A torispherical head is not just a rounded pressure vessel cap—it must meet strict ASME code standards for geometry and thickness. In this blog, we explain how ASME-compliant torispherical heads are designed to prevent costly mistakes and ensure safety. We cover the key specifications required, the importance of using the correct radii, and the formula for calculating minimum thickness. Learn why these heads balance safety, cost, and code compliance, and why "close enough" isn't good enough.
