According to the safety modulus of hydraulic hose ruled by international standard, we recommend that the workingpressure 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。

Based the numerical simulation for sphere tank with defects, fracture safety assessment and stress strength verification are done under the cases of workingpressure and over pressure.
With the acceleration of the rhythm of people's lives, increasing work pressure, people want more stability and a comfortable life. Life safety of the working environment more and more attention.
