erw weld Off-Line Inspection

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

Prior to inspection, the ERW pipe is loaded onto the pipe rotator by loading arms. The UT head moves along the main boom to inspect the ERW weld. The pipe remains stationary. 

Several defects can be detected:

• 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

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.

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

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