Hemispherical Tank Heads

Hemispherical Tank Heads: The Ideal Choice for High-Pressure Applications

The Trusted Source for Hemispherical Tank Heads Across Industries

When it comes to tank head manufacturing, Haipei Industry stands out as a trusted supplier of seamless ASME hemispherical tank heads. With a wide range of sizes from 6-5/8" OD to 60" ID, our hemispherical heads are engineered for superior pressure resistance. Compared to 2:1 Elliptical Heads, hemispherical designs require less minimum thickness to hold high pressure, making them the optimal choice for pressure vessel applications.

Why Choose Hemispherical Tank Heads?

Hemispherical tank heads, also known as hemispherical dished ends, are a preferred option for pressure vessels due to their optimal shape. Their uniform structure distributes internal pressure evenly across the surface, ensuring enhanced durability and safety. They are commonly used in both liquid and gas storage tanks for a variety of industries.

Our Manufacturing Capabilities

At Haipei Industry, we specialize in producing multi-piece hemispherical heads from stainless steel and other nickel alloys, tailored to various sizes and thicknesses to meet industry demands.

Specifications of Our Hemispherical Heads:

• Diameter Range: 20" – 72"

• Material Thickness: 10 gauge – 3/8" Plate

• Dish Radius: 50% of the diameter

General Notes:

• Manufactured from high-quality stainless steel and exotic alloys

• Available with polished finishes (Inside/Outside) from 80 Grit to 320 Grit (5-10 Ra)

• Custom-built as Inside Diameter (ID) or Outside Diameter (OD)

• Customers are responsible for their own design; once finalized, our team is ready to begin production

Compliant with ASME Standards

Haipei Industry ensures all hemispherical tank heads meet stringent American Society of Mechanical Engineers (ASME) standards. This means our products comply with the highest industry requirements, including material selection, fabrication, inspection, testing, and certification. Our dedication to ASME compliance guarantees superior quality and reliability.

Applications of Hemispherical Tank Heads

Hemispherical heads excel in high-pressure environments and large-diameter pressure vessels. Their simple radial geometry—where the depth is half the diameter—allows for excellent force distribution across the surface, enhancing structural integrity. Industries that require safe and effective pressure containment prefer hemispherical heads over other designs.
