Seal Head is used to close the end of the container so that its internal and external media isolation components, also known as the end cover.It is a part of a container and is connected to the cylinder by welding.
According to the different geometric shapes, it can be divided into hemispherical, elliptical,dished,spherical crown,cone shell and cover, among which hemispherical head,elliptical head,dished head,spherical crown head is also known as convex head.In welding, it can be divided into butt welding head and socket welding head,used for various vessels and equipment, such as storage tanks, heat exchangers, reactors, boilers and separation equipment, etc. The materials are carbon steel (A3 20# Q235 Q345B 16Mn, etc.), stainless steel (304 321 304L, 316 316L, etc.), alloy steel,etc.
Application:
The head is an indispensable part of pressure vessel equipment in petrochemical, atomic energy, food and pharmaceutical industries.
●The head is the end cover on the pressure vessel, which is a main pressure bearing component of the pressure vessel.The function is the sealing function.One is to make the bottom and bottom of the can-shaped pressure vessel, and the other is that the pipe has reached its end and is not going to extend any further, so a head is used to seal the pipe in the form of welding.Similar to the function of the head are the blind plate and the pipe cap, but these two products can be removed.The head can not be disassembled after welding.The supporting pipe fittings are pressure vessels, pipes, flanges, elbows, three, four and other products.
●The quality of the seal head is directly related to the long-term safe and reliable operation of the pressure vessel.
●The seal head can also be used to make fire pit garden decorations.
