Floating Tube Bundle Heat Exchanger
Engineered for High-Temperature, High-Fouling, and High-Thermal-Stress Applications
Floating tube heat exchangers are specifically designed for process conditions where large temperature differentials, high fouling tendencies, and frequent maintenance requirements are present. The floating tube design allows the tube bundle to expand and contract freely inside the shell, eliminating thermal stresses that occur in fixed designs. This results in improved reliability, extended service life, and easier maintenance.
Manufactured to stringent international standards, our floating tube bundle heat exchangers deliver dependable thermal performance in continuous, demanding industrial operations.
Overview of the Floating Tube Bundle Design
A floating tube bundle heat exchanger—commonly produced in TEMA Types F, P, or W—features one fixed tubesheet and one floating tubesheet. This configuration allows the bundle to move axially within the shell, accommodating:
- Large temperature differences between shell and tube sides
- Thermal expansion without mechanical stress or deformation
- Easy removal of the bundle for inspection and maintenance
This makes the floating tube design a preferred solution for high-temperature and fouling-prone processes.
Key Engineering Features
Floating tubesheet for thermal expansion control
Eliminates stress-related failures and increases operational durability.
Fully removable tube bundle
Allows efficient mechanical cleaning, particularly beneficial for fouling services.
High mechanical integrity
Designed for elevated pressures and temperatures.
Optimized tube configuration

Manufactured to global codes and standards
Including TEMA, ASME Section VIII, and customer-specific requirements.
How the System Operates
During operation, the temperature difference between shell-side and tube-side fluids causes thermal expansion.
In fixed tube exchangers, this can result in stress and premature failure.
The floating tube bundle design prevents this by allowing:
- Axial movement of the bundle
- No mechanical stress on tubes or tube sheets
- Higher allowable temperature differences
- Improved operational safety and longevity
This makes the design suitable for severe process conditions.
Typical Industrial Applications
Floating tube bundle heat exchangers are used extensively in:- Petrochemical plants
- Refining and process industries
- Chemical production units
- Fertilizer and ammonia plants
