Spherical storage tank
>>>
Spherical storage tank refers to a storage tank with a spherical shell. It mainly consists of a spherical shell, a support, and auxiliary components. There are three types of spherical shell structures: single layer, double layer, and multi-layer. The spherical shell is formed by welding multiple pre pressed spherical plates into a certain shape. The main types of spherical tank plates are annular (melon petal) type and football type. Supports include pillar type, semi buried type, skirt type, etc. Auxiliary components include operating platforms, external ladders, manholes, and valves. The spherical tank used to store liquefied gas is also equipped with cooling spray, spray and fire insulation spray devices outside. For spherical tanks under pressure or vacuum, safety valves or vacuum valves are installed.
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.
The tower is divided into plate tower and packed tower according to structure

Process equipment of tower-cylinder welded structure
Tower refers to the equipment used to carry out physical processes such as separation or absorption, and change the composition of gas or liquid complex mixture. Also known as "tower equipment". The ratio of height and diameter is large, and there are certain accessories inside and outside the tower.
Installation, use and maintenance of half volume heat exchanger
>>>
In order to prolong the service life of the heat exchanger, reduce the maintenance workload, save energy, and maintain efficient heat exchange, when the total hardness of the heated water is greater than or equal to 300mg/L (CaCO3), appropriate anti scaling measures should be taken to soften or stabilize the water quality, and the scale on the outer wall of the U-tube should be cleaned regularly.
Difference between positive displacement heat exchanger and semi positive displacement heat exchanger
>>>
The difference between the volumetric heat exchanger and the semi volumetric heat exchanger is that the semi volumetric heat exchanger tube bundle has a cylinder, while the volumetric heat exchanger does not.
