Geometry gauges for pipe constructions and exhaust systems are special devices used in production and quality control to ensure that pipes and components have been manufactured correctly in terms of dimensions and geometry. These gauges are particularly common in the automotive industry and plant engineering.

Main functions of these gauges:

1. Position and shape control:
   • Checking bending radii, axis paths, and geometric deviations.
   • Checking for bends and twists in the pipes.
2. Assembly and fit accuracy:
   • Ensuring that pipe segments fit exactly into brackets or adjacent components.
   • Simulating the installation position in the vehicle or system.
3. Dimensional accuracy testing:
   • Checking lengths, diameters, and connection points.
   • Use of measuring mandrels, feeler gauges, or 3D measuring systems in the gauge.
4. Weld seam inspection and alignment testing:
   • Checking whether weld seams are correctly positioned and accessible.
   • Checking the position of flanges or other connection points.
