Pipeline Inspection with Guided Waves

Updated: Feb 27, 2020

TECHKNOWSERV specializes in the nondestructive testing of pipelines with long-range ultrasound (LRUT). Under ideal conditions, guided wave ultrasonic testing (GWUT) technology may be used to inspect up to 1000 feet (300 meters) of pipe from a single sensor position or up to 4000 feet (1.2 km) in one day. The actual inspection range depends on the type of pipe coating, degree of corrosion present in the pipeline, number of elbows, and whether or not the pipe is aboveground or underground. Guided wave testing (GWUT) technology may be applied to thin- and thick-walled pipe, with diameters ranging from 1” to 60”, rapidly and economically. Use reliable engineering data to assess exactly where your pipeline needs follow-up nondestructive testing such as long range ultrasound testing or visual inspection.

Benefits include:

››Rapid screening of long lengths of pipe

››100% of pipe wall is inspected

››Detection of corrosion in insulated and buried pipelines
