Pressure capacity of national key scientific and t

During the "Eighth Five Year Plan" and "Ninth Five Year Plan" period, the national key scientific and technological research topic pressure vessel and pipeline accident prevention technology has made progress

this news: Recently, it was learned from relevant departments that during the "Eighth Five Year Plan" and "Ninth Five Year Plan" period, the national key scientific and technological research topic "pressure vessel and pipeline accident prevention and detection technology" has made significant progress, and the operation of various monitoring technologies has been convenient, fast and efficient

at present, China has 1228400 fixed pressure vessels in use and millions of kilometers of pressure pipelines, which are all over petroleum, chemical industry, chemical fertilizer, electric power, metallurgy, light industry, medicine and other industrial fields. Once an accident occurs, it often causes explosion, fire, poisoning, experimental pressure of 0.5 (9) MPa and environmental pollution, causing heavy losses to people's lives and state property. Countries all over the world are very strict in the control and safety management of such equipment. Our government has listed the "pressure vessel and pipeline accident prevention and detection technology" as the national key scientific and technological research topic of the "Eighth Five Year Plan" and "Ninth Five Year Plan"

the national Boiler Testing Center organized 9 systems, 46 research institutes, colleges and universities, petrochemical enterprises and testing institutions, and more than 260 experts, professors, engineers and technicians to jointly tackle key problems, and achieved a number of internationally leading and representative international advanced research results. The pressure vessel and pipeline accident prevention and testing technology has been widely used in production practice, The economic benefits of keeping the samples under regular warm test to billions of yuan have been obtained

at the 4th China Beijing international week of high tech industry and China Beijing International Science and Technology Expo, technicians can easily operate the computer to check the pipeline condition of pressure vessels, and the computer can quickly reflect defects, open welding and other problems. It is reported that using acoustic emission detection technology can not only reliably detect active defects, but also greatly improve the detection effect. The conventional inspection method requires 7 days to complete the safety inspection of pressure vessels, and the combination of acoustic emission inspection technology and routine inspection takes only 1.5 days. In addition, ultrasonic testing technology can play an advantage in the flaw detection of small-diameter, thin-walled carbon steel pipes for high-efficiency joint welds, and the accuracy error of its over standard defect safety evaluation parameters is less than 0.5 mm
