Radial nozzle scanner with probe skew

NozzleScan is a versatile, low-profile manual scanning solution developed for the inspection of nozzle welds in set-through and set-on configurations, with the option of a motorised version for automated inspection. Available in both two-axis and three-axis instrument configurations and adaptable to cover a wide range of 90-degree nozzle sizes, from 3” upwards, on ferritic and austenitic materials.

Attaching to the branch component, the innovative modular design of NozzleScan offers a variety of configurations to encode circumferential and weld offset positions as the scanner travel around the nozzle.

NozzleScan features an overhead gimballed probe holder which allows the operator to hold the transducer conventionally for a more tactile inspection. Probe skew orientation is changeable (a critical requirement for inspecting many nozzles) and can be free-running or accurately adjustable, with the additional option of being encoded as a third axis, if required. Attaching NozzleScan to the branch pipe can be achieved with either magnetic wheels for a wide range of ferritic pipe sizes, or with fixed-size clamping rings for supreme accuracy on any material. Developed to satisfy the demand for a solution, NozzleScan offers exceptional versatility to meet the inspection needs of the industry.
