Non Destructive Testing by INSPECTECH

The InspecTech® Eddy Current System is a good on-line non-destructive testing system for weld-line inspection of thin wall tubing and can be used on fast operating mills.

​

InspecTech's Eddy Current Equipment is compact enough to fit on most mill beds, or can be mounted on the floor. Rotary stands are available to handle extremely large weld line skews.

InspecTech® Ultrasonic test systems have been at work in tube mills around the globe for over 30 years. Ultrasonic testing of welded tube is a universally recognized method, offering equal sensitivity to both inside and outside defects regardless of material thickness. Codes of practice such as ISO, API and CSA all take ultrasonic testing of welds as an acceptable, or even mandatory, method.

The Flux Leakage method of testing tubular goods has been used for many decades for full body inspection. Using this method to test weld seams in small diameter (12mm and up) tubes has, up to now, not been practical because of the difficulties in obtaining uniform magnetic fields with minimal pole piece spacing.
