A cost-effective, efficient alternative to traditional ultrasonic thickness measurement location (TML) and wall thickness inspections. Inspect ferrous and non-ferrous materials with a higher probability of detection (PoD): the output, reliable, recorded, and auditable data.
Combining the R-scan handheld, dry-coupled scanner with the Swift™ ultrasonic data acquisition instrument delivers a simple to use, battery operated, portable ultrasonic inspection system ideal for applications ranging from 50 mm (2 in) up to flat plate. The software is packed with unique and intuitive features all designed to improve productivity and user experience.
The R-scan scanning head is fitted with an encoder to provide accurate positional information during an inspection. Magnetic wheels assist when scanning vertically or if inverted by minimizing the possibility of encoder slippage.
Designed to be used in remote locations and harsh petrochemical environments, Silverwing’s unique dry-coupled ultrasonic wheel probe eliminates the need for couplant or constant water supply. The probe, a dual crystal 5 MHz ultrasonic probe with a unique rolling probe face is capable of measuring material thickness ranging from 2.5 mm up to 100 mm (0.1 in up to 4 in).
Swift has a large 26.4 cm (10.4 in) non-reflective, touchscreen display. Its magnesium alloy casing is tough, rated to IP65 and designed to protect the instrument against dust and water. With a 3 mm (1/8 in) strengthened glass display, it’s the perfect instrument for harsh environmental conditions. Supplied with two lithium-ion, hot-swappable batteries the instrument allows for a full day’s work. Swift has an optional harness to support the use of the system for longer period of time. The adjustable stand, the top handle, and four corner anchor points make it practical for on-site inspections.
The Swift software controls both the Scorpion 2 and R-scan. The intuitive software is easy to use with several advanced features resulting in high-quality ultrasonic inspection data. Operators are guided through a simple process of entering the inspection details followed by ultrasonic setup. Adjustments can be made using the touch screen or hard buttons located on the Swift.
Real-time A-scan and B-scan data is displayed during the scan. Once a scan is completed the operator can analyse the results or simply save the scan and move onto the next scan. Scan analysis is made simple with active A-scan and B-scan display, placing the cursor over any part of the B-scan window shows the A-scan trace and thickness measurement for that specific location. An adjustable threshold indicator can be displayed over the profile view, helping to identify reportable defects at a glance. The full amplitude view helps to characterize wall loss, allowing for a more detailed analysis and accurate corrosion assessment.
Complete inspection data can be exported as a CSV or Excel file for statistical analyses and reporting. If preferred just A-scan and B-scan views can be exported as image files. For advanced reporting, data can be exported as a CMAP compatible CMX file. CMAP software stiches all the scans automatically based on the export values, providing a complete overview of the inspection.
A unique feature of the system is floating and tracking gates. The intelligent gates allow for a tolerance in the initial setup and deliver a more accurate inspection. The gates travel with the signal as it moves up and down, and from side to side, reducing the likelihood of incorrect or missing data, allowing for a more reliable and complete B-scan inspection data set.
Compared to traditional spot thickness measurement, the R-scan increases the likelihood of detecting corrosion by continuously records thickness measurements as the scanning head is moved over the inspection surface. The captured thickness information is displayed as an A-scan trace, a digital thickness measurement, an amplitude B-scan or a simple to understand thickness profile.
R-scan is an ideal all-rounder for inspection on tanks and pipelines. It can be used on a variety of components ranging from 50 mm (2 in) diameter up to flat surface with material thickness ranging from 2.5 mm up to 100 mm (0.1 in up to 4 in).
