The hemispherical head has a simple radial geometry: the depth of the head is half the diameter. With a 47” ID, the required wall thickness is 0.2474”, about half the thickness of the shell. Because the head is thinner than the shell, a standard code 3:1 taper is used on the transition. (The transition is part of the stronger head, the shell is not tapered down on the straight section because it needs the full thickness.)
Hemispherical Head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to storage liquids and gasses. Our asme 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 main products of the company are: shell plate, elliptical head, dish head, flat head, spherical head, expansion joint, corrugated furnace and non-standard parts, and all kinds of stock heads are available for customers. The products are sold to more than 20 provinces and cities and regions in China and exported to foreign countries.

The end cap is the end cap on the pressure vessel and is a major pressure-receiving part of the pressure vessel. The role played is sealing. One is to make the top and bottom of the tank-shaped pressure vessel, the second is the pipe to the head, not ready to extend forward, then use a sealing head to seal the pipe in the form of welding. Products with similar functions to the head have blind plates and caps, but the two products are detachable. After the head is welded, it cannot be dismantled. The supporting fittings include pressure vessels, pipes, flanges, elbows, tees, and four-way products.
The head is an indispensable part of pressure vessel equipment in many industries such as petrochemicals, atomic energy and food and pharmaceuticals.
