摘要:
随着天然气管道钢级、压力和数量的不断提高，为确保天然气管线钢管标准的发展和不断完善，以及天然气管道工程的安全性、完整性，提出了需进一步考虑的一些技术问题和需要进一步完善的标准细节。对高压天然气管线钢管技术标准中存在的关于化学成分、强度、断裂韧性、焊接性、埋弧焊管的焊趾角度，以及高频焊管焊缝处的壁厚减薄和焊缝拉伸性能的延塑性指标等几个技术问题进行了研究分析，并提出了改进建议。
Abstract:
With the steel grade， pressure and quatity of natural gas pipeline increasing continuously， in order to ensure development and improvement of steel pipe standard for natural gas pipeline， as well as security and integrity of pipeline engineering， it put forward some technical problems need to be considered further and some standard details need to be improved further in this article. It also studied several technical problems， such as chemical composition， strength， fracture toughness， weldability， welding toe angle of SAW pipe， wall thickness reduction in the weld of HFW pipe， and plasticity index of weld tensile property. In the end ， it put forward improvement suggestion.
