Chain scanner

The Chain scanner solution facilitates manual inspection of pipes with outside diameters (OD) ranging from 76 mm to 965 mm (3 to 38 in.) Held by chain links instead of magnetic wheels, the scanner is well suited for weld or corrosion inspection on various material types using ultrasonic testing (UT), time-of-flight diffraction (TOFD), and phased array (PA) technologies.

The scanner offers the possibility for two-axis encoding and can inspect ferromagnetic or nonferromagnetic surfaces. The chain links help ensure a straight displacement of the scanner by eliminating steering problems. It is useful when the area around the pipe is difficult to access, as the scanner can be rotated around the pipe using the chain links.
