[0002] Conical heads are important components of pressure vessels. Their outer shell surface is conical, and they are mainly used to seal the end of the vessel and withstand internal pressure. Conical heads are widely used in pressure vessels, storage tanks, pipeline systems, etc., and are especially suitable for scenarios that require medium diversion, change of flow rate, or connection of pipelines with different diameters, such as reactors, separators and pipeline ends in the chemical, petroleum and pharmaceutical industries.

[0003] When workers need to seal containers, they weld conical heads onto the containers to seal them. However, existing conical heads may become unstable due to insufficient rigidity caused by the difference between internal and external pressures during use, resulting in inward depressions on the surface of the conical head.
