As an important pressure component of the container, the conical headis particularly important for its structural design and verification calculation.

When designing the structure of the conical head, first determine the size of the half apex angle of the required conical head, and then judge whether the cone head adopts the flange design according to the size of the half apex angle. If the half apex angle α ≤ 30°, the large end and the small end of the cone headcan use unfolded cone shells; if the half apex angle is 30° ≤ α ≤ 45°, the big end of the cone headshould be folded For the setting of the edges, the small end may not be folded if the strength calculation is satisfied; if the half apex angle is 45°≤α≤60°, both the big end and the small end of the cone shell should be set with hemming; if the half apex angle For α>60°, flat heads should be used instead, or calculations should be made by means of stress analysis.
