Tube wall thickness measuring systems

Tube wall thickness measurement

In order to exploit the technical potential for maximum material and energy usage to the full, the different tube manufacturing processes – regardless of the underlying forming method – require automated measuring systems.

IMS has faced the challenge of this demanding requirement successfully for more than 25 years – with a succession of measurement concepts adapted to the respective rolling units and their specific needs.


With use of IMS measuring systems you achieve:


  • Increase in material yield
  • Homogenisation of product parameters
  • Utilisation of tolerance limits
  • Reduction in downtimes
  • Elimination of manual sampling
  • Stabilisation of the rolling process


  • Determination of eccentricity and polygonality
  • Determination of wall thickness distribution around the circumference
  • Detection of thickened ends
  • Determination of the average wall thickness
  • Specification of the local wall thickness


  • Continuous acquisition of all measurement data, product parameters, and system events
  • Highest availability
  • Robust construction for use in rolling mill environments
  • System lifetime “10 plus”

»You should definitely use the opportunity to talk to us personally to find the ‘right’ measuring system for your individual needs because it is only possible to bring about the optimal decision on an IMS measuring system if we know your rolling process.«

Whether you need to monitor eccentricity after piercing, know the local distribution of wall thickness around the circumference of the hollow blank, or determine the formation of thickened ends on the finished tube, IMS has a suitable measuring system for all these and many other measurement tasks. On top of this, it is possible to build a customised compact measuring system by grouping various measurement tasks at one measuring point.

The operator of the rolling mill can use the measurement results acquired continuously along the complete length of the product and shown by the measuring system in graphic and numerical form directly for manual adjustment of the rolling parameters. In addition to this, every IMS measuring system also offers the possibility to influence the settings of the rolling mill automatically via a data interface and connected process control system. In this way it is ultimately possible to exploit the results of the IMS measuring system to the full.
