The typical chemical equipment commonly used are reaction tanks, towers, heat exchangers, storage tanks and so on.
Chemical equipment is in accordance with the chemical equipment manufacturing process drawings, commonly used drawings of chemical equipment diagrams, assembly drawings, parts diagrams, parts diagrams, pipe orientation diagrams, table diagrams, and pre-weldings diagrams, as the construction design documents and engineering drawings, general drawings, standard drawings, chemical equipment diagrams is one of the main contents of the study of chemical engineering drawings.
There are many kinds of chemical equipment, classification method has a variety of ways and means, for example, according to the structure of the material, can be divided into carbon steel equipment, stainless steel equipment, non-metallic equipment. According to the pressure can be divided into high-pressure equipment, medium-pressure equipment and vacuum equipment, atmospheric pressure equipment.

Chemical equipment should have the following properties:
(1) to have with the production of raw materials, products, intermediate products and other materials handled by the performance, quantity, process characteristics, production scale, etc.;
(2) a set of production equipment, regardless of the continuous and batch production, is composed of a variety of multiple equipment. Is composed of a variety of equipment, so the requirements of chemical equipment and other equipment with each other, equipment and piping, valves, instruments, meters, electrical circuits, etc., to have a reliable synergy and adaptability;
(3) the requirements of the chemical equipment on the normal temperature, pressure, flow rate, corrosive properties of the material operating conditions, in the structure of the material and the strength of the sealing performance and mechanical strength should be sufficient. The possible abnormalities, and even the possible extreme conditions to have enough to withstand and prevent, emergency and disposal capabilities;
(4) whether continuous or intermittent chemical production units need to be operated for a long time. Therefore, we should consider the chemical equipment wear and tear, corrosion and other factors, to ensure that there is a long enough normal service life;
(5) in order to meet the above conditions at the same time to optimize the chemical equipment materials, selection, manufacturing costs, efficiency and energy consumption, as far as possible to achieve the minimum;
(6) most of the various structures and performance of the chemical equipment is also suitable for use in industrial sectors, such as refining, light industry, food, etc., and therefore has a general purpose. Industrial sector use, and therefore has the generality.
