摘要
对于钢管产品的拉伸试验,国标、美标以及ISO标准对试样尺寸的测量方法要求有所不同,钢管产品具有轧制特性,存在壁厚不均匀现象,壁厚的测量精度对于试验误差的控制有较大影响。对比了不同标准规定的试样尺寸测量方法,并选用两种标准方法对钢管弧形试样进行拉伸试验,对拉伸试验结果进行对比,研究了试样尺寸测量方法对钢管力学性能的影响。
For the tensile test of steel pipe products, the national standard, the american standard and the ISO standard had different requirements for measuring method of the sample size. The steel pipe products had rolling characteristics, and the wall thickness was uneven. The measurement accuracy of the wall thickness had a great impact on the control of the test error. Different standard sample size measurement methods were compared, and two standard methods were selected to carry out tensile test on the steel pipe arc sample. The tensile test results were compared, and the influence of sample size measurement method on the mechanical properties of steel pipe was studied.
