WASHINGTON — FBS Inc., a manufacturer of ultrasonic guided wave technology, has received a $299,960 contract from the U.S. Environmental Protection Agency (EPA) as part of the Small Business Innovation Research (SBIR) program.

The company will use the funds to further develop technology that uses ultrasonic guided waves to detect defects in water pipelines.

During the Phase 1 portion of this project, the company demonstrated the feasibility of axial crack detection using circumferential guided waves and defect detection in a concrete-lined pipe using axial guided waves.

In Phase II, FBS will focus on the development of two prototype systems. One is a circumferential guided wave tool that is capable of detecting axial cracks by traveling through the inside of a steel water pipe. The other combines guided wave focusing techniques with the recently developed magnetostrictive sensors for defect screening of concrete lined water lines.
