The HSMT-Flex™ is intended for one axis encoded inspection of circumference welds on pipes of 4.5 in. OD (114.3 mm) and greater. The scanner comes equipped with four probe holders but can be mounted with a total of eight probes with optional probe holders. Mounted probes can be either phased array or conventional UT for most efficient inspections.
The major characteristic of the scanner is its capacity to bend in the center. This allows the scanner to fit on smaller pipes and also to bring the force of the spring-loaded arm in the radial direction of the pipes for better stability of the wedge, and therefore, optimum data acquisition. For the same reason, optional probe holders that are installed on the outside of the scanner can also pivot.
The HSMT-Flex also allows one of its side frames to slide. This feature allows having the probes mounted on the outside of the scanner. This provides a configuration that is well-suited for hard-to-reach places such as pipe-to-component welds.
