The torispherical headprocessed in China are generally 10% of the standard torispherical head, and its curved surface is much smoother than that of the 2: 1 elliptical head.

It has the following advantages when used:

It is easier to process than elliptical head, with small processing volume, good forming quality and cheaper.

The blank material used is less than the elliptical head, which saves more raw material.

The disadvantage is that the force is not as good as the elliptical head. The same diameter, pressure, and material are about 1.54 times thicker than the elliptical head.

If the internal pressure of the device is relatively small, it is very economical to choose torispherical head.
