ERW (Electric Resistance Welded) tubes

An ERW welded tube has been constructed with a specific type of welding process, that involves both seam and spot welding. The ERW tube is constructed out of a steel strip that passes through a series of contoured rollers, that forces it into a circular shape. This process is very different compared to the manufacturing process of a seamless tube, where the tube is formed by extrusion, and no welding is needed. 

 

Measurement systems for welded ERW tubes

In our range of measurement systems for ERW tubes, you will find solutions for detecting and measuring the shape, ovality, total and local straightness of the UOE/JSAW welded tubes. 

 

LIMAB offers several measurement systems for different applications in the production of ERW tubes.

 

  • TubeProfiler
    Measurements of OD, ovality, shape and length for process control and final inspection. The TubeProfiler integrates the LIMAB PreciCura sensors.

 

  • TubeProfiler 3D
    Measurements of OD, ovality, true shape and length for process control and final inspection. The TubeProfiler 3D integrates the LIMAB ProfiCura 2D sensors which enables a complete and full scanning of the tube.

 

  • TubeProfiler S
    Measurements of OD, ovality, shape, length and straightness (total, end and local) for process control (threading and cutting operation) and final inspection according to API standards. The TubeProfiler S integrates the LIMAB PreciCura sensors.
