随着我国社会经济的发展和工业技术的进步,我国的石油天然气和石油化工工业更是飞速发展。在西气东输工程的带领和推动下,长输管道的应用越来越多、建设量越来越大,长输性的油气管道逐步走向大口径、高压力、超长度的发展方向,输送的油气量直线上升,而管道的质量对于管道长期的使用安全和油气运送顺畅来说至关重要,因此长输油气管道的各种焊接方法及应用对于保证管道运输油气的质量和效率是功劳巨大的。近年来,我国在长输管道焊接上的方法应用水平不断提高,应用了不少成熟的工艺技术。本文就是从长输管道焊接的方法及焊接方法在施工中的应用出发,对手工下向焊方法及应用、半自动向下焊方法及应用、自动焊方法及应用进行简单的介绍,希望可以对通过长输管道方法和应用的探讨,使得这些焊接方法为更多人所知道。希望长输管道焊接方法能够被更多专业人员加快改进从而获得越来越广泛的应用。
With the development of our society and economy and the progress of industrial technology, our country’s oil and gas and petrochemical industry is developing rapidly. Under the leadership and promotion of the West-East Gas Pipeline Project, the application of long-distance pipelines is increasing and the construction volume is getting larger and larger. The long-lost oil and gas pipelines are gradually moving toward the direction of large-caliber, high-pressure and ultra-long distance transportation The amount of oil and gas increases linearly while the quality of the pipeline is crucial to the long-term safety of the pipeline and the smooth delivery of oil and gas. Therefore, various welding methods and applications for long-distance oil and gas pipelines are deserving great credit for ensuring the quality and efficiency of pipeline transportation of oil and gas of. In recent years, China’s long-distance pipeline welding methods continue to improve the level of application of a lot of mature technology. This article is based on the long distance pipeline welding methods and welding methods in the construction of the application, the manual down to the welding methods and applications, semi-automatic down welding methods and applications, automatic welding methods and applications for a brief introduction, I hope we can pass Discussion of long-distance pipeline methods and applications has made these welding methods known to many people. Hope that long-distance pipeline welding methods can be more professionals to speed up improvements in order to get more and more widely used.
