Product DescriptionTypes of tubular heat exchangersTubular heat exchangerA tubular heat exchanger is a common heat exchange device, primarily consisting of a tube bundle, tube sheet, and shell. Hot and cold fluids flow inside and outside the tubes, respectively, exchanging heat through the tube walls. Its advantages include a simple structure, resistance to high temperatures and high pressures, and a wide range of applications, particularly for high-viscosity fluids and those containing solid particles. However, tubular heat exchangers have relatively low heat transfer efficiency, require a large floor space, are difficult to clean, and are prone to scaling, which can affect heat transfer. They are widely used in industries such as the chemical, petroleum, and power generation industries.Stainless steel tubular heat exchangerCarbon steel tubular heat exchangerTitanium tube heat exchangerChemical IndustryHandles moderately corrosive chemicals.Petrochemical IndustryProcessing high-temperature, high-pressure fluids.Chemical IndustryUsed for handling corrosive chemicals.Pharmaceutical IndustryMeets hygiene and corrosion resistance requirements.Power IndustryUsed in power plant cooling systems.Pharmaceutical IndustryMeets hygiene and corrosion resistance requirements.Food IndustryUsed for heating and cooling in food processing.Iron and Steel IndustryRecovering waste heat to improve energy efficiency.Food IndustryEnsures hygie nic safety during food processing.Paper IndustryTreats pulp and wastewater.Heating, Ventilation, and Air ConditioningUsed for heating and cooling large buildings.Marine EngineeringSuitable for high-salinity seawater environments.Textile IndustryUsed in dyeing and rinsing processes.Food ProcessingUsed for heating or cooling non-corrosive materials.Environmental Protection IndustryTreats acidic or alkaline wastewater.Features of Tubular Heat Exchangers1.Simple Structure: Consisting of basic components such as the tube bundle, tube sheet, and shell, it is relatively simple to design and manufacture.2.High Temperature and High Pressure Resistance: Able to withstand high operating pressures and temperatures, suitable for a variety of harsh operating conditions.3.Wide Application: Suitable for high-viscosity fluids and fluids containing solid particles, with strong adaptability.4.Stable Operation: Robust structure, reliable operation, and long service life.5.Low Heat Transfer Efficiency: Compared with plate heat exchangers, it has lower heat transfer efficiency and requires a larger heat transfer area.6.Large Footprint: The equipment is larger and occupies more space.7.Difficult to Clean: Tubes are prone to scaling, making cleaning and maintenance more complex.8.Low Cost: Initial investment cost is relatively low, but long-term energy consumption is higher.9.Low Flexibility: The fixed structure makes it difficult to adjust the heat transfer area according to needs. 10.Limited Corrosion Resistance: Material options are limited, and appropriate materials must be selected based on the fluid's characteristics.These characteristics make tubular heat exchangers widely used in industries such as the chemical, petroleum, and power generation industries, particularly those requiring high equipment stability and pressure resistance.System composition1.Tube bundle: Consists of multiple heat exchange tubes arranged in parallel, serving as the primary heat exchange site. The fluid inside the tubes exchanges heat with the fluid outside through the tube walls.2.Tube sheet: Secures the tube bundle, securing the ends of the heat exchange tubes to the tube sheet to prevent vibration or displacement under fluid impact.3.Shell: Encloses the tube bundle, creating a flow space for the shell-side fluid. The shell is typically cylindrical, with end caps.4.End caps: Installed at each end of the shell, they seal the shell and create inlet and outlet ports for the fluid. End caps are typically elliptical or spherical to withstand high pressures.5.Baffles: Installed within the shell, they redirect the shell-side fluid flow, increasing turbulence and improving heat transfer efficiency.6.Inlet and outlet nozzles: Connect to external piping, directing fluid flow into and out of the heat exchanger. These nozzles are typically welded to the end caps.7.Support structure: Supports the tube bundle to prevent vibration or deformation during fluid flow. The support structure typically includes longitudinal and transverse supports. 8.Sealing elements: used to prevent fluid leakage, usually including flange gaskets, tube sheet gaskets, etc. The material of the sealing element should be selected according to the characteristics of the fluid and the operating temperature.Company ProfileQingdao Conqinphi Environmental Technology Group Co., Ltd.
