采用切环法和盲孔法测试了规格均为1 219 mm×22.0 mm的X80钢级螺旋缝埋弧焊管（SAWH焊管）和直缝埋弧焊管中UOE焊管和JCOE焊管的残余应力，并进行了对比分析。结果表明：切环试验后，SAWH焊管的周向张开量、轴向及径向错位均较大，残余应力较高，平均残余应力为148.7 MPa；UOE焊管和JCOE焊管的周向张开量较小，无轴向及径向错位，残余应力较小，平均残余应力分别为37.0，69.3 MPa。采用盲孔法测得SAWH焊管外表面的周向和轴向平均残余应力分别为132.1，160.9 MPa，内表面的分别为-218.0，-185.5 MPa，整体残余应力水平较直缝埋弧焊管的高。建议将规格为1 219 mm×22.0 mm的X80钢级SAWH焊管残余应力的控制指标定为"切口张开间距不应大于80 mm"。

Residual stresses of spiral submerged-arc welded pipe (SAWH pipe) and longitudinal submerged-arc welded pipes of UOE and JCOE in Grade X80, φ1 219 mm×22.0 mm, were measured by cut-ring method and centre-hole drilling method. The testing results were compared and analyzed. The results show that after cut-ring test, the SAWH pipe had relatively large values of the circumferential opening, and the axial and radial displacements, indicating relatively high residual stresses; the average residual stress was 148.7 MPa. The UOE pipe and JCOE pipe had relatively small values of the circumferential opening and no axial and radial displacements, indicating relatively low residual stresses; the average residual stresses of the UOE pipe and JCOE pipe were 37.0, 69.3 MPa, respectively. The average circumferential and axial residual stresses on external surface of SAWH pipe by centre-hole drilling method were 132.1, 160.9 MPa, and those on internal surface were -218.0, -185.5 MPa, respectively. The overall residual stresses of SAWH pipe were higher than those of longitudinal submerged-arc welded pipes. It was suggested to set the control target of the residual stress of SAWH pipe in Grade X80, φ1 219 mm×22.0 mm, as "the circumferential opening values shall not be larger than 80 mm".
