Technical Specifications of Packed Floating Head Heat Exchanger​

The ​​Packed Floating Head Heat Exchanger​​ is a ​​removable tube bundle heat exchanger​​ under TEMA standards, featuring a ​​packed floating head design​​ for ​​high-temperature, high-pressure, and fouling-prone applications​​. It is particularly suitable for industries requiring frequent cleaning, such as chemical, petroleum, and pharmaceuticals. Below are its core technical parameters:

1. Key Technical Parameters​

2. Structural Features

• o Packed Floating Head​​ – Dynamic sealing via packing gland to accommodate thermal expansion.
• o Removable Tube Bundle​​ – Entire bundle can be extracted for mechanical/chemical cleaning.
• o Thermal Stress Resistance​​ – Floating head compensates for differential expansion between tubes and shell.
• o Multi-Pass Configuration​​ – Tube side can be single-pass, 2-pass, or multi-pass (2/4/6 passes).

3. Typical Applications

• o Petrochemicals​​: Heavy oil heating, cracked gas cooling
• o Chemical Processes​​: High-viscosity fluid heat exchange, polymer solution handling
• o Pharma/Food​​: High-sanitation applications (CIP/SIP systems)
• o Power Industry​​: High-pressure steam condensation

4. Data Required for Selection

• o 1.Fluid Properties​​ ​​(viscosity, corrosiveness, fouling tendency)
• o 2.Temperature & Pressure​​​​ (operating temperature, design pressure)
• o 3.Cleaning Frequency​​​​ (determines packing maintenance intervals)
• o 4.Thermal Expansion​​ ​​(affects packing gland selection)

5. Advantages

• o High-Pressure Suitability​​ – Packing seals withstand ≤10 Mpa.
• o Easy Maintenance​​ – Tube bundle can be extracted without shell disassembly.
• o High-Temperature Resistance​​ – Graphite/metallic packing tolerates up to 500°C.
• o Long Service Life​​ – Regular packing replacement extends operational life.
