How can foreign-grade materials manufactured in China be used under the new capacity regulations?

There are currently three such methods: 1. The container manufacturing factory of ours conducts a review and submission in accordance with clause 1.9； 2. The material manufacturing enterprise shall submit an evaluation application in accordance with Article 1.9 ； 3. Follow the old regulations and wait for item 2 to be completed. I would like to ask everyone if there are any other methods? ? ? That is, according to the new capacity regulations, are there any simplified methods or operations that can be completed in a short time? ? ?

Opinions on the Implementation of the \"Regulations on Safety Technical Inspection of Fixed Pressure Vessels\" (Quality Inspection Special Letter [2009] No. 89) I. Transition Period for the New Regulations Considering practical issues such as the time required by pressure vessel design and manufacturing units to update their quality system documents, train their staff, and obtain new certificates, the transition period for the new regulations has been set from December 1, 2009, to November 30, 2010. During this period, those who meet the requirements should comply with the new capacity regulations ； For those facing genuine difficulties, the design unit may use the old capacity regulations for design, and the manufacturing unit shall produce according to the specifications in the design drawings; however, the manufacturing must be completed within the transition period. During the period when old and new appearance regulations coexist, they must not be used interchangeably in the production of the same product. ...... (V) Manufacturing and use of overseas materials. When manufacturing pressure vessels from materials of foreign grades, the provisions of Article 2.9 of the new pressure vessel regulations shall be followed. Enterprises that manufacture materials of foreign standard grades shall undergo a technical evaluation in accordance with Article 1.9 of the new regulations. Our bureau has entrusted the Boiler and Pressure Vessel Standards Committee to carry out this evaluation, and relevant enterprises can submit their evaluation requests directly to the committee.

The (new regulations) specifically include provisions regarding foreign materials~~ It seems that such materials must go through an evaluation process before they can be used, and the requirements are quite strict~~ I think it’s done **to support domestic products**, haha

hehe Some people think it’s an opportunity to make money for the evaluation committee

Conducting a technical review of material applications is something that steel mills should do. What the pressure vessel manufacturing unit needs to do is conduct re-inspection of the materials.

I am not very familiar with the design and manufacturing of pressure vessels, so I have the following question: If domestic-made materials are used, why choose foreign brand names? For conventional foreign-brand materials, there are corresponding domestic brand names available in China. Is it due to inventory issues? Or is it because exporting requires the use of foreign brand names? I really hope everyone can clarify why designers choose materials from foreign brands.

I’ve contacted the steel factory, and they said the process is complicated and they don’t know how long it will take. Our product drawings have already been modified in accordance with the new regulations; what’s left now is the review phase. The products are held up by the municipal inspection authorities, who won’t allow us to proceed. So I’m asking if anyone has any good suggestions, other than modifying the drawings again to meet the old regulatory requirements (the inspection authorities say that would be sufficient)

Please call Qin Xiaozhong to ask; after all, it’s the bosses who have the final say. Hehe. . .

It can also be made using materials produced abroad, or domestic materials can be used as substitutes.

Please check the website for phone numbers; I had them written down somewhere but can’t remember where. Sorry. Qin Xiaozhong was born in November 1940, from Zhaoyang Town, Xinghua City, Jiangsu Province. Former Deputy Chief Engineer of China General Machinery Engineering Corporation, professor-level senior engineer. Vice President of the Chinese Society of Pressure Vessels for the 4th and 5th terms, Chairman of the Materials Committee of the Chinese Society of Pressure Vessels for the 1st to 5th terms, Executive Director of the China Steel Structure Association, President of the Container and Pipeline Association of the China Iron and Steel Association, Deputy Chairman of the Design Subcommittee of the National Technical Committee for Standardization of Pressure Vessels for the 1st to 3rd terms, Advisor to the National Technical Committee for Standardization of Boilers and Pressure Vessels, and leading expert in materials. 　　In 1951, he attended Xinghua Middle School. In 1957, he was admitted to the Metallography department of Xi’an Jiaotong University. In 1962, he was assigned to the General Machinery Research Institute under the First Ministry of Machinery, where he held successive positions such as technician, engineer, team leader, and deputy director of a department. In 1981, he transferred to China National General Machinery Engineering Corporation, where he served as engineer, senior engineer, professor-level senior engineer, deputy director, director of a department, deputy director of a division, and deputy chief engineer, among other roles. 　　In the 1960s, research, promotion, and application of container steel series in our country began. In the 1970s, systematic studies were conducted on foreign steel grades used for containers as well as the development trends of new steel types. Timely proposals were made to initiate, organize, or plan research projects for the development of new steel grades, and joint efforts were undertaken with relevant organizations to carry out application research on high-strength steels, low-temperature steels, and medium-temperature hydrogen-resistant steels for use in containers. Through over 40 years of hard work, a series of steel grades for containers with Chinese characteristics has been developed, among which the low-weld-crack-sensitivity low-temperature high-strength steel and the -70°C low-temperature steel are at the international leading level. Responsible for or involved in the development of over 40 standards for containers and steel materials. Over 40 years of research on steel for pressure vessels, industry promotion, and standard development have made significant contributions to raising the technical level and safety of pressure vessels in China, as well as to accelerating the localization of steel used in such vessels. More than 50 papers have been published in journals such as the Acta Metallurgica Sinica and Pressure Vessels, and he has served as chief editor of the World Handbook of Steels for Pressure Vessels and Steels for High-Performance Pressure Vessels and Pressure Pipes. He has also contributed to the compilation of over 10 academic works, including the Handbook of Mechanical Engineering, the Handbook of Alloy Steels, and Materials for Mechanical Engineering. It has won 16 awards for scientific and technological progress at the ** level and at the provincial/ministerial level, including two second prizes for scientific and technological progress. In 1978, she was awarded the title of Advanced Worker in Science and Technology of the National Machinery Industry, and in 1994, she was granted the title of Outstanding Young and Middle-Aged Science and Technology Expert at ** level. China’s first group of individuals to receive the **special allowance** issued by the State Council.
