An excellent web based tool for Flat head thickness calculation under internal pressure. It also gives allowable Stress of material at a desired design temperature. This and many other tool for Pressure Vessel design as per ASME Section VIII Div. 1 would be useful for Static Equipment Engineer.

Flat head thickness calculation is based on para UG-34(c)(2) of ASME Section VIII Division 1 2011 edition code book.

Where in Flat Head thickness is given by:

t = D (CP/SE)0.5

where,
t = Cone thickness
D = Diameter
C = Factor
P = Design pressure
S = Maximum Allowable Stress at design temperature
E = Joint Efficiency
