- 摘要:
输气管道和工业管道在功能、属性和技术上的区别往往被忽视,通常人们会误认为工业管道较输气管道在技术上更为复杂,要求上更为严格,因而在管理上可能对该两类管道的类别划分不清。分析可知，输气管道与工业管道虽然同属压力管道,但是两者功能和属性不同,所处自然环境及社会条件也不同,因此在设计、材料选用、焊接施工及生产运行的各个环节都有重大区别,主要体现在管道钢管壁厚计算公式、材料选用及材料体系、夏比冲击韧性试验温度及冲击功合格值、标准规范体系和焊接施工上。纵观美国ASME B 31.3《工艺管道》与ASME B 31.8《输气和配气管道系统》的编制历史变迁可知,输气管道与工业管道属于不同类别各自独立的管道体系,在技术上和管理上都应该立足于这个原则开展生产运行和管理工作。
Although gas pipelines and industrial pipelines are both pressure pipelines, because of their different functions, attributes, natural environment and social conditions, all links from design, selection of materials, welding construction to production and operation are different, including the calculation formula of the wall thickness of the steel pipe, the material selection and material system, the Charpy impact toughness test temperature, and the qualified value of the impact energy,the standard specification system and welding construction. The historical changes in the compilation of ASME B31.3 and ASME B31.8 in the United States have also inspired us that gas pipelines and industrial pipelines belong to different types of independent pipeline systems. Operation and management shall be carried out on this principle.
