"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.
Stainless Steel U tube 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.
