GB150—2011压力容器耐压试验压力取值探讨

DISCUSSION ON PRESSURE VALUE IN PRESSURE TEST FOR GB 150—2011 PRESSURE VESSELS

文章介绍了GB 150—2011相对于GB 150—1998关于压力容器耐压试验压力的主要变化,阐述了变化的原因,并给出了特殊材料较高温(材料许用应力由蠕变强度或持久强度确定)情况下的耐压试验压力计算方法。

This paper introduces the main changes in GB 150—2011vs GB 150—1998 for the pressure test in pressure vessels.It expounds the reasons for the changes and presents pressure calculation method for special material under higher temperature(the allowable stress of the material being determined by creep strength or rupture life strength).
