Bosen Stainless Steel, a manufacturer of 304l Precision Stainless Steel Strip, learned from the online stainless steel industry trends that from November 9 to 10, the 2022 Annual Meeting and Standard Approval Meeting of the Steel Pipe Sub-Technical Committee of the National Steel Standardization Technical Committee was successfully held in Haining City, Zhejiang Province. The planned project "Stainless Steel Seamless Steel Pipe for Instrument Pressure of Nuclear Power Plant" (20204767-T-605) issued by the National Standard Committee was edited by Zhejiang Zhongda New Materials Co., Ltd. After one year and 10 months of hard work by the compilation team, it successfully passed the examination and approval at this standard examination and approval meeting and became the first national standard led by Zhongda New Materials and independently completed the compilation.

The meeting was attended by 130 representatives from 60 units, including steel pipe manufacturers, design and research institutes, steel pipe users and third-party supervision and testing institutions. The examination and approval meeting was conducted online and offline simultaneously, presided over by Dong Li, secretary general of the steel pipe sub-technical committee. In addition, Zhongda New Materials also specially invited industry experts such as China Nuclear Power Engineering Co., Ltd., China General Nuclear Power Group Co., Ltd., and Qinshan Nuclear Power Operation Company to participate in the review meeting.

At the standard approval meeting, Chen Xiaofu, deputy general manager of Zhongda New Materials, introduced in detail the project background and standard preparation of "Stainless Steel Seamless Steel Pipe for Instrument Pressure of Nuclear Power Plant. Subsequently, the experts at the meeting answered questions about the scope of application of the standard, reference documents, technical requirements, test methods, inspection procedures, quality certificates and other chapters, and put forward suggestions. This review meeting put forward a total of 18 adoption opinions. After revision and improvement, the standard compilation is more scientific and rigorous and operable.

The examination and approval meeting also discussed the technical level of the standard "Stainless Steel Seamless Steel Pipe for Pressure-drawing of Nuclear Power Plant Instruments". The standard "Stainless Steel Seamless Steel Pipe for Pressure-drawing of Nuclear Power Plant Instruments" is technically advanced from 9 indexes such as chemical composition, non-metallic inclusion requirements, grain size, outer diameter wall thickness deviation, surface roughness requirements, hardness test, flaring/flattening test, hydraulic test and non-destructive testing.
