- 摘要:
- 中亚天然气管道将土库曼斯坦的天然气经乌兹别克斯坦、哈萨克斯坦和中国新疆的霍尔果斯输入西二线,是目前我国最长、规模最大的能源战略通道。为了加快管道焊接施工进度,研究应用了IWM+FCAW(内焊机根焊+自保护药丝半自动焊填盖)新工艺。文章详细介绍了该工艺的研究内容、焊接评定、机组设备配置、经济分析及其在中亚天然气管道中的应用,并与传统的SMAW+FCAW(纤维素焊条根焊+自保药丝半自动焊填盖)工艺进行了比较,日焊接速度约提高一倍。
The Central-Asia Pipeline Project （CAPP） wriggles through four countries to transport natural gas from Turkmenistan to China via Uzbekistan and Kazakhstan. It becomes the longest and largest strategy energy passage in China after finally being connected with the pipeline named West -East Pipeline Project Phase II at Horgos Town, Xinjiang, China. In order to speed up the pipeline welding construction, the new welding process IWM + FCAW （inner welding machine for root pass plus flux cored arc welding for hot, fill and cap ） was developed and applied in the pipeline project. This article describes in detail the research contents of welding, welding qualification test, equipment preparation for crew, economy analysis of the new weld ing process and its application in CAPP, as well as comparison with the traditional welding process SMAW + FCAW （shield metal arc welding with high cellulose type electrode for root pass plus flux cored arc welding for hot, fill and cap ）. The welding speed is roughly doubled.2010,1(1): 53-56 收稿日期：2009-1-4分类号：TE973.3作者简介：靳红星(1967-),男,河北香河人,高级工程师,天津大学材料工程硕士,长期从事长输管道焊接与施工工作.参考文献：
