ASTM/ASME A/SA213 Seamless U Bending Steel Pipe And Tube For Boiler
U Bend Tube are manufactured in our plant as per the customer requirements. Solution annealing after bend will
be process to lower the risidual stress, and followed by hydrostatic testing and dye penetrant testing if required.
U Bend Tube are widely used in heat-exchanger systems. Heat exchanger equipment on the basis of stainless
steel U-tube is essential in strategically important and critical fields nuclear and petrochemical machine building.
