Stainless Steel U-tube Heat Exchanger
Basic Introduction
Stainless steel U-tube heat exchanger is a kind of shell and tube heat exchanger with a wide range of uses.
GNEE is an excellent stainless steel U-tube heat exchanger manufacturer with its own stainless steel U-tube heat exchanger factory, providing customers with a rich and certified product range covering various shapes, models and sizes to meet customer requirements.
Product Introduction
In a Stainless Steel U-tube heat exchanger, each tube is bent into a U shape. The fluid inlet and outlet are installed on both sides of the same end, and a partition plate is used to divide the head into two chambers.
Each tube can expand and contract freely to solve the problem of thermal compensation.
Utilizes a seamless and polished tube bundle.
Heating/cooling medium flows counter-currently through the shell side (outside the tubes).
Tubes are secured to the tube sheet flange.
Dual tube sheet design creates a leak detection zone, reducing cross-contamination risks between the two media.
Supports horizontal or vertical installation.
Product structure
- It consists of straight tubes bent into a U shape, terminating at both ends with a tube sheet.
- The tube bundle is equipped with a support or guide plate.
- The tube sheet/tube bundle is placed inside the shell and bolted between the head flange and the shell flange.
- A head assembly is required to guide the fluid in and out through the tube bundle.
- This structure allows the entire tube bundle to be removable.
Working principle
U-tube heat exchanger is a commonly used heat exchange equipment, and its working principle is based on heat conduction and fluid dynamics. Through the design of the U-tube, the heat exchanger is able to achieve indirect heat exchange between two different fluids. The U-tube heat exchanger achieves efficient heat conduction and fluid exchange through the unique U-tube design. Specifically, one fluid flows on one side of the U-tube, while the other fluid flows on the other side, and heat is exchanged through the tube wall
Product parameters

Product type
- 304 stainless steel U-tube heat exchanger: austenitic basic steel, widely used; excellent corrosion resistance and heat resistance; excellent low temperature strength and mechanical properties; single-phase austenitic structure, no heat treatment hardening phenomenon.
- 304L stainless steel U-tube heat exchanger: 304L is more corrosion-resistant and more high-temperature resistant than 304 stainless steel, and is particularly suitable for use in acidic and alkaline environments. The thermal performance is very stable, and the temperature rise and fall are particularly fast.
- 316 stainless steel U-tube heat exchanger: when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of heat exchangers, and the heat exchanger has strong corrosion resistance and ablation resistance.
- 316L stainless steel U-tube heat exchanger: strong resistance to intergranular corrosion, 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel
- 2205 stainless steel U-tube heat exchanger: high toughness, low brittle transition temperature, and significantly improved resistance to intergranular corrosion and welding performance.
- 2507 stainless steel U-tube heat exchanger: has the ability to resist corrosion, intergranular corrosion, and stress corrosion cracking, and can be used to make heat exchangers under special working conditions such as seawater heat exchangers and ship heat exchangers.
Product advantages
- The tube bundle design of the U-tube heat exchanger allows free floating, so there is no need to worry about temperature difference stress problems, which is particularly suitable for large temperature difference environments.
- The heat exchanger uses only one tube sheet, which reduces the number of flanges, reduces the risk of leakage, and simplifies the overall structure.
- The U-tube heat exchanger has won wide favor with its stable operating performance and economical cost.
