Structural principle

Tube heat exchanger, also known as column tube heat exchanger, consists of shell, heat transfer tube bundle, tube plate, baffle plate (or baffle rod), and tube box and other components. It is a partition heat exchanger with the wall of the tube bundle enclosed in the shell as the heat transfer surface.

◆ According to the form of the tube plate, shell, and their mating parts, they can be divided into fixed tube plate, floating headUThere are seven types: tube type, stuffing box type, kettle type, sliding tube plate type, and insertion tube type. ◆ According to the type of heat exchange tube, it can be divided into corrugated tube, spiral tube, threaded tube, copper smooth tube, low finned tube, string tube, brass, stainless steel smooth tube, transfer tube, etc. ◆ According to the installation form, it can be divided into two types: horizontal and vertical.

characteristic

This type of heat exchanger has a simple structure, reliable operation, and flexible selection of shell and tube materials according to the requirements of the medium. It can be used under high temperature and high pressure.

scope of application

Widely used in industrial sectors such as chemical, petroleum, petrochemicals, power, light industry, metallurgy, atomic energy, shipbuilding, aviation, heating, etc. Especially in petroleum refining and chemical processing facilities, it occupies an extremely important position. It is currently the most widely used heat exchange equipment.
