Guided Ultrasonics, Guided Wave Inspection Specialists.
Overview. Ultrasonic guided wave technology can be utilized as a screening tool to pinpoint areas of corrosion in various piping systems, providing a reduction in operating costs. Guided waves are typically used in industries such as oil and gas, petrochemical, and power generation as well as DOT agencies. By identifying
Guided wave ultrasonic testing detects corrosion damage and other defects over long 33 ft – 165 ft distances in piping. A special tool (transducer ring) is clamped around the pipe and transmits guided waves in both directions along the pipe. Reflected signals from defects and pipe features such as welds are received by the
Although guided wave testing is also commonly known as guided wave ultrasonic Testing (GWUT) or ultrasonic guided waves (UGWs) or long range ultrasonic testing (LRUT), it is fundamentally very different from conventional ultrasonic testing. Guided wave testing uses very low ultrasonic frequencies compared to those
Guided Wave Ultrasonics (GWUT) is a nondestructive examination technique that projects sound waves along pipe walls in order to detect corrosion or other damage. Guided wave ultrasonic testing is also sometimes referred to as long range ultrasonic testing (LRUT). This method is performed by placing a ring of
Guided wave ultrasonic testing (GWUT), also known as long range ultrasonic testing (LRUT), is a screening tool for rapidly testing long lengths of pipe from a single inspection point. GWUT provides 100% coverage of the pipe wall without having to remove insulation or coating. It quickly identifies areas of corrosion or
RELIABILITY OF GUIDED WAVE ULTRASONIC TESTING. Dr. Mark EVANS and Dr. Thomas VOGT. Guided Ultrasonics Ltd. Nottingham, UK. The Guided wave testing method (GW) is increasingly being used worldwide to test in- service pipe-work for corrosion. As a screening tool, GW is generally used to manage
Guided Wave Ultrasonic Technology. GUL Overview. While traditional inspection methods provide value to plant operators, many have begun condition based inspection programs aimed at bolstering their mechanical integrity and preventive maintenance programs. With this in mind, many plants have chosen to.
Guided wave ultrasonic testing is used to detect flaws, primarily corrosion, in pipes that are inaccessible for inspection by conventional means. Ultrasound is transmitted for long distances, typically 30m, and the longitudinal position of the flaws.
