U-Bend stainless steel tubes for heat exchanger
U-Bend stainless steel tubes for heat exchanger:
'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.
Tube-bending line, that will allow to produce U-tubes as per such standards:
1. ASTM A688/A688M-08
2. ASTM A803/A803M
3. ASTM A556/A556M, ASME SA-556
4. ASME SA-688
Initial Length:Maximum lengths of 27000mm can be supplied on request
Bending radius: Maximum 1000 mm
Heat treatment of the bend:U-bends with a bending radius up to maximum of 1000mm 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 bend Formed
5. Ultrasonic Test before U bend Formed
6. Heat treatment to stress relieved
7. Ball passing test
