Two Heads of Batch Reactor
Two Main Types of Head of Batch Reactors:
Torispherical:
Torispherical heads are the most common type of head used for manufacturing pressure vessels and they are cost effective.
In torispherical head I.C.R is generally equal to the I.D of the head or may be less. Recommended
range of I.C.R is between 90% to 95% of the I.D of the head.
The recommended value of I.K.R shall be in the range of 6% and 10% of the I.C.R of the head.
The S.F is generally between 10mm and 30mm. Depends upon on the diameter and thickness of the head to be formed.
2:1 Semi-Ellipsoidal:
2:1 Semi-Ellipsoidal heads are generally deeper than a torispherical head and therefore are more stronger
and able to resist high pressures than torispherical heads. These heads are formed with more difficulty due to
the greater depth required. This result in high prices as compared to torispherical head, but this leads to
reduction in material thickness as the strength is greater.
The recommended I.C.R shall be 0.8 of the O.D of the head.
The recommended I.K.R shall be 0.154 of the O.D of the head.
The maximum diameter that can be form a 2:1 Semi-Ellipsoidal head shall be app. 2300mm of the I.D.
The S.F is between 10mm and 30mm.
