Introduction
Shell and Tube Heat Exchanger is one of the most widely used heat exchange devices in the chemical industry. It transfers heat from one fluid to another through the tube wall, achieving process requirements such as heating, cooling, condensation, or evaporation. Its core structure consists of tube bundles (heat transfer tubes), shells, tube sheets, baffles, and heads, which have the characteristics of strong adaptability, high pressure and high temperature resistance, and easy maintenance, especially suitable for complex working conditions in chemical production.
Typical applications
Petroleum refining and petrochemical processing
Preheating of crude oil
Heating the crude oil before the distillation tower to improve separation efficiency
Product condensation
Condensing cracked gas into liquid hydrocarbons ,ethylene, propylene, etc

Polymer and plastic manufacturing

Temperature control in polymerization reactions
removing reaction heat in the production of polyethylene and polypropylene to prevent local overheating and side reactions.
Melt cooling
Cooling the high-temperature polymer melt to the molding temperature
