Construction of spherical tanks

The spherical tank consists of a spherical tank body, a support (or pillar), and accessories. The spherical tank body is a spherical container made of welded spherical shell plates, which is the pressure bearing part of the spherical tank. The support of spherical tanks is often a column type support made of multiple steel pipes, with the equatorial tangent column type being the most common.

Accessories for spherical tanks: There are external ladders, valves, and instruments, and some large spherical tanks also have internal turnstiles.
