UTLITE Corrosion Profiling, Corrosion Mapping and Weld Flaw Detection

  • Cost Effective & Scalable
  • Easy Intuitive Software
  • B-scan, C-scan & ToFD Inspection
  • Range Of Plug & Go Scanning Heads

The UT Lite is a portable, powerful, ultrasonic inspection system for corrosion profiling, mapping and weld inspection.

Using Silverwing’s unique dry coupled scanning technology for corrosion profiling, mapping and standard TOFD probes for butt welds, it offers distinct advantages for inspection of storage tanks, pipework and pressure vessels.

The UT Lite is designed in line with Silverwing’s philosophy of easy and fast measurement collection coupled with extensive analysis tools. This approach ensures technicians can focus on completing the job efficiently whilst capturing all the raw data to assist in reporting and Risk Based Inspection (RBI).

B-scan Software

The R-scan and Scorpion software has been designed to make life easier for the operator. The touch screen intuitive layout, with large buttons makes it ideal for site conditions, allowing the operator to conduct and analyse an inspection more efficiently.

A nominal thickness line and an adjustable reporting threshold line can be displayed over any of the B-scan views (amplitude, profile and line) to identify reportable defects at a glance and allow rapid evaluation of the complete scan. Data can be stored in pre-defined formats to make grid and tank wall scanning patterns, with direct import into CMAP. All these features are designed to make data analysis and reporting easier for the operator.

C-scan Software

Used as a follow-up inspection in conjunction with B-scan, or stand alone for C-scan mapping of small areas the system provides an easy to use 2D scan of an area. During a scan the software displays a real-time A-scan trace, C-scan image and a digital thickness measurements. The easy to use defect sizing tools make it simple for the operator to scan, analyse and highlight any areas of concern.

Recorded C-scan images can be imported directly into Windows software packages such as Word or Excel. The scan resolution is selectable to enable quick large area scans, then adjusted to give fine resolution detail as required.

ToFD Software

ToFD is now an established method for weld inspection, especially root corrosion. The simplified UT Lite system is easy to use for pipe and tank shell welds.

The software shows an active A-scan display and the D-scan image and also features several measurement tools such as lateral wave, back wall, thickness, depth, height and length for accurate measurement of recorded scans.

Reporting Tools & CMAP

All inspection and thickness measurements can be simply exported to a USB for transfer to a PC for further analysis and reporting. The exported data can be viewed in the desktop version of the software or thickness readings can be viewed in Excel. B-scan Inspection data taken from the R-scan or Scorpion can be imported to Silverwing's CMAP reporting software along with C-scan and D-scan images taken from the Thetascan or ToFD.
