这个页面有详细的计算器，你可以把数据填入进行计算
我帮你算了一下，大概厚度要做到：2-3个厚以上就可以安全使用了。
具体的计算公式如下：
Equation:
P = (2*S*T)/((O.D.-2*T)*SF) 计算公式。
Where:
P = Fluid Pressure (psi) 压力（单位psi,1MPa = 145psi）
T = Pipe Wall Thickness (in) 厚度 （单位 in,1 in = 25.4mm）
O.D. = Pipe Outside Diameter (in) 外径（单位 in）
SF = Safety factor (General Calculations 1.5 10, Use 1 For Bursting Pressure) 安全系数。
S = Material Strength (psi)Ultimate Tensile strength or Yield strength can be used.
Ultimate should be used to determine the bursting pressure.Yield can be used for estimating pressures at which permanent deformation begins. 材料的机械强度
