U-Bend stainless steel tubes for heat exchanger
'U' Stainless Steel Tubes are manufactured in our plant as per the customer requirements. B

'U' 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 stainless steel tubes are widely used in heat-exchanger systems. Heat exchanger equipment on the basis of seamless stainless U-tubes 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. This model is selected when differential expansion makes a fixed tube sheet exchanger unsuitable and when conditions preclude a floating head type (HPF) selection.
Tube-bending line, installed at 2007, will allow producing U-tubes as per such standards:
1. ASTM A688/A688M-08
2. ASTM A803/A803M
3. ASTM A556/A556M, ASME SA556
4. ASME SA-688
Initial Length
Maximum lengths of 27000mm can be supplied on request
Dimensions
Tubes OD in mm can be bent upon agreement: 15,8 - 16,0 - 17,0 - 18,0 - 19,05 - 20,0 - 21,3 - 25,4 -26,7 - 31,8 -38,1
Bending radius
Minimum 1.5×OD
Maximum 1500 mm
Heat treatment of the bend
U-bends with a bending radius up to maximum of 1500mm can be heat treated on request
The basic Testing and processing:
1. High Pressure Hydrostatic Test: Minimum:10 Mpa-25Mpa.
2. Air under Water Test after Bending
3. U Tubes Wall Thickness Test
4. Eddy Current Test before U bends Formed
5. Ultrasonic Test before U bend Formed
6. Heat treatment to stress relieved
7. Ball passing test
The below sizes are those most frequently used, other sizes can be produced upon request.
The dimensions for heat exchanger tubes in special grades may differ from the above, please contact us.
