For everyone, you should have a understanding of the head. Nowadays, the types of heads that appear on the market are diverse. The head can be found in many places. Its scope of application is also very broad. Depending on the geographical environment, the types of heads we see in different locations are different. There are many types of flat heads, spherical heads, etc.

This article mainly explains why the flat head should not be used for sealing internal pressure vessels:

One of the main reasons is that the flat head is relatively poor bearing capacity.That is to say, under the same pressure, in flat head, spherical head, conical head, all types of heads, the bearing force of flat head is the worst.

On the other hand, from the perspective of the pressure vessel, the head of pressure vessel generally chooses spherical head.

The bearing force of the spherical head is much stronger than the flat head, the same reason, under the same pressure, in flat head, spherical head, tapered head all types of head, spherical head of the force is much stronger than the flat head.

In this case, the spherical head will save more raw materials than the flat head. As the amount of raw materials is reduced, the economic cost will be much better than using flat head.
