[0002] U-tube manufacturing methods generally include: **Rolling Method:** No mandrel required, suitable for bending the inner edge of thick-walled U-tubes. Pressure is applied to the tube using rollers to gradually shape it. **Roller Method:** A mandrel is placed inside the tube, and rollers are used to push and press it from the outside to prevent deformation or breakage. **Inflation Method:** **Rubber Inflation Method:** Rubber is placed inside the tube, and a punch is used to compress and shape the tube. **Hydraulic Inflation Method:** Liquid is injected into the tube, and hydraulic pressure is used for shaping; commonly used for corrugated U-tubes. **Direct Bending Method:** A special U-shaped heat exchanger bending device is used. The tube is introduced along the groove of a rotating ferrule, and bending is completed by connecting the rotating ferrule and the fixed ferrule via a handle lever. Advantages: High bending quality and improved efficiency.
