Product Overview
The U Tube Type Heat Exchanger adopts a U-shaped tube bundle design, where the heat exchange tubes are bent into a U configuration and fixed on one tube sheet side. This structure allows free thermal expansion without requiring a floating head sealing system, providing a simple structure and reliable pressure resistance.
The equipment supports a design pressure range of 0.8~10MPa and operating temperature range of -40℃~400℃. The heat transfer area can reach 2~1000㎡. The shell and tubes can be manufactured using carbon steel, chrome-molybdenum heat-resistant steel, 304 stainless steel, 316L stainless steel, or duplex stainless steel according to application requirements.
The tube side is suitable for high-pressure media, while the shell side is designed for cleaner fluids. The removable tube bundle simplifies maintenance. Each unit undergoes independent shell-side and tube-side pressure testing before delivery.
The equipment complies with GB151 heat exchanger standards and ASME VIII.1 requirements, with a designed service life of 15~30 years.
Core Advantages
- U-shaped tube bundle structure eliminates expansion joints and floating seals, reducing leakage points in high-pressure applications.
- Removable tube bundle design allows convenient cleaning and maintenance of internal tube surfaces.
- Excellent high-temperature and high-pressure adaptability, suitable for steam recovery and thermal oil systems.
- Compact structure reduces installation space requirements compared with floating head designs.
Applications
- Power plant waste heat recovery systems
- Thermal oil heating and cooling systems
- High-pressure chemical fluid heat exchange
- High-temperature steam cooling equipment
- New energy MVR systems
- Chemical processing heat exchange units
Manufacturing Advantages
The factory is equipped with dedicated U-bending machines and CNC tube sheet drilling equipment. Tube bundle welding adopts automated argon arc welding technology, and each high-pressure tube bundle undergoes individual leakage testing.
With experience in multiple high-pressure heat exchanger projects, the company can provide stress analysis reports for high-temperature steam and thermal oil applications.
All tube materials are supplied with original manufacturer certificates and undergo optical spectrum inspection upon arrival to ensure material reliability.
The company holds complete pressure equipment manufacturing qualifications and can undertake customized domestic and international heat exchanger projects.
