结合高性能油气输送管的发展方向,分别介绍了超高强度钢管、低温环境用钢管、腐蚀环境用管、大应变钢管以及深海油气开发用钢管的需求、成分与力学性能要求、国内外研发与工程应用情况等。与国际领先水平相比,我国高性能油气输送管的技术水平和质量水平尚有一定差距,建议国内生产企业和科研院所开展联合攻关,不断提升超高强度钢管、大应变钢管及深海油气开发用钢管的性能稳定性,并研究解决低温环境用钢管韧性指标的确定以及腐蚀环境用管的材料选用等问题。
Combined with the development trend of high performance oil and gas pipelines, the requirements, composition and mechanical properties of super high strength steel pipe, low temperature environment steel pipe, corrosion environment pipe, large strain steel pipe and deep sea oil and gas development pipe were introduced respectively. Project application and so on. Compared with the international advanced level, there is still a gap between the technical level and the quality level of high performance oil and gas pipelines in our country. It is suggested that joint efforts should be made by domestic manufacturers and research institutes to continuously improve the development of ultra-high strength steel pipe, large strain steel pipe and deep-sea oil and gas Steel pipe performance and stability, and to study and solve low temperature environment with toughness of steel pipe to determine the indicators and the corrosive environment with the tube material selection and other issues.
