Heating Equipment
The Shell-and-Tube Heat Exchanger (shell-and-tube heat exchanger) is one of the most widely used heat exchange equipment in the industrial field. It adopts a tube-shell structure design, with one side of the fluid flowing through the tube section and the other side flowing through the shell section. Heat is efficiently transferred through the tube wall. The equipment is structurally robust, resistant to high pressure and high temperature, and suitable for various complex working conditions.
This product is manufactured using high-quality carbon steel, stainless steel, or special alloy materials. The tube bundle is designed for disassembly, facilitating cleaning and maintenance, and meeting the heat exchange requirements of industries such as petrochemicals, power, refrigeration, and food processing.

Product features:
Efficient heat transfer
Optimized tube bundle arrangement and baffle design enhance turbulence, thereby increasing the heat transfer coefficient.
Supports various tube types (straight tubes, threaded tubes, low finned tubes), suitable for different viscosity media.
Reliable structure
Compliant with ASME, TEMA, and GB/T 151 standards, it has strong pressure-bearing capacity and excellent seismic performance.
With the floating head/U-tube design, it eliminates temperature difference stress and extends the service life of the equipment.
details
Product advantages:
Convenient Maintenance
The detachable tubes can be removed independently from the front and rear tube boxes, ensuring no cleaning blind spots.
Anti-vibration gaskets and expansion joints are provided to reduce the impact of vibration and thermal expansion.
Strong adaptability
Supports various phase changes such as gas-liquid, liquid-liquid, and gas-gas heat exchange.
Can withstand corrosive media including acids, alkalis, and salts.
Energy conservation and environmental protection
Counter-flow arrangement, with high utilization rate of temperature difference, reducing energy consumption.
Low-pressure drop design, lowering pump power consumption.
