In terms of actually usage, torispherical head can’t be a kind of head with great bearing. This type of head is only made for sealing. There are two main reasons for its existence. The first aspect is that the sealing of the head is very excellent on a specific container. The second point is that this type of head can also work to the maximum extent of our container stability.

When talking about pressure vessels, although a lot of the heads are applied to the pressure vessels, the torispherical heads are not. Torispherical heads are used on general sealed containers. The requirements of the physical environment for such containers must first be sealed, followed by stability.

Regarding to the sealing performance, the torispherical head can be completely achievable. Careful configuration of the head during the installation process is OK. The torispherical head itself has a certain thickness, so high sealing can be achieved. So how is stability achieved? In fact, the stability of this kind of head is mainly realized by the physical structure. The so-called torispherical head is actually a dish-like head on the surface. This kind of head may not be highly resistant to internal pressure, but it can be well decomposed for external forces. The decomposition is reflected in the stability of our use of this head. As for the influence of the pressure range of the torispherical head on the use, we generally do not consider it. It is necessary to consider the using of the head when it is used under what circumstances.
