The research team has organized more than 10 organizations to undertake the national science and technology as well as relevant support programs as well as a series of subjects sponsored by the former Ministry of Labor and the General Administration of Quality Supervision (AQSIQ), so as to research acoustic emission testing and assessment techniques for special equipment (such as pressure vessel and pressure piping) and develop relevant equipment. So far, 7 research achievements have been made, with wholly technological breakthrough in the acoustic emission testing of pressure equipment. (1) From 1986 to 1989, "Research on the Application of Acoustic Emission to the Inspection of Pressure Vessels in Use", a subject of the former Ministry of Labor; (2) From 1992 to 1995, "Acoustic Emission Testing and Monitoring Assessment Technique for Hazardous Defects of Pressure Vessels in Service as Well as Relevant Equipment Development", a national major science and technology subject during the "Eighth Five-year Plan"; (3) From 1996 to 2001, "Research on Key Techniques for the Defect Testing and Monitoring of Pressure Piping", a national major science and technology subject during the "Ninth Five-year Plan"; (4) From 2000 to 2002, "Development of Safety Testing Instrument for Boiler Piping" - "Research on Multi-channel Digitalized Acoustic Emission Testing and Analysis System", a national major science and technology subject during the "Ninth Five-year Plan"; (5) From 2001 to 2006, "Research on Key Techniques for the Online Inspection and Monitoring of Pressure Vessels", a national major science and technology subject in the "Eleventh Five-Year Plan"; (6) From 2006 to 2009, "Research on New Methods and Key Techniques for the Leakage Testing of Fluid Pipe Network", a major project sponsored by national natural science fund; (7) From 2006 to 2009, "Research on the Leakage Point Location and Testing of Embedded Gas Piping and Relevant Equipment Development", a subject of national science and technology support program during the "Eleventh Five-Year". Some key technical parameters in this Part mainly refer to research achievements of the above-mentioned projects, on-site acoustic emission testing experience of several special pressure equipment as well as testing data analysis and acoustic emission location source re-inspection results.
