Stainless Steel U Bent Tubes are manufactured usually as per the customer's requirements.


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. This 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.


Standard Specification of Straight Tubes For Bending:


ASME SA 213; ASME SB 163; ASME A789, ASME SA269, ASTM A 213, ASTM A 312, etc.


Technical parameters of U bend pipes: 



OD 9.3 - 38 mm


Bending radii from 1.5 x OD up to 1,250 mm. Minimum bending radii for OD over 28 mm after agreement.


Leg length min. 1,000 mm.


Leg length max. 12,000 mm.


Heat treatment for radii up to 1,000 mm.



Stainless steel u bent tubes usually are supplied as boiler tubes


and heat exchanger tubes.
