UT Scan – The Pipeline Weld Inspection Solution
UT Scan incorporates the most advanced AUT technology for pipeline weld inspection services. Its unique, fully integrated data management process records, manages and archives the complete pipeline inspection process.
With UT Scan's advanced electronics and rugged equipment design, UT Quality has been able to simplify a complex AUT inspection process while vastly maximizing reliability of results.
UT Scan's pipeline weld inspection process offers flexibility of system utilization between mainline, tie-ins and different wall thicknesses with no delays. The weld testing procedure is transparent and consistent due to UT Scan' unique automatic auditing function which is accessible to both operators and clients.
The most recent components of the UT Scan system were selected from the best specifications available to endure the harsh conditions encountered on pipeline projects. The rugged construction of UT Scan's electronics casing ensure reliability and durability in the field. In addition, the UT Scan system fits in a small crew cab to allow multiple inspections through easy mobility.
The UT Scan Weld inspection process is outlined below:
- Following weld bevel preparation, the scribe line will be put on the pipe end (on band side). This will ultimately be used when positioning band for scanner.
- Weld will be identified by client with a unique number, prior to inspection.
- Surface area will be cleaned to provide surface condition described in section 9.1 of this procedure.
- Zero point and direction of scan will be clearly marked on pipe, as outlined in section 9.4 of this procedure.
- Weld will be cooled to meet temperature requirements as outlined in section 9.5 of this procedure.
- During or prior to cooling process band can be placed on pipe, utilizing scribed line to insure accuracy as outlined in section 9.3 of this procedure.
- Insuring that calibration meets requirements of section 11.3, and that calibration is still valid, scanner is placed on guide band, at the zero datum point as described in section 9.4.
- Scan is performed utilizing the weld ID number to identify that particular scan. (Each weld requires a unique ID).
- Evaluation is performed in real time as transducers are moved around circumference of pipe. Data is stored immediately following evaluation, and can be retrieved at any time.
- Data is analyzed immediately following scan completion; acceptability depends on client specification or code, which operator will utilize to evaluate acceptability of weld.
- Reject able welds are documented and can be reported immediately following weld scan. Defects are identified in data file and file is store.
- During data analysis process scanner technician will remove the scanner and scan band, and prepare for next weld or calibration, as required.
