Forum Technical Discussions Re: High Temperature Thickness Measurements Posted by: Sang Kim (PID_3469), E-mail: Address, on July 29, 2008 at 01:49 : In Reply to: High Temperature Thickness Measurements posted by : Collin Maloney , E-mail: Address, on July 28, 2008 at 07:30 : If you want to find the wall thinning in elbow part or corrosion in pipeline, you can use high-temperature guided wave probe that works at 300 deg C and is permanently mounted onto inaccessible pipe locations. That system and probe are commercially available. Please refer this website for more information ( http://www.gwanalysis.com/guided-wave-monitoring.html). If the corroded region is located inside pipe support, you can use plate probe for generating ultrasonic wave along circumferential direction and monitoring the defect growth of pipe inside the pipe support. For the measurement example of guided wave monitoring of wall thinning using the guided wave probe, please refer the paper named “Guided Wave Pipe Inspection and Monitoring System,” that is available this website (http://www.mhi.co.jp/en/technology/review/pdf/e423/e423138.pdf). If you need more information, please email me. Sincerely, Sang ----------- Start Original Message ----------- : Hi, I'm looking into availability of commercially produced ultrasonic probes capable of being permanently mounted onto inaccessible pipe locations. They need to be connected to either a flaw detector or datalogger. The pipe is operating at 170 deg C and the inspection interval is monthly. ------------ End Original Message ------------ Follow Ups: Post a Followup: Name: E-Mail: Subject: Comments: ----------- Start Original Message ----------- : If you want to find the wall thinning in elbow part or corrosion in pipeline, you can use high-temperature guided wave probe that works at 300 deg C and is permanently mounted onto inaccessible pipe locations.
