TEMA CERTIFIED U BEND TUBE HEAT EXCHANGER FOR REFINERY U STAMP
Yuhong Holding Group Co., Ltd is a globally recognized manufacturer and supplier of premium industrial equipment, including heat exchangers, fired heaters, air coolers, and related components. With decades of engineering expertise and cutting-edge manufacturing capabilities, we deliver high-quality solutions designed to meet the rigorous demands of industries worldwide.
A U-tube heat exchanger is a type of shell and tube heat exchanger where the tubes are bent into a "U" shape. Each tube bundle consists of many of these U-shaped tubes, and both ends of each tube are fixed to a single tube sheet. This design allows the tube bundle to expand and contract freely with temperature changes, making it highly resistant to thermal stress.
U-Tube VS. Straight-Tube Heat Exchanger
| Feature | U-Tube Heat Exchanger | Straight-Tube Heat Exchanger |
| Thermal Expansion | Free-floating; handles it very well. | Fixed at both ends; requires an expansion joint in the shell for large ΔT. |
| Tube Sheets | One | Two |
| Internal Cleaning | Difficult (chemical only). | Easy (can be rodded or brushed). |
| Tube Replacement | Difficult (often requires new bundle). | Possible to replace individual tubes. |
| Cost | Generally lower. | Generally higher. |
Tube heat exchanger key Features:
1. Structure:
Shell: The large outer vessel that contains one fluid (the "shell-side fluid").
U-Tubes: A bundle of tubes bent into a U-shape. A second fluid (the "tube-side fluid") flows through these.
Tube Sheet: A single, thick metal plate drilled with a precise pattern of holes. Both the inlet and outlet legs of the U-tubes are attached to this same tube sheet.
Stationary Channel/Head: The chamber at the front where the tube-side fluid enters and exits. It contains a crucial part called the bonnet or head, which is split by a partition (baffle). This partition directs the incoming fluid into the tubes and keeps it separate from the outgoing fluid.
Baffles: Plates placed inside the shell. They serve two main purposes:
They support the long, U-shaped tubes to prevent vibration.
They force the shell-side fluid to flow back and forth across the tube bundle, increasing heat transfer efficiency.
Tube heat exchanger advantages:
- High Efficiency: Suitable for large temperature and pressure differentials.
- Durability: Robust construction handles harsh conditions (high pressure/temperature, corrosive fluids).
- Scalability: Modular designs accommodate varying capacities.
- Maintenance: Tube bundles can be easily cleaned or replaced.
Type of Heat exchanger tube:
U-bend & Straight.
