erw weld Off-Line Inspection

SOFRATEST provides Ultrasonic inspection solutions for off-line weld inspection of ERW pipes, outside the production line. 

Discover the main application principles:

• Internal/External longitudinal and transverse defects detection in the weld (several configurations of probe arrangements available: I, K, X)
• Lamination defects detection in the Heat Affected Zone (HAZ), in the pipe body, and in the ends of the pipe
• Midwall weld defects detection
• Loss of coupling detection

SOFRATEST’s designed inspection head perfectly adapts to the different curvatures and diameters of the pipes.

The inspection head can slide to a standard pipe positioned on a calibration support to perform calibration.

Phased Array sensors can be seamlessly integrated into the SOFRATEST system.

The inspection head can automatically adjust itself in case of deviation from the weld area thanks to the presence of a pilot line tracking system.

An additional function allows the rotation of the ERW pipes, resulting in a complete inspection of the pipe body.

A paint marking is available for defects detection and loss of coupling.
