摘要:
随着油气管道输送量和压力的不断升高，钢管管径和壁厚不断增大，管线钢材料的钢级和韧性不断提高，传统单层埋弧焊管的制造难度和成本不断加大。受双金属复合管结构和多层超高压容器的启示，设计了一种大直径双层埋弧焊管，拟从结构上提高钢管的承压能力，从而提高管道的输送能力。分析表明，双层埋弧焊管作为一种新型的管道钢管有许多结构特点，但是要在油气管道中应用还有诸多技术问题需要解决。
Abstract:
With demanding quantity and pressure increase of gas and oil transmitting pipeline,pipe diameter,wall-thickness and material toughness in pipeline steel were enhanced,the production difficulty and cost of traditional single layer SAW production were added.Learning from double metal complex structure and multilayer over high-pressure container,double layer SAW with large diameter was designed,this will enhance pipe holding pressure capacity,so it can improve pipe transmission capacity.The analysis results showed double layer SAW pipe as a new kind of pipeline steel pipe has many characteristics,but many technology problems need to be solved in gas and oil pipeline application.
