Flat Heads :
It is the simplest form of the pressure vessels heads but it has less usefulness in pressure vessels heads.
So it is not preferred as much as of others because it has less pressure withstanding capacity than the other
types of heads due to lower radial section is available for pressure distribution. So maximum exposure is comes
on flat section so it is not economical.
Flat Heads
Commonly Used terms in the Flat Head is Flat Head Inside Diameter (ID), Knuckle Radius (R), Dish End Total Height (H) and Straight Face (SF). Flat Heads General Drawing Representation is shown in above Drawing.
Torispherical Heads or Flange and Dished Heads :
It is also most widely used heads. It also has more radial section for pressure distribution so it also withstand maximum pressure but lower than ellipsoidal Heads. So that it is less economical than ellipsoidal heads but it also widely use due to lower time required for forming than the ellipsoidal heads.
So that for same design condition, Torispherical Heads Thickness is nearly 1.77 times the Shell Thickness for same Design Pressure and Temperature.
Torispherical heads
Commonly Used Terms in Torispherical Heads is Inside Diameter (ID), Crown Radius (C.R), Knuckle Radius (K.R),
Dish End Total Height (H) and Straight Face (SF). Torispherical Head General Drawing Representation is shown in above Drawing.
It required less time of forming that ellipsoidal heads so it also more preferred heads due to simplicity of this heads.
This Heads is also Called as Flange and Dished Heads.
We can produce different types of flat-bottomed heads to meet the different needs of customers.
You can also give us your drawing, we can according your demand to manufacture it.
