摘　　要：考虑到容器静强度与载荷的不确定性,得到钢制薄壁内压容器的安全系数与试验压力系数,是创建压力容器可靠性设计理论的重要内容;根据容器静强度在最苛刻耐压试验时的许用可靠度,确定了容器在耐压试验和正常操作时的最小许用可靠度范围;得到了用于计算钢制薄壁内压容器静强度最小安全系数与试验压力系数的方法。Considering the uncertainty of vessel static strength and loads, determine safety factor and test pressure coefficient of steel thin-walled internal pressure vessel, that were important components of creating theories and methods of reliability design of pressure vessel. According to vessel static strength allowable reliability in the most harsh pressure test, the minimum allowable reliability range is defined during pressure test and normal operation. The calculation methods of safety factor and test pressure coefficient are established.
