K-secal small help tool calculates the Torispherical Head Blank Diameter. Diameter is required for the fabrication of head from plate. Along with diameter this tool also calculates head blank weight and Volume. For weight you have the option to select different type of metals. Select FPS unit to calculate diameter in “inch”.
This tool also has the option to select different type of heads (2:1 Ellipsoidal and Hemispherical) thus instantly comparing the data between three different type of head.
For torispherical head the knuckle radius =0.6 times the vessel diameter has been considered.


Following formula has been used for calculating the torispherical head blank diameter:


For plate thickness less than 25 mm / 1.0 inch

Blank Diameter = D + (D/42) + (2*S.F)+ ((2/3) * Kr)

For plate thickness equal or more than 25 mm / 1.0 inch
Blank Diameter = D + (D/42) + (2*S.F) + ((2/3) * Kr)+ thk

where,
D = Outside Diameter of Torispherical Head
S.F. = Straight Face
Kr = 0.06*D = Knuckle Radius
thk = Thickness of Head
