摘要
通过对陕京二线管道工程用X70级管线钢规定总伸长应力值 (Rt0. 5 )在测量过程中所产生的误差进行分析,指出了加载速度、试样形状尺寸、试样偏心、试样不平度、试验机力值偏差以及人为和设备等因素对测量误差的影响,提出了减小误差的方法。
It is pointed out that the measuring tolerance influenced by the power value tolerance of accelerating speed,test specimens shape dimensions,specimens eccentricity,specimens unevenness,tester as well as man-made and equipment,etc.And put forward the method of reduce tolerance through analysis of tolerance occurred during measuring specified total elongation stress value(R t 0.5)of!X70 line pipe steel for Shaanjing 2nd pipeline project.
