Characteristic Comparison Between Head Types
1. Hemispherical head Advantages: Minimum surface area, small thickness required, and large pressure-bearing capacity. Disadvantages: The depth is large and the punching is difficult. 2. Elliptical head Features: Small surface area and the standard head and the cylinder are at the same thickness with large pressure-bearing capacity, and it is easy to be stamped and formed. 3. Dish-shaped head Advantages: It is convenient for manual processing or stamping Disadvantages: It has larger edge stress. 4. Spherical crown head Advantages: Simple structure and convenient manufacturing. Disadvantages: There is a lateral thrust and a large edge stress. 5. Conical head Advantages: It is convenient to introduce and extract the viscous liquid or solid materials in the equipment. Also it can be used as a two-part variable diameter section on equipment with unequal diameters. Disadvantages: There is a large lateral thrust and edge stress. 6. Flat head Advantages: Easiest to manufacture...
