Dished ends (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. Our high quality and innovative vessel head includes elliptical head, torispherical head, hemispherical head and conical head, etc. STRENGTH Equipments had been supplying ASME certificated dished heads at a competitive factory price.

Pickling and Passivation
The dished ends is generally overall forming and butt welding after split forming.
The overall forming is mainly formed by hot(stamping) forming and cold(spinning) forming. The butt welding after split forming is generally to split forming and then butt welding.
Overall Forming Cold forming, also known as cold spinning, the use of a spinning machine at normal temperature for pressing. It is suitable for the head with large diameter and small thickness.
Hot forming, also known as hot stamping, the steel plate is heated to the specified temperature, the use of press and mold to cooperate with the pressing molding. It is suitable for thick head.
