Olympus ERW Tube In-line Inspection System

Strip Surface Inspection

The ERW manufacturing process involves the forming of cold-rolled strips into tubular products. The quality of these strips determines the quality of the tube body. Olympus NDT offers an eddy current array inspection system for ferromagnetic and nonferromagnetic strips.

R/D Tech multiple-element eddy current technology provides maximum sensitivity and coverage for surface inspection of both sides of the strip. Take advantage of early inspection to reduce costs!

ERW Inspection Using Phased Arrays

Phased-array probes are well suited for the inspection of welded pipes. This technology offers electronic scanning, beam steering, and beam focusing. Electronic scanning of the beam across the weld area minimizes the effect of weld wandering. Beam steering and scanning allows the inspection angle to be optimized from 40 to 70 degrees for ID/OD and mid-wall defect detection. The beam focusing capability accommodates each specific thickness of pipes and tubes to be inspected. This results in higher sensitivity, a lower number of false calls, and better repeatability. Olympus NDT also offers a conventional ultrasonic solution with a multiprobe approach.

ERW Inspection Using Eddy Current Arrays

Our eddy current array ERW weld inspection system includes a DC magnetic saturation unit, two height-adjustable "V" rolls set on the pipe to control lift-off variation, and a magnetic saturation coil. Dedicated mechanics are used to minimize the effect of the butt welds through the inspection head. Segmented array probes are used and the same probe can be used to inspect tubes of various diameters.

In-Line Full-Body Tube Inspection Using Phased Arrays

The R/D Tech phased-array technology: the solution for repeatability performance and oblique defect detection.

The R/D Tech full-body solution replaces the multiple-probe approach. Its unique, patented, inspection head allows this system to meet the new industry standards for the detection of longitudinal, transverse, and lamination defects as well as to perform wall thickness measurements. The same phased-array probe can detect multiple-orientation oblique defects without the need of additional mechanical systems. The R/D Tech approach using phased arrays offers the best solution to meet the industry's new stringent requirements in terms of repeatability performance.
