    Development and Property Analysis of Hi-performance Gas Transmission Linepipes under High Pressure and Axial Strain（Part Ⅱ）

    • 摘要: 近50年來,天然氣的消耗量大大增加,并且會(huì)繼續(xù)增加以降低主要能源的CO2排放量。隨著天然氣供應(yīng)量的增加,為保證其輸送的經(jīng)濟(jì)性和安全性,開發(fā)了高強(qiáng)度大直徑焊管,并已成功應(yīng)用在全球多個(gè)地區(qū)(如北極地區(qū)、地震帶和深海海域)。天然氣需求的增加對(duì)長(zhǎng)距離輸送管線用鋼管提出了新的要求,為此,研究了更為惡劣環(huán)境下承受高壓和軸向應(yīng)變的高性能鋼管;分析了所開發(fā)的高壓輸氣管線用高品質(zhì)鋼管的性能;探討了承受軸向應(yīng)變鋼管的進(jìn)一步開發(fā)。

       

      Abstract: Natural gas consumption has been remarkably increased over the last 50 years, and is expected to keep going up for the purpose to reduce CO2 emission from primary energies. Along with the increase of natural gas supply, economic and safe transmission thereof needs to be ensured. Accordingly, high strength and large diameter welded pipes have been developed, and applied successfully, in various places throughout the world, including the arctic region, the seismic areas and the deep sea areas. Further increase of gas demand is expected, and additional requirements are put forward to long distance pipelines. Therefore, high performance pipes under high pressure and axial strain are studied for more stringent environment. The properties of the high quality pipes as developed for high-pressure gas pipelines are summarized. And finally, the possibility of further improvement of steel pipes for axial strain is discussed.
