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.
