Pressure vessel calculation

It must have happened to you that you are in doubt whether the pipe can withstand the set pressure or you have a steel tank that you are not sure about how much load it can stand ?
This modest calculator calculates the following based on the entered parameters: inner and outer diameter and working pressure:

• Circulation stresses at 3 points of intersection (internal, central and external)
• Radial stresses at 3 points of intersection
• Elastic deformations due to stress change (in 3 points)

• According to the theorem of maximum stresses
• According to the theorem of maximum tangential stress
• According to the theorem of maximum deformation work
