近50年来,天然气的消耗量大大增加,并且会继续增加以降低主要能源的CO2排放量。随着天然气供应量的增加,为保证其输送的经济性和安全性,开发了高强度大直径焊管,并已成功应用在全球多个地区(如北极地区、地震带和深海海域)。天然气需求的增加对长距离输送管线用钢管提出了新的要求,为此,研究了更为恶劣环境下承受高压和轴向应变的高性能钢管;分析了所开发的高压输气管线用高品质钢管的性能;探讨了承受轴向应变钢管的进一步开发。
In the last 50 years, natural gas consumption has increased significantly and will continue to increase to reduce CO2 emissions from major energy sources. With the increase of natural gas supply, high-strength and large-diameter welded pipes have been developed to ensure the transportation economy and safety and have been successfully applied in many regions of the world, such as the Arctic, the seismic zone and the deep-sea. The increase of natural gas demand puts forward new requirements for the steel pipelines for long-distance conveying pipelines. Therefore, high-performance steel pipe subjected to high pressure and axial strain under more severe conditions has been studied. The high-quality gas pipelines developed with high quality The performance of steel pipe; discussed the further development of axial strain steel pipe.
