The U-tube heat exchanger is a high-efficiency, compact shell-and-tube heat exchanger designed for demanding thermal applications. The tube bundle is bent into a U-shape with both ends fixed on a single tubesheet, effectively eliminating thermal stress caused by large temperature differences between the tube-side and shell-side fluids.
Key Features:
Excellent Thermal Compensation: The U-bend design allows free expansion of the tube bundle, eliminating the need for expansion joints.
Compact and Cost-Effective: Simpler construction than floating-head types reduces manufacturing and maintenance costs.
High Pressure and Temperature Capability: Designed for pressures up to 10.0 MPa (per GB/T 28712.3-2023) and temperatures up to 350°C.
Easy Shell-Side Cleaning: The pull-through bundle design allows convenient access for shell-side mechanical cleaning.
Reliable Tube-to-Tubesheet Joints: Options include expansion, welding, or combined expansion-welding to suit various media and operating conditions.
