The dish head is a main pressure bearing of the pressure vessel. Is welded to connect the cylinder, play a sealing effect. According to the different geometric shapes, can be divided into spherical, oval, dish, ball crown, cone and flat and several, including spherical, oval, dish, ball crown head is also known as convex head The Head to withstand the load capacity is better than the blind and cap, widely used in petrochemical, power, aerospace, nuclear power to food and pharmaceutical industry, many pressure vessel equipment. Such as tanks, heat exchangers, towers, reactors, boilers and separation equipment.
