| 摘 要： | API SPEC 5L《管线钢管规范》和ISO/DIS 3183《石油天然气工业管线输送系统用钢管》明确提出了在钢级不高于X90时,使用Rt0.5作为材料的屈服强度;而当钢级高于X90时,Rp0.2则更适用于材料的屈服强度。但在管线钢及管线钢管实际的生产检验过程中,对于X65,X70和X80钢级的厚壁管线钢材料,由于受外在因素的影响,其测试结果有很大离散性,甚至已经严重影响到对结果的判定。探讨了采用Rp0.2代替Rt0.5进行管线钢屈服强度测量的可行性,为有效消除外在因素对屈服强度试验结果的影响提供理论依据。 |

| Abstract: | In API SPEC 5L Specification for Line Pipe and ISO/DIS3183 Petroleum and Natural Gas Industries--Steel Pipe for Pipeline Transportation Systems, it put forwardR_t0.5 can be used as yield strength while pipeline steel grades ≤X90, and for grades〉X90, R_P0.2 can be applied. However, the yield strength test results of X65, X70 and X80 grades pipeline steel with heavy thickness are seriously scattered due to the external factors; even it greatly affects judging result. In this paper, the feasibility of using R_P0.2instead ofR_t0.5 to measure the yield strength of pipeline steel was studied, which provides a theoretical basis for eliminating the influence of external factors on the yield strength test results. |
