近几年来我国石油天然气企业在国民经济整体提高的带动下,也得到了快速发展,并扩大的国际市场,成为国际出口大国,这标志着我国石油天然气行业正在跨上国际轨道,我国对石油天然气的需求量不断增加西气东输等大型跨领域的工程正在大力开展,其中的环节就离不开长输管道,长输管道能减少运输中的人力物力和时间的浪费,长输管道保障了石油天然气运输的质量和效益。因此更加提高了长输管道的焊接要求,保障了焊接质量也就保障了运输工作,本文研究和探讨了长输管道的焊接技术。
In recent years, China’s oil and natural gas enterprises, driven by the improvement of the national economy as a whole, have also gained rapid development and expanded international markets and become international exporters. This indicates that China’s oil and gas industry is on the international track and that China’s oil and gas Of the growing demand for large-scale cross-sector projects such as the East-West Gas Pipeline are being vigorously carried out, of which the link is inseparable from the long-distance pipelines, long-distance pipelines to reduce transport of manpower and resources, and waste of time, long-distance pipelines to protect The quality and efficiency of oil and gas transportation. Therefore, the welding requirements of long-distance pipelines are further raised, the welding quality is ensured, and the transportation work is ensured. This paper studies and discusses the welding technology of long-distance pipelines.
