Shallow head is used to close the end of the container so that its internal and external media isolation, also known as the end cover. The head of a cylindrical container is usually a rotating shell. According to the shape of the head surface can be divided into convex shape, cone shape, flat shape and combination shape. Convex head refers to the head whose outer surface is convex, such as hemispherical, elliptic, saucer and unflanged spherical head. Some gas cylinders adopt convex to inward-shaped bottom head, which can not only ensure the strength, but also meet the requirements of safe use.

The shallow head is a part of the vessel and is welded to the cylinder. According to the different geometric shapes, it can be divided into spherical, elliptic, saucer-shaped, spherical crown, conical shell and cover, among which spherical, elliptic, saucer-shaped and spherical crown head are collectively referred to as convex head. Welding is divided into butt welding head, socket welding head. Used for all kinds of containers and equipment, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment. The materials are 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 alloy, etc.
