Thickness of Ellipsoidal Head Under Internal Pressure:

Engineering Calculators

This calculator determines the thickness of a Ellipsoidal Head Under Internal Pressure with an internal pressure applied: Typical applications are propane tanks, compressed air storage tanks etc.

The "Joint Efficiency" reflects your confidence in the welded seam areas of the as-manufactured pressure vessel.

Note: When Thickness does not exceed one-half of the inside radius, or P does not exceed 1.25SE, use the following calculator.

Design Variables:
(P) = Design Pressure (internal)   (psi)   =     

(D) = Inside Diameter of conical portion (in.)   =
of a toriconical head at point of tangency     

(S) = Maximum Allowable Stress value   (psi) =     

(E) Lowest Joint Efficiency  (80% = .80) =     

   
   
Minimum required wall  thickness of shell (inches) =
