Product Description

1.Production Introduction
Torispherical dish end, (also called tank heads, vessel head), is the end caps on a cylindrical shaped pressure vessel which is made with carbon steel, stainless steel and other alloy steel. The Pressure vessel head is cold processed or hot-formed, seamless and stress treated, these tank heads are widely used in industrial storage or pressure vessels such as storage tanks, heat exchangers, towers, reactors, boilers and separations equipment.
The torispherical dish end 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.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.

2. Main Features
