Heads/End Closures are critical pressure-retaining components that seal the ends of steam generator vessels, ensuring structural integrity and safety under high-pressure steam conditions.
Heads/End Closures are hemispherical, elliptical, or dished components that form the sealed ends of cylindrical steam generator vessels in industrial applications. They are engineered to withstand internal pressures up to 2500 psi (17.2 MPa) and temperatures exceeding 600°F (315°C), distributing stress uniformly to prevent deformation or failure. These closures incorporate flanged connections for piping, inspection ports, and safety devices, and are designed with specific geometries (e.g., 2:1 elliptical heads) to optimize pressure resistance and minimize material usage while complying with ASME Boiler and Pressure Vessel Code standards.

Common types include hemispherical heads (for high pressure), elliptical heads (2:1 ratio for balanced strength), and torispherical heads (with knuckle radius for cost-effectiveness), selected based on pressure, temperature, and fabrication requirements.
They are designed with pressure-relief features, non-destructive testing (e.g., ultrasonic inspection), and compliance with standards like ASME BPVC to prevent catastrophic failures, with regular maintenance checks for corrosion or fatigue cracks.
