There are many uses of dished head in our daily life, Jetvision shares something with you

Dished head is an indispensable and important part of pressure vessel equipment in many industries from petrochemical, atomic energy to food and pharmaceutical.

Dished head end is the end cap of pressure vessel, which is a main pressure bearing part of pressure vessel. The role played is a sealing role. One is made into the top and bottom of the tank-shaped pressure vessel, and the other is that the pipe reaches the dished head and is not going to be extended forward, then a dished head is used to seal the pipe in the form of welding.

Similar to the role of vessel dished head, there are blind plate and pipe cap, but those two products can be disassembled. But the dished head cannot be disassembled after it is welded. The quality of the vessel dish head is directly related to the reliable operation of the pressure vessel. The pipe fittings with which it is used are pressure vessels, pipes, flanges, elbows, tees, crosses and other products.

Vessel dished end is also more common in daily life and is a common kind of pressure vessel equipment.

Application scope of dished head: petroleum, electronics, heating, chemical, pharmaceutical, sewage treatment, light textile, food, machinery, construction, nuclear power, aerospace, pressure vessel, military and other industries.
