SS Seamless and Welded U Shaped Tube Suppliers, Have difficulty to find U-bend Tubes in tough sizes ? Call Raaj Sagar Steel Now

In comparison to straight tubes, U shaped or U bend tubes offer the end user the flexibility to build a more compact system. Typically used in heat exchanger applications, the Stainless Steel U Bend Tube is ideal for applications involving heat and elevated pressure levels. In environments where the temperature is extremely high, a straight tube would be connected using an expansion joint. Not considering thermal expansion for straight tubes would have a disastrous causal effect on the application.

Not forgetting to mention, the cost of using an expansion joint brings up the cost of the application. However, using a Stainless Steel U Bend Tube For Heat Exchanger for the connection of a tube and the shell permits thermal expansion of the component, without an upcharge or an increase in price. Hence, using the Stainless Steel U Shaped Tubes is not only efficient but also a cost effective solution. Although the design of the component is a vital aspect in terms of its application, selecting the appropriate grade in the manufacture of the Stainless Steel U Shaped Tube is the other important parameter. Today, one can find various grades of stainless steel available in the market.

From the very economical grade alloy 304 to the marine grade alloy 316, the use of any grade Stainless Steel Tube U Bend is limitless. And because the longevity of the application also comes into view, one of the most desirable alloys is the Ss 316ti U Bend Tubes, which contains titanium added in its chemical composition. The addition of titanium in the alloy improves the high temperature performance of the Stainless Steel Welded U Tube, especially because the alloy forms titanium carbide instead of carbide precipitates, which is not fatal to welded components.
