According to the safety modulus of hydraulic hose ruled by international standard, we recommend that the working pressure is one forth of the minimum blast pressures.
按照有关国际标准规定的液压胶管的安全系数，我们推荐的工作压力通常为胶管最低爆破压力值的四分之一。

On the other side, the proposed method can also consider the influence of the change of stress fields and pore pressure field on the minimum factor of safety by the finite element analysis.
Through the analysis of gas pulsation characteristics in reciprocating compressor and deviation in set pressure, the equation is given for determining the minimum set pressure of safety relief valve.
