ASME SA516 Gr.70 Carbon Steel Elliptical Head, Dished Head, Shell Cover For Pressure Vessel
Elliptical head, also called ellipsoidal head, is a kind of head with elliptical shape. The ellipsoidal head is a head consisting of two parts: a rotating ellipsoidal sphere and a cylindrical straight section. Elliptical heads have widespread use in various industries, including petrochemical, oil and gas, and power generation. They are also suitable for pressure vessels such as boilers, storage tanks, and heat exchangers. ASTM A516 Gr70 Carbon Steel Elliptical head has high strength and good toughness, wear resistance, excellent fatigue resistance, good impact resistance, welding ease of processing and cold forming properties.
A dished head is a component of a vessel which is welded to a cylinder. According to different geometrical shapes, they can be divided into several kinds, such as spherical, ellipsoidal, disc, spherical crown, conical shell and flat cover, among which spherical, ellipsoidal, disc. In terms of welding, it is divided into butt weld vessel head and socket weld vessel head. They are used for various kinds of vessels and equipments, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment. Elliptical heads (also known as ellipsoidal heads or elliptical dish ends) are typically made of carbon steel, stainless steel, alloy steel, copper, nickel alloy, etc.
