ASME SA516 Gr.70 Carbon Steel Elliptical Head End Cap / Dish End for Pressure Vessel
A dish end / dish head is a type of end cap used to seal the ends of pressure vessels and tanks, and they play a crucial role in maintaining the structural integrity of these containers. Dish ends are commonly made from materials such as carbon steel, stainless steel, aluminum, cladding materials. They are typically attached to the vessel or tank using welding, bolts, or clamps. Dish ends are designed to withstand high pressures and temperatures, and they are commonly used in industries such as oil and gas, chemical processing, and food and beverage production.

There are several types of dish ends or dish heads used in specific requirements of the vessel or tank.
The most common types include:
1. Hemispherical
This type of dish end has a shape resembling a half-sphere and is the most commonly used type.
2. Torispherical
This type of dish end has a shape resembling a portion of a sphere with a flattened zone at the base.
3. Ellipsoidal
This type of dish end has a shape resembling a flattened sphere and is often used when head height is limited.
4. Conical
This type of dish end has a shape resembling a cone and is used when the vessel requires a bottom with slope for easy discharge of contents.
5. Flat
This type of dish end has a flat shape and is typically used in low-pressure vessels or tanks.

How to Choose a suitable dish head for a pressure vessel?
It depends on several factors, including the vessel's size, shape and intended application.
Vessel size and shape: The dish head should be chosen to match the size and shape of the vessel. This will ensure a proper fit and prevent leaks.
Pressure and temperature requirements: The dish head should be able to withstand the pressure and temperature requirements of the vessel. This may require selecting a material with high strength and/or corrosion resistance.
Material compatibility: The dish head material should be compatible with the contents of the vessel to prevent contamination or chemical reactions.
Regulatory requirements: The dish head should meet any relevant regulatory requirements, such as those set by ASME or other industry standards.
Cost: The cost of the dish head should also be considered, as it may vary depending on the material and manufacturing process used.
