Product description

The head is a part of the container that is welded to the cylinder. Can be divided into spherical, oval, dish, ball crown, cone shell and cover, etc.

Brief introduction of the head:

The head refers to the element used to close the end of the container to isolate the inside and outside media, also known as the end cap. The head of a cylindrical container is generally a rotary shell. According to the shape of the head surface, it can be divided into convex shape, cone shape, flat shape and combined shape. Convex head refers to the head with a convex outer surface shape, such as hemispherical, oval, dish-shaped and non-flanged spherical head. Some cylinders adopt convex inward combined bottom head, which can not only ensure strength, but also meet the needs of safe use.

Definition of head:

The head is a part of the container that is welded to the cylinder. According to the different geometric shapes, it can be divided into spherical, oval, dish, ball crown, cone shell and cap, etc., among which the spherical, oval, dish, ball crown type head is also collectively known as convex head. In welding, it is divided into butt welding head and socket welding head. Used in various container equipment, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment. Material is 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.

Purpose of the head:

The quality of the head is directly related to the long-term safe and reliable operation of the pressure vessel.

The head is an indispensable part of pressure vessel equipment in petrochemical, atomic energy, food and pharmaceutical industries.

The head is the end cap on the pressure vessel, which is a main pressure component of the pressure vessel. It acts as a seal. One is to form the bottom of the tank pressure vessel, the other is the pipe to the end, no longer ready to extend forward, then use a head in the pipe to seal in the form of welding. Similar products to the head are the blind plate and the tube cap, but those are removable. After the head is welded, it can not be removed. With its supporting pipe fittings are pressure vessels, pipes, flanges, elbows, tee, four and other products.
