| FBS Pipe Inspection Services | Benfits of GW Inspection | ||||||||
FBS offers guided wave pipeline inspection services to a number of clients in the natural gas and oil, nuclear, and other industries. FBS expert technicians hold CSWIP LRUT Level II certifications and use the Teletest Focus™ long-range ulrasonic tool for low-frequency inspections. The Teletest Foucus™ is a state-of-the-art long-range guided-wave phased-array focusing technology which also utilizes well-known axisymmetric inspection approaches. Through the use of certified and experienced operators and advanced Teletest Focus™ LRUT technology, FBS is able to minimize the probability of false defect calls, improve inspection capability in coated pipes, and provide approximate defect sizing information to its customers. The guided-wave phased-array focusing technology was developed by FBS, Inc. in cooperation with Plant Integrity Ltd. and is now being used through-out the world. |

High Frequency - High frequency guided wave pipeline inspections are utilized when sensitivity to small defects is of the utmost importance. Guided waves in the frequency range of 100-800 kHz can be used to identify defects as small as 0.1% of the pipe’s total cross-sectional area. Low Frequency - Low frequency guided wave pipeline inspections are used for inspecting larger distances where sensitivity to small defects is not a main concern. Guided waves in the frequency range of 20-100 kHz can be used to inspect up to 600 ft. of pipe from a single position. Inspections in this frequency range are capable of detecting defects as small as 5% of the pipe’s cross-sectional area. |
