摘要：A novel Brillouin Optical Time Domain Analysis sensors, BOTDA(R), has been developed, which can monitor steel corrosion in concrete structures and various insulation structures. The application of distributed BOTDA(R) technology in heating supply pipe corrosion detection is discussed in this paper. According to the characteristics of derictly buried heating supply pipe, we have designed the optical fiber corrosion sensors for the prefabricated pipe, and the sensors were arranged in the junction of pipe section. Accelerated corrosion tests were used to demo the acid soil environment. Quantitative evaluation was derived formula for steel pipe corrosion. ? 2013 by IFSA.
