High quality Q235B carbon steel hemisphere 900mm with 4mm thickness for outdoor fire pits
Steel hemisphere allow more pressure than any other head. However, the hemispherical head is the most expensive to form, as they consists of a number of petals or gores. The number of which depends on the size of the head and the thickness of the plate to be used. The depth of the head is half of the diameter.
Hemispherical Head (also called hemispherical tank heads or hemispherical dish ends) is widely applied to make pressure tanks to storage liquids and gasses. Our asme hemispherical head is often made with carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. Hemispherical is the ideal shape for development of hemispherical dish end, because the pressure in the vessel is divided equally across the surface of the head. The radius (Ri) of the head equals the radius of the cylindrical part of the vessel. This type of hemispherical tank heads or hemispherical dish ends are made in most popular sizes and thicknesses.
