Selection tips for heads in heated reactors
Sep 18, 2018

The heating reactor has many applications in life. The head is one of the components that constitute it. It is mainly installed at the two ends of the heating kettle. Its types are various, and the more common ones include hemispheres, ovals, butterflies, etc. . Different heads have different characteristics, so there is also a difference in the applicable Chengdu for the heated reactor.


For example, a hemispherical head has the same advantages as a spherical container, that is, its surface area is small under the same volume, and the required wall thickness is lighter and lighter under the same diameter and pressure, which is very labor-saving. However, the depth is large and the manufacturing is difficult. The medium, low pressure and small volume heating reactors are not suitable.


The elliptical head consists of a half ellipsoid and a cylindrical shell with a certain height to avoid the need to provide a weld at the joint of the ellipsoid edge and the cylindrical shell to transfer the weld to the cylinder area. In order to avoid the occurrence of edge stress superposition. The elliptical head is relatively simple to manufacture, and the force condition is better than that of the butterfly head. In particular, the large volume heating reactor often uses an oval head.


The depth of the butterfly head can be adjusted by the transition radius, but because the curvature of the butterfly head busbar is not continuous, there is local stress, so the force is not as good as the elliptical head. It can be seen that before selecting a head for a heated reactor, a basic understanding of the head is required to find a suitable part.
