Guided Wave is an accurate and reliable NDT inspection method to detect corrosion. Amerapex is an industry leader in Guided Wave testing. Call Us (713) 263-0900 2950 North Loop West Suite 1100 Houston, Texas 77092 . About News Locations Careers . Asset Management. The guided waves can travel in the circumferential or axial direction and are sensitive to thickness changes (corrosion losses) on entire volumes of pipe (internally and externally). To assess the location and extent of corrosion damage, IRISNDT operators use EMAT guided wave ultrasonic wave arrival time (velocity change) and amplitude information. guided wave Ultrasound (GWT) Our Advanced NDT Group utilizes Guided Wave Testing (GWT) to remotely analyze assets for corrosion and flaws over long distances, without the need for shut-down. GWT can be used for evaluation of corrosion damage and other defects in oil and gas pipelines, chiller systems, fire repression piping, and solid rods. Best NDT,API, ASNT training in Trichy Guided wave testing on piping uses controlled excitation of one or more ultrasonic waveforms that travel along the length of the pipe, reflecting from changes in the pipe stiffness or cross sectional area. A transducer ring or exciter coil assembly is used to introduce the guided wave into the pipe and ugw inspection of pipeline has many advantages; from a single test location the system 'guided ultrasonic waves' can be directed in opposing direction along the pipe length testing up to several metres in length (dependant on pipe dimensions/condition), facilitating the inspection of long runs including ('insulated' and 'buried') pipeline, to … Guided Wave is a technique which uses low frequency sound waves to flood thin wall material and then reflect back at interfaces such as cracking or corrosion/pitting. The guided wave technique is to be used as a screening tool only as remaining wall thickness measurements cannot be achieved. Level II Guided Wave Technician - Job. Location: NDT.org : Industrial and NDT Jobs : NDT Inspection Jobs : Posted: 1/24/2022. The Level II Guided Wave Technician is responsible for, but not limited to: - Set up and calibrate nondestructive testing equipment - Conduct tests to ensure quality or detect discontinuities (defects) using Guided Wave Guided waves provide a possible solution to this problem and permanently-installed guided wave pipe inspection systems are now available. The sensitivity obtained with a permanently-installed system is significantly better than that in a one-off test as baseline subtraction can be employed. However, this is far from trivial as it is necessary This Webinar includes an introduction to Guided Wave Inspection Theory and Technology. Attendees will learn about the powerful benefits of this solution and its advantages and limitations for pipe inspection as a screening tool and part of an overall NDT program. The basic steps of performing Guided Wave in the field from deploying to reporting will be reviewed for a real perspective of what GWT inspection services are a long-range Advanced Non-Destructive Testing (ANDT) solution for asset corrosion detection, helping to prevent critical production losses and crucial asset damage. GWT Technology. Guided Wave UT is used to rapidly inspect pipelines, piping systems, and other assets with minimal insulation removal.
