Tank ends: Tanfield Metal Spinners’ Expertise (Dished ends, Flat Flanged ends & Hemispheres)

At Tanfield Metal Spinners, we are masters in the art of metal spinning, and our specialty lies in crafting precision tank ends. With a wealth of experience in this craft, we take pride in our ability to manufacture tank ends that meet the highest standards. Our expertise extends to manufacturing tank ends ranging from 200mm to 2000mm in diameter, using a wide spectrum of materials, from 1mm mild steel to 10mm stainless steel.

Types of Tank ends 

Tank heads or pressure vessel heads, often referred to as Dished and Flanged ends, come in various shapes and sizes, each meticulously designed for specific applications. The primary types include: 

1. Torispherical 6% and 10% Dished End: These possess a shallow, dished shape with a knuckle radius. Widely used in pressure vessels and storage tanks, they are known for their structural integrity. 
2. Elliptical Dished End: Featuring a pronounced elliptical shape, these ends are versatile and find applications in various industries, from cookware to industrial containers.
3. 2:1 Semi-Elliptical Dished End: These heads are segments of an ellipse and are commonly used in pressure vessels and storage tanks, offering efficient stress distribution properties. 
4. Table 7 Storage type ens. Shallow tank style ends for storage or generally in accordance with BS2594  
5. Joggled Ends to European standards EN286-1 1991. 
6. Flat flanged End: Known for their flat dished shape with no knuckle radius, they are suitable for applications where a smooth interior finish is essential. 
7. Hemispherical End: Spherical in shape, these are typically employed in high-pressure vessels, such as boilers and nuclear reactors, where strength and pressure containment are paramount. 
8. Toriconical Dished End: These are a combination of a toroidal and a conical shape, often used in the fabrication of storage tanks and pressure vessels, providing both strength and efficient use of space. Also referred to as a cone.  
9. Dished Plate: A dished plate is a flat plate with a curved or dished shape. It is commonly used in the construction of tanks, silos, and various containers. 

The Functions of Dished Ends 

Dished ends serve several crucial functions across diverse industries: 

1. Pressure Containment: These ends are integral components of pressure vessels, ensuring the safe containment of gases and liquids under high pressures. 
2. Uniform Stress Distribution: Their unique curvature helps distribute stress uniformly across the surface, reducing the risk of material failure. 
3. Improved Aesthetics: Beyond functionality, dished ends can add an aesthetically pleasing finish to products, making them ideal for architectural and decorative applications.
