Let’s give praise and support to the achievements in China’s chemical engineering technology and equipment. **********************[Ten Years of Progress in Chemical Engineering Equipment] A continuously updated summary thread; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** On August 10, 2012, it was reported by the National Key Laboratory of Marine Corrosion and Protection that this laboratory, using China’s first deep-sea corrosion testing apparatus developed with independent intellectual property rights, successfully completed three cycles of deep-sea corrosion tests. Today, China’s first deep-sea corrosion database was established, providing valuable technical support for the design and manufacturing of deep-sea equipment, as well as for corrosion prevention and resource development in China. Experts say that these are the first batch of deep-sea corrosion test data obtained in China, covering more than 40 types of materials and structural components such as carbon steel, low-alloy steel, stainless steel, and titanium alloys. The data include information on corrosion and aging resulting from exposure to deep-sea environments at depths of several kilometers for periods ranging from half a year to 3 years. During the 11th Five-Year Plan period, China launched research on deep-sea environmental corrosion testing facilities; this project was carried out by the **-level Key Laboratory of Marine Corrosion and Protection, which is affiliated with the 725th Research Institute of China State Shipbuilding Corporation. Research on corrosion tests in deep-sea environments is irreplaceable; moreover, there are no domestic references for the design of such testing equipment, while foreign technical information is strictly guarded and difficult to obtain ； The deep sea environment is complex with many unpredictable factors ； Challenges such as high costs and high risks. Through repeated research and by overcoming numerous difficulties, the scientists have mastered a series of key technologies, including the overall design of deep-sea corrosion testing devices and the recovery control systems for such devices. They have developed deep-sea corrosion testing devices and methods with independent intellectual property rights, and have filed 5 invention patents. Tests conducted in deep-water lakes and in actual sea conditions have shown that this device not only meets the need to deploy a large number of samples at different depths, but also ensures the safety and reliability of these samples; its deployment and retrieval are simple and easy, filling the gap in deep-sea environmental corrosion testing in China.
