There are many types of tube bending methods for different materials, environments, and designs. Most bending takes the form of elbow bends at different degrees or U-bends. Martensitic Stainless Steel:410(1.4006), 410S(1.4000), 420(1.4021)įerritic Stainless Steel :405(1.4002), 430(1.Tube bending uses metal-forming techniques to bend the material into precise layouts and shapes without crimping or weakening the metal. The below sizes are those most frequently used,other sizes can be produced upon request. High Pressure Hydrostatic Test:Minimum:10 Mpa-25Mpa.Ĥ. U-bends with a bending radius up to maximum of 1500mm can be heat treated on requestġ. Maximum lengths of 27000mm can be supplied on request Tube-bending line, installed at 2007, will allow to produce U-tubes as per such standards: U-Tube ends: plain, vertically cut to the tube axis Radius tolerance 1) for R 100 mm +/- 3 mm SW is smallest wall thickness D Nominal outside diameter R radius to TEMA RCB 2.31 Minimum tube wall thickness in the bend part (T min)T(min) ≥ (SW × (2×R + D))/( 2× (R+D)where: to TEMA R.C.B.įlattening (also called “ovality”) at the bend shall not exceed 10% of the nominal tube outside diameter. Surface condition Finished U-tubes shall be free of scale, without scratches after bendingĭimensional tolerances U-tubes acc. Thïs model is selected when differential expansion makes a fixed tube sheet exchanger unsuitable and when conditions preclude a floating head type (HPF) selection. U-tube heat exchangers Designed for high temperature applications, especially steam condensing or hot oil 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 bent tubes are widely used in heat-exchanger systems. Bends can be Heat Treated in accordance with Clients' requirements followed by hydrostatic testing and dye penetrant testing if required.

'U' Bend Stainless Steel Tubes are manufactured in our plant as per the customer requirements.
