U-Bend Stainless Steel Tubes Package
‘U’ Bend Stainless Steel Tubes are manufactured in our plant as per the customer requirements. Bends can be Heat Treated in accordance with Clients’ requirements followed by hydrostatic testing and dye penetrant testing if required.
U bent tubes are widely used in heat-exchanger systems. Heat exchanger equipment on the basis of stainless U-tube is essential in strategically important and critical fields nuclear and petrochemical machine building.
U-tube heat exchangers Designed for high temperature applications, especially steam condensing or hot oil systems. Thïs model is selected when differential expansion makes a fixed tube sheet exchanger unsuitable and when conditions preclude a floating head type (HPF) selection.
Surface condition Finished U-tubes shall be free of scale, without scratches after bending

Basic testing and processing:
- High-pressure hydrostatic test: minimum: 10 Mpa-25Mpa.
- Underwater air test after bending
- U-tube wall thickness test
- Eddy current test before U-shaped bend is formed
- Ultrasonic test before U-shaped bend is formed
- Heat treatment can relieve stress
Other details of U bend tube:
- Cut all the pipes to the specified leg length, and use air for internal cleaning and deburring.
- Before packaging, both ends of the U-shaped elbow are covered with plastic covers.
- Vertical separator for each radius.
- Each plywood box is equipped with a packing list covered with plastic to facilitate identification of order details, including an accurate list of internal radius and length.
