Torispherical Dish End

A torispherical dish end is a curved pressure vessel head commonly used to close the top or bottom of cylindrical tanks, pressure vessels, boilers, and other industrial equipment. Its torispherical profile combines a shallow dished shape with a rounded knuckle, providing a practical balance between pressure resistance, manufacturing cost, and overall vessel dimensions.

Our torispherical dish ends are manufactured from carbon steel, stainless steel, and alloy steel, with customized dimensions, thicknesses, materials, and surface finishes available according to customer drawings or technical requirements.

We manufacture dish ends for a wide range of industrial applications, including pressure vessels, storage tanks, heat exchangers, chemical equipment, water treatment systems, food processing equipment, and pharmaceutical tanks.

Specification

Torispherical heads — also referred to as torispherical dish ends or simply torispherical ends — are commonly used in pressure vessels designed for the storage of liquids and gases. Geometrically, this type of head comprises three distinct sections: a spherical central portion, a straight cylindrical flange of specified height, and a transitional knuckle region that connects the spherical and cylindrical parts. The knuckle features a radius of curvature that is intentionally smaller than that of the spherical section.

These heads can be manufactured from a variety of materials, including carbon steel, stainless steel, and both austenitic and non-ferritic metals that are suitable for cold forming. In terms of mechanical performance, the stress distribution in a torispherical head is less uniform than that of an elliptical head; however, this design offers significant advantages in terms of manufacturability. The forming process is comparatively simpler and more cost-effective, making it a preferred choice when elliptical heads are difficult to produce due to mold constraints.

We offer torispherical ends in a wide range of standard sizes and thicknesses, and can accommodate custom requirements to meet diverse application needs.

FAQ:

Q: What information should I provide when making an inquiry?

A: If you have production drawings, we will strictly follow them. If not, you can provide the product details, such as: Material ,Type of head (e.g., elliptical, hemispherical, dished, flat, etc.)Special tolerances or requirements

If needed, we can create drawings based on your specifications, and you can confirm the final product design before production.

Q: Can you help us source related products?

A: Yes, our company works with several nearby ancillary businesses, including suppliers of flanges, boilers, and oil refining equipment. We can help you source the highest quality products at competitive prices.

Q: What types of dish heads do you offer for sand filter tanks?

We manufacture a full range of dished ends, including 2:1 elliptical heads, torispherical (flanged & dished) heads, hemispherical heads, and flat heads. For sand filter vessels, the 2:1 elliptical type is the most commonly recommended due to its balanced stress distribution and cost-effectiveness under medium-to-high pressure conditions.

Q: What materials are available for your dish heads?

We offer dish heads in carbon steel (e.g., Q235B, Q345R, A516 Gr.70) and stainless steel (e.g., 304, 304L, 316L). For sand filter applications exposed to corrosive water or outdoor environments, we recommend stainless steel 316L or carbon steel with an epoxy/powder coating for enhanced rust protection.

Q: How do I choose the right thickness for my dish head?

The required thickness depends on your design pressure, operating temperature, and diameter. We follow ASME Section VIII or GB/T25198 standards to calculate the minimum required thickness. If you provide your vessel's design parameters, our engineering team can recommend the optimal thickness at no extra charge.

Q: What quality inspections do you perform?

Each dish head undergoes a rigorous quality control process, including:

Dimensional inspection (diameter, straight flange height, surface profile)
NDT (Non-Destructive Testing): UT (Ultrasonic Testing) and RT (Radiographic Testing) as required
Hydrostatic pressure testing to verify pressure integrity
Surface finish inspection for corrosion resistance

All test reports are provided with each shipment.

Q: How quickly can you deliver?

For standard sizes in stock, delivery can be completed within 7–15 days. For custom orders, the lead time is usually 20–35 days after drawing approval, depending on the quantity and material availability. We also offer expedited production for urgent projects—please contact us directly to discuss your timeline.
