The head is an indispensable part in the pressure vessel equipment of petrochemical, atomic energy and food and pharmaceutical industries. According to different geometric shapes, it can be divided into spherical, elliptical, dish, spherical crown, cone shell and flat cover, among which spherical, elliptical, dish, and spherical crowns are collectively referred to as Convex head. In the welding, it is divided into a butt welding head and a socket welding head. Used in a variety of container equipment, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment. Materials include carbon steel (A3, 20#, Q235, Q345B, 16Mn, etc.), stainless steel (304, 321, 304L, 316, 316L, etc.), alloy steel (15Mo3 15CrMoV 35CrMoV 45CrMo), aluminum, titanium, copper, nickel and nickel Alloys, etc.
