分析了输送管管体横向拉伸试样弯曲度对屈服强度测试值的影响,从理论上初步阐明了管体横向拉伸试样的弯曲会引起屈服强度测试值的降低,并提出在相关的标准中应对管体横向试样的展平程度作出规定.
The influence of the bending degree of transverse tensile test specimen on the test value of yield strength was analyzed. It was clarified theoretically that the bending of the transverse tensile test specimen caused the decrease of the yield strength test value, Standards should be horizontal flat tube horizontal extent of the provisions.
