Carbon steel ellipsoidal head for oil tank

We can produce up to 8,000 mm diameter asme torispherical dish end depending upon thickness of material and wall thickness up to 30 mm depending upon material and diameter. custom forms and dimensions are also available.

Torispherical Head (also called torispherical dish end or torispherical ends) is widely applied for pressure tanks to storage liquids and gasses. The torispherical head consists of a spherical surface, a cylindrical edge of a certain height, and a transition section connecting the above two parts with a radius of curvature smaller than the radius of the sphere. 

Our asme torispherical head can be made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. The stress distribution of torispherical dish head is not as uniform as elliptical head, but the manufacturing processing of the torispherical head is easier. However, torispherical dish end is the better option when the elliptical head of the mold processing is difficult. We can fabricate torispherical ends in most popular sizes and thicknesses.

Compared with elliptical head,  due to its easier manufacturing processes, the torispherical head is often used in addition to the pressure is larger diameter pressure vessel.
