Classification of the head
Ellipsoid head, hemispherical head and hyperboloid head are three types of ASME pressure vessel disc head.
Ellipsoidal head
This is also known as a 2:1 oval head. This head shape is more economical because the height of the head is only a quarter of its diameter. Its radius varies between the major axis and the minor axis.
Hemispherical head
A sphere is the ideal shape for the head because the pressure in the container is evenly distributed over the surface of the head. The head radius (R) is equal to the radius of the cylindrical part of the container.
Spherical head of complex surface
These have a disc head with a fixed radius (CR), the size of which depends on the type of spherical head. The transition between the cylinder and the plate is called the knuckle. The steering knuckle is circular.

Product name:Titanium Hemispherical Dish Head
Standard: ASME VIII-I, DIN28013
Material: Titanium GR1, GR2
Size: Customized
Titanium Hemispherical Dish Head
Material: titanium, titanium alloy
Outer diameter: dn15-dn1200
Wall thickness: sch5-sch160.
Standard: ASME DIN JIS BS
Scope of application: petrochemical industry, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproof treatment, pipeline, etc
Purpose: pipe fittings welded on the pipe end or installed on the external thread of the pipe end to cover and block the pipe. It is used to close the pipeline and has the same function as the pipe plug. The pipe cap includes the design of convex pipe cap, conical shell, reducing section, flat cover and tightening mouth.
The most common types of spherical head:
Pan head
This is a spherical head. The radius of the plate is equal to the diameter of the cylinder to which it is attached. The radius of the knuckle is equal to one tenth of the diameter of the cylinder.
Ellipsoidal head
This is a semicircular head, also known as a semicircular ellipsoid head. The radius of the disk is 90.45% of the diameter of the cylinder (ICR=0.9045 x od). The radius of the steering knuckle is (IKR=0.1729 x od).
