semi-elliptical head DIN 28013KORB
product specification

Semi-ellipticall head according to DIN 28013


Dimensions

Calculation

r1 = Curvature radius

r1 = 0.8XD

r2 = Corner radius

r2 = 0.154XD

h1 = Cylindrical head height

h1 = 3s or as desired

h2 = Curvature height

h2 = 0.255da – 0.635s

H = Total inner head height

H = h1+h2
