按照SY/T 5992—2012设计的钢管静水压爆破试验设备仅限于计算钢管内的压力值，不能自动获得钢管的屈服强度及斜率。依据AS/NZS 2885.5：2012的检测方法，借助钢管静水压爆破试验设备，对试验采集到的原始数据采用Excel软件绘制成压力-进水量曲线和钢管的应力-应变曲线并进行分析，用Excel软件实现了爆破点的1/2斜率屈服强度和实际斜率的计算，结合绘图软件实现了各屈服强度的定量化求取。结果表明：用以上方法所求取的管通的各种屈服强度与实际拉伸试验得到的数据基本一致。该方法可以为按照SY/T 5992—2012设计的钢管静水压爆破试验设备扩展出屈服强度计算能力。

The hydrostatic burst testing equipment of steel pipe designed according to SY/T 5992—2012 is limited to calculating the pressure value in steel pipe, and can not automatically obtain the yield strength and slope of steel pipe. According to the testing method of AS/NZS 2885.5:2012 and with the help of hydrostatic burst testing equipment of steel pipe, the original data collected from the test were drawn into pressure-water inflow curve and stress-strain curve of steel pipe by Excel software and analyzed. The calculation of 1/2 slope yield strength and actual slope of burst point was realized by Excel software, and the quantitative calculation of yield strengths were realized by drawing software. The results show that the yield strengths of steel pipe obtained by the above method were basically consistent with the data obtained from the actual tensile test. This method can expanded the calculation ability of yield strength for the hydrostatic burst testing equipment of steel pipe designed according to SY/T 5992—2012.
