Description
The R20-S Cobra manual scanner, It can be combined with the all PA flaw detector, is used to perform circumferential weld inspections on small-diameter pipes. The R20-S Cobra scanner holds up to two PA probes for inspections on pipes with outside diameters ranging from 0.84 in. to 4.5 in.
With its slim design, this manual scanner inspects pipes in limited access areas where minimal clearance is required. Adjacent obstructions, such as piping, supports, and structures, can be as close as 12 mm (0.5 in.). This spring-loaded scanner is designed to clasp carbon steel and stainless steel pipes of various diameters using multiple links. This unique feature enables the scanner to be installed and operated from one side of a row of pipes.The R20-S Cobra scanner is characterized by its smooth-rolling encoded movement, which enables precise data acquisition. The scanner holds up to two phased array probes for complete inspection of the weld in one pass. For pipe-to-component inspections, the scanner can be configured quickly to perform one-sided inspections using a single probe.
The R20-S Cobra scanner ensures stable, constant, and strong pressure, thus providing good UT signals and precise encoding around the full circumference of the pipe.
The R20-S Cobra solution can be used with different probes, depending on the application. Phased array, TRL dual linear array, and TOFD ultrasound techniques can be performed using the following probe options:
