摘要:
采用切环法和盲孔法,对X80 1 219 mm×22 mm螺旋焊管(SAWH焊管)的残余应力进行了测试分析。结果表明:X80 1 219 mm×22 mm 螺旋焊管切环试验后管段的变形形式较为复杂,张开量较大,轴向及径向错开量亦较大,显示其残余应力较大;其外表面周向及轴向平均残余应力分别为132.1、160.9 MPa,内表面周向及轴向平均残余应力分别为-218.0、-185.5 MPa。根据测试结果,对X80 1 219 mm×22 mm 螺旋焊管残余应力的控制指标以及成型工艺参数的制定提出了建议,以期
Abstract:
The residual stress of X80 grade large diameter SAWH welded pipe is tested and analyzed through the centrehole drilling and cutring method. The results indicate that the deformation after cutring test of X80 1 219 mm×22 mm SAWH pipe is very complicated, the circumferential opening values and the axial and radial displacements are large, showing its higher residual stress. The average circumferential and axial residual stress of external surface of X80 Φ 1 219 mm×22 mm SAWH pipe are 132.1 MPa, 160.9 MPa respectively, and the average circumferential and axial residual stress of internal surface are -218.0 MPa,-185.5 MPa. The residual stress control target of X80 1 219 mm×22 mm SAWH pipe is put forward, and the suggestion to the forming process parameter is also given.
