The pressure pipeline is the greater danger special equipment. The pressure piping can be easily leaded to injury because of stress concentration, so it is important to detect the stress on pressure pipeline surface. This paper studies the detection principle of Barkhausen noise technique, and the relationship between the ifve characteristic values of Barkhausen noise and the surface stress of pressure pipe. Design hardware platform to detect stress, including the detection probe, signal generating module, acquisition data module and PC processing display module etc. To develop the stress detection software, which realizes the data acquisition and processing, the extraction of MBN characteristic value , the real-time monitoring of stress situation. Take the advantage of Barkhausen technology, such as fast, non-destructive etc, to realize real-time and accurate detection of stress on pressure piping surface, guarantee the quality and the safe using of pressure piping.
