Product Overview

Wuxi Yiteng Pressure Vessel Co., Ltd. manufactures U Tube Bundle Heat Exchanger solutions designed for industrial applications requiring thermal expansion flexibility, high-pressure operation, and reliable heat transfer performance.

The U tube structure allows each tube to expand independently under temperature changes, reducing thermal stress and improving equipment reliability during continuous operation.

Yiteng provides customized U tube bundle manufacturing for chemical, petrochemical, energy, and industrial process equipment manufacturers worldwide.

Manufacturing Advantages

1. Superior Thermal Expansion Compensation Design

Temperature differences between shell and tube sides may cause different expansion rates during operation.

The U tube structure provides natural expansion compensation through:

✓ U-shaped tube design
✓ Reduced thermal stress concentration
✓ Improved fatigue resistance
✓ Stable operation under temperature cycling

Suitable for applications involving:

• High temperature processes
• Steam systems
• Thermal oil systems
• Continuous industrial operation

2. Precision U Tube Manufacturing Capability

U tube bundle production requires strict control of tube forming accuracy.

Yiteng applies professional manufacturing processes:

• Tube bending control
• Tube radius inspection
• Tube sheet machining
• Tube expansion
• Tube-to-tubesheet welding
• Bundle assembly

Ensuring accurate tube geometry and reliable sealing performance.

3. High-Performance Material Solutions

Different operating conditions require different tube materials.

Yiteng manufactures U tube bundles using:

Stainless Steel

• 304
• 316L

Duplex Materials

• Duplex Stainless Steel
• Super Duplex Stainless Steel

Special Alloys

• Titanium Alloy
• Hastelloy C276
• Nickel-Based Alloy

Suitable for:

✓ Corrosive fluids
