness, total and individual strip width, weld quality, shape, length, flatness, surface defects, ovality and straightness. 3D CMMs verify linear dimensions, wall thickness, straightness, shape deviation, ovality and geometric tolerances — meeting industry standards for quality and performance.

Plastic pipes

Multi-sensor configuration: a ring of profilers scans the pipe as it moves along the production line. This data is processed by our software, which calculates size parameters such as length, width and edge straightness.
