Titanium Hemispherical heads
Titanium Spherical Heads ,aso called Titanium dish head,Titanium Elliptical Heads.It is a kind of boiler part in pressure vessel. It is usually used at both ends of pressure vessels. Then there is a welding pipe fitting product used for plugging at the end of the pipe. There are many forms. The head is a part of the container and is welded to the barrel. According to the different geometric shapes, it can be divided into spherical, elliptical, disc, spherical crown, cone shell and cover, among which spherical, elliptical, disc and spherical crown head are collectively referred to as convex head. In the welding is divided into butt welding head, socket welding head. Used in various vessels and equipment, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment, etc.

Diameter: 250mm-3000mm
Thickness: 2mm-20mm
Height: 30mm --- 50mm
Standard: ASME VIII-I, DIN28013
Material: GR1, GR2, GR7, GR12
Generally, molding and spinning are used for processing. The bottom flatness of molded flat bottom head is high, the blanking size is large and the cost is high, which is suitable for equipment with high requirements; With the spinning process, the flat bottom of the produced flat bottom head is slightly worse, the blanking size is smaller, and the cost is lower, but it does not affect the use of general equipment. The characteristics of spinning head are: a large workpiece can be formed with a small deformation force; The use of equipment is relatively simple, small and medium-sized sheet metal parts can be spun by ordinary lathe; The mold is simple, only one core mold is needed, and the material requirements are low.

Product name:Titanium Pressure Vessel Hemispherical Tank Head
Standard: ASME VIII-I, DIN28013
Material: GR1, GR2, GR7, GR12 etc.
Size: Customized
The Hemispherical Tank Head head refers to the element used to close the end of the container to isolate the internal and external media, also known as the end cover. The head of cylinder descriptors is generally a rotating shell. According to the shape of the head surface, it can be divided into convex shape, conical shape, flat shape and combined shape. Convex head refers to the head whose outer surface is convex, such as semi spherical, elliptical, dished and non folded spherical head. Some gas cylinders adopt the combined bottom head with convex face inward, which can not only ensure the strength, but also meet the needs of use.
Matterial: titanium GR1, GR2, GR7, GR12 etc.
Type: select suitable head types according to the requirements and effectiveness of industrial equipment, such as elliptic, butterfly, cone, ball, etc
Size: generally, the height width ratio of the head is manufactured according to international standards, or can be customized according to customer requirements
Scope of application: the head is widely used in petroleum, electronics, chemical industry, medicine, textile, food, machinery, construction, nuclear power, aerospace, industry and other industries.
