Abstract: Energetic promotion of standard internationalization and in-depth involvement in development of international standards are the strategic guidelines for China’s petroleum industry to actively participate in international competition, maintain the national interests and realize high-quality development. ISO 24139—1:2022“ Petroleum and natural gas industry—Corrosion resistant alloy clad bends and fittings for pipeline transportation system—Part I: Clad bends” is the first product international standard that China has dominated and developed in the area of the oil and gas industrial pipeline transportation system. It is of the milestone significance.This standard experienced the whole process of proposal, preparation, committee, inquiry, approval and promulgation. In the development process, discussion and consultation were focused on the key technologies, such as product design, manufacture, testing and inspection. This article analyzes the framework and main requirement of the clad bend standards and summarizes the successful experience in development of the international standards. It points out that selection of topics holds the key to the international standard projects and attention should be paid to the emerging areas in which China has some advantages. It is necessary to make active involvement in the work of the secretariat of the standard committee of International Standardization Organization. In this case, China has opportunity to dominate formulation of the international standard development plan in the related areas and project management. Once the project is launched, the efforts should be focused on project management and process control.

Key words: pipeline transportation system; corrosion-resistant alloy; clad bends; research and formulation of international standards
