摘要:
为了实现大直径厚壁焊管的国产化,宝鸡石油钢管有限责任公司联合太钢、首钢、沙钢等多家钢厂经过多轮单炉试制和多轮千吨级试制,成功开发出了国产X80级Φ1 422 mm×21.4 mm大直径厚壁螺旋/直缝埋弧焊管,并进行了多项性能检测。结果表明,螺旋焊管管体屈服强度574~681 MPa,抗拉强度653~759 MPa,-10 ℃冲击功平均值373 J;直缝焊管管体屈服强度564~627 MPa,抗拉强度641~694 MPa,-10 ℃冲击功平均值460 J;螺旋/直缝焊管-5 ℃下DWTT剪切面积平均值96%。各项性能指标均达到中俄东线X80级Φ1 422 mm×21.4 mm钢管的技术要求,说明我国已经具备了工业化批量生产大直径厚壁焊管的能力。
Abstract:
In order to realize the localization of large diameter and thick wall welded pipe, after several rounds of single furnace trial production and several rounds of thousand tons trial production, the domestic X80 grade Φ1 422 mm×21.4 mm large diameter thick wall SAWH/SAWL pipe was successfully developed, which conducted by Baoji Petroleum Steel Pipe Co.,Ltd., Taiyuan Iron and Steel Co., Ltd., Shougang Group, Shashi Iron and Steel Co., Ltd., and other steel mills, and a number of performance tests were conducted. The results showed that the yield strength of SAWH pipe body is 574~681 MPa, the tensile strength is 653~759 MPa,? the average impact energy is 373 J at -10 ℃. The yield strength of SAWL pipe body is 564 ~627 MPa,?the tensile strength is 641~694 MPa, the average impact energy is 460 J at -10 ℃. The average DWTT shear area of SAWH/SAWL pipe is 96%, various performance indicators can meet technical requirements of X80 1 422 mm×21.4 mm steel pipes used for Russia-China Eastern Pipeline, it indicated that China has the ability of industrialized batch production of large diameter thick wall welded pipe.
