Custom Made Elliptical Torispherical Dished Heads for Sand Filter Storage Tanks

Custom Made Elliptical Torispherical Dished Heads for Sand Filter Storage Tanks

The Torispherical head is the most common type of heads. It can be seen in various equipment such as pressure vessels, storage tanks, heat exchangers, Planatery Mixer Machine etc. It has relatively high pressure tolerance and low molding difficulty.

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

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.
