\"U\" Stainless Steel Tubes are manufactured in our plant as per the customer requirements. Bend can be Heat Treated in accordance with Client\'s Requirements followed by hydrostatic testing and dye penetrant testing if required.
U-bend 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 petro-chemical machine building.
Utube heat exchangers Designed for high temperature applications,especially for 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.
