摘要:
拉伸试样的尺寸对拉伸试验结果的影响较大,为了提高热煨弯管拉伸试验结果的准确率,降低试验成本,结合常用热煨弯管的取样位置及GB/T 228.1和ASTM A370标准对管材拉伸试样尺寸的要求,对两种标准下不同试样尺寸进行的拉伸试验结果进行了对比分析。结果表明,热煨弯管拉伸试样尺寸采用ASTM A370要求的标距为50 mm的试样更加实用;拉伸试验时,应依据热煨弯管的不同直径,按照相应标准选用尺寸不同的试样,以提高试验结果的准确性。
Abstract:
The size of the tensile sample has great influence on the tensile test results, in order to improve the accuracy rate of hot bended pipe tensile test results and reduce test cost, combined with the commonly used hot-bended pipe sampling position and the tensile specimen size requirement in GB/T 228.1 and ASTM A370,the tensile test results of different sample size in above two standards were compared and analyzed. The results showed that the hot bended pipe tensile specimen size with 50 mm gauge length specified in ASTM A370 is more practical. In the tensile test, according to the different diameter of hot-bended pipe, choosing the sample size in accordance with the corresponding standard to improve the accuracy of the test results.
