What is a header

Head refers to the element used to close the end of the container to isolate its internal and external medium, also known as end cap. According to the shape of surface of head, it can be divided into convex, conical, flat plate and combined shape. Convex head refers to the head whose outer surface shape is convex, such as hemispherical, oval, disk-shaped and unfolded spherical head. In welding, it is divided into butt-welding head and socket-welding head. They are used for various container equipments, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipments. 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 alloys.

Precautions for the use of headers

Please measure the outer circumference of the head.
