摘要:
针对中俄东线天然气管道北段（黑河—长岭段）高钢级、大口径、高压力、大输量、环境温度低等特点，介绍了其环焊缝焊接工艺。从L555M 钢管的焊接性、环焊接头性能指标、环焊工艺及质量管控等方面，总结了管径1 422 mm 的L555M 天然气管道的焊接施工特点，阐述了环焊接头强度、韧性、硬度、塑性等指标要求的意义及试验检验方法，分析了焊接方法、焊接材料、焊接坡口等工艺参数的选择原则和实际应用，说明了坡口尺寸与组对精度、预热温度与道间温度、无损检测技术对焊接质量控制的影响。上述成果作为工程建设的经验性总结，可为后续油气管道工程建设的焊接施工管理提供经验。（图3，表4，参20）
Abstract:
This paper describes the girth welding technology for the north section (Heihe-Changling Section) of China- Russia Eastern Gas Pipeline concerning its characteristics of high steel grade, large diameter, high pressure, large throughput and low temperature. The construction characteristics of welding of D 1 422 mm L555M gas pipeline were summarized in terms of the weldability of L555M pipelines, The performance index of girth welding joint, girth welding technology and quality control. The significance of requirements and test methods for indicators, including the strength, toughness, hardness and plasticity of girth welding joint, were described. The selection principle and actual application of process parameters, such as welding method, welding material and welding groove, were analyzed, and the effect of the groove size, alignment accuracy, preheating temperature and interpass temperature, and NDT technology on quality control of welding was described. All of the above results are empirical summary in engineering construction, capable of providing experience support for the welding construction management in subsequent oil and gas pipeline construction.
