| 摘 要： | 以热轧钢卷开平板为原料,采用JCOE工艺制成直缝埋弧焊管,对比分析了制管过程中成型、扩径工艺对开平板屈服强度的影响.拉伸试验发现,热轧钢卷开平板横向屈服强度均匀,纵向屈服强度偏差大.经过JCO成型后,制成的钢管相对于同位置钢板的横向屈服强度略有降低,纵向屈服强度有升有降,但总体呈上升趋势.钢管扩径后的横向屈服强度相对于...

| Abstract: | Using opening and leveling HRC,through JCOE forming process to manufacture longitudinal submerged arc welded pipe,it analyzed the influence on the opening and leveling HRC yield strength of forming and expanding processes.The tensile test results showed that transverse yield strength was uniform,while the tolerance of vertical yield strength was greater.After JCO forming,the transverse yield strength of the finished pipe was lower than that of steel plate in the same position;vertical yield strength increased or reduced,but showed upward trend in general.After expanding,the transverse yield strength was lower than that of steel plate in the same position. |
