Elliptical head

Elliptical head is a type of pressure vessel head consisting of a curved surface with a shape that resembles an ellipse or a squashed circle.

The elliptical head ( or named ellipsoidal head ) which is a head consisting of two parts: a rotating ellipsoidal sphere and a cylindrical straight section. Elliptical tank head is fabricated to have a certain shape instead of a particular dish radius or knuckle radius. The dish radius is approximately 90% of the diameter and the knuckle radius is approximately 17% of the diameter. 2:1 elliptical flanged and dished heads are ASME compliant.

Material

• Carbon steel tank ends/caps, flat dished head: SA516 GR60N,GR70N
• Stainless steel ellipsoidal dished end, elliptical tank head: SA240 304, 316
• Titanium alloy pressure vessel ends: SB256 GR1, GR2, GR5

Usage of elliptical head

Elliptical heads are commonly used in the design and construction of tanks and pressure vessels that operate under high pressure conditions. They are typically used at the end of cylindrical vessels where the transition is made from the cylindrical part to the end closure.

Some common applications of elliptical heads include:

• Pressure vessels: Elliptical heads are frequently used as end closures for pressure vessels such as boilers, reactors, and distillation columns. These vessels are used in industries such as oil and gas, chemical processing, and power generation.
• Tanks: Elliptical heads can be used in the construction of storage tanks for liquids or gases such as water, fuel, and natural gas. They provide a smooth transition between the tank body and the tank head.
• Heat exchangers: Elliptical heads can also be used in the construction of heat exchangers such as shell-and-tube heat exchangers, which are used in a wide range of industries including food processing, pharmaceuticals, and HVAC.

Elliptical heads are widely used in various industries where pressure vessels, tanks, or heat exchangers are required to operate at high pressures and temperatures. The specific application, size, material, and thickness of an elliptical head depend on the requirements and design standards of the project.

Features

End Caps are used for connecting pipes of different diameters and find wide applications in various chemicals, construction industries, paper, cement & ship builders.

Pipe caps are widely well-known for the utmost output and outstanding results that it gives.

It is commonly made from the one steel plate, so it should be seamless. The pipe end caps are available in various shapes, like the hemispherical, oval, round etc.
