摘要:
为了全面了解日本第一条X80钢级高压输气管道工程的建设情况，从管道设计思路、管材制造、环缝焊接工艺及施工等方面进行了总结和分析。由于该管线安装在城市地区，设计要求具有极高的安全性和抗震性能。为了保证管道安全，将最大工作压力下的许用环向应力限制在222 MPa以下；工程用板材成分设计中严格控制Ti/N比，轧制采用了动态加速冷却技术，保证大批量高效生产的钢板满足钢管技术规范的要求；钢管采用了160 ℃的低温外涂层工艺，各项力学性能均超过了API标准的基本要求；环缝焊接采用与母材完全高强匹配的焊接材料，研发了性能和无损检测质量优良的机械GMAW焊接工艺。该管道各项技术可为高强度管道的建设提供借鉴。
Abstract:
In order to fully understand the construction situation of the first X80 steel grade high pressure gas transmission pipeline project in Japan, the pipeline design ideas, pipe material manufacturing, girth welding process and construction and other aspects are summarized and analyzed. It is found that the pipeline is installed in urban areas and the design requires high safety and seismic performance. In order to ensure pipeline safety, the allowable circumferential stress under the maximum working pressure should be limited below 222 MPa; Ti/N ratio is strictly controlled in the composition design of sheet metal used in engineering. New dynamic accelerated cooling is adopted in rolling to ensure that the steel plate produced in large quantities and efficiently meets the requirements of steel tube technical specifications. The steel pipe adopts the low-temperature external coating process at 160 °C, and the mechanical properties exceeded the basic requirements of API standard. The girth welding adopts the welding material that is fully matched with the base metal, and the mechanical GMAW welding process with excellent performance and NDI quality is developed. The technologies of this pipeline can provide reference for the construction of high-strength pipelines.
