company news about How do hemispherical heads distribute pressure uniformly?

Hemispherical heads distribute pressure uniformly because their curved shape aligns with the direction of pressure forces, ensuring equal stress is exerted across the entire surface rather than concentrating at specific points.

Pressure acts perpendicular to a surface. In a hemisphere, every point on the inner surface curves such that the pressure force is directed along the head’s radius—toward the center of the hemisphere’s curvature.

This radial force is evenly supported by the head’s material and the vessel’s cylindrical body it attaches to, eliminating the high stress concentrations that occur in flat heads (where pressure pushes against a flat surface, creating intense stress at the edges) or less curved shapes.
