Big Diameter ASME Carbon Steel Elliptical Dish Head for Pressure Vessel

Big Diameter ASME Carbon Steel Elliptical Dish Head for Pressure Vessel 

The Elliptical 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

Elliptical head:

Elliptical head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to storage liquids and gases. The hemispherical head is often made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. Hemispherical is the ideal shape for development of hemispherical dish end, because the pressure in the vessel is divided equally across the surface of the head. The radius (Ri) of the head equals the radius of the cylindrical part of the vessel. This type of hemispherical tank heads or hemispherical dish ends are made in most popular sizes and thicknesses.

The stainless tank head is one of the key pressure-bearing components and core structures of a planetary mixer.  It is not only an important part of the pot body but also a crucial element in ensuring the safe, efficient, and stable operation of the equipment under mixing, heating/cooling, and vacuum conditions. Its design, materials, and manufacturing process directly affect the overall performance, service life, and hygienic safety standards of the product.

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 provide custom edge preparation (beveling) for tank end caps?

A:Absolutely. We provide professional edge preparation and beveling services (such as V-type, X-type, or U-type bevels) based on your welding requirements. Custom holes, polishing, and surface treatments for tank end caps are also available.

Q: What manufacturing process is used, and what is the thinning tolerance after forming?
A: Our ellipsoidal heads are formed using advanced cold spinning or hot pressing processes. We guarantee strict tolerance control, ensuring the minimum thickness after forming meets your engineering design requirements without excessive thinning.

Q: What material grades are available, and do you provide MTC (Material Test Certificate)?
A: Yes, 100% of our products come with a 3.1 Material Test Certificate (MTC). We offer stainless steel (304/304L, 316/316L), carbon steel (A516 Gr.70, Q345R), and alloy steels suitable for high-pressure vessel and boiler manufacturing.

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.
