Description
HDT specialized manufacturer of Stainless Steel Tubes for U Bend Tube Heat Ex-changer . Solution annealing after bend will be process to lower the residual stress, and followed by hydrostatic testing and dye penetrant testing if required.
Stainless Steel Tube are widely used in heat exchanger systems. Heat exchanger equipment on the basis of stainless steel tube is essential in strategically important and critical fields nuclear and petrochemical machine building.
Surface condition Finished Tube shall be free of scale, without scratches after bending
