小壁厚X80M钢螺旋缝埋弧焊管的研制

Research & Development of Thin Wall Thickness X80M SAWH Steel Pipe

根据克拉苏气田输气管道工程的需要,渤海装备新疆钢管有限公司对X80M钢Φ813mm×11 mm螺旋缝埋弧焊管进行了试制,详细介绍了此种焊管的试制过程和检验结果。检验结果表明,研制开发的小壁厚X80M钢螺旋缝埋弧焊管外观质量、几何尺寸、力学性能、金相及硬度、无损探伤等技术指标均符合标准要求。完全满足克拉苏气田输气管道工程(大北-克拉2段)管线对高止裂性能的要求。

For the need of Crassus Gas Field Pipeline Project, R ＆ D of X80M SAWH with a size of qb 813 mmxll mm was triM-produced by Xinjiang Steel Pipe Co.,Ltd. In this article, it detailedly introduced trial produce procedure and detection result. The results showed that all the technical indexes of the developed X80M SAWH pipe meet with standard requirements, such as appearance quality, physical dimension, mechanical property, metallographic structure, hardness, and nondestructive detection, which can fully meet the requirements to high anti-crack performance of the Crassus Gas Field Pipeline Project （Dabei -Kela 2 section）.
