ASTM A269 ASTM A213 TP 316 U Bend Stainless Steel Seamless Tube Coil Tubing Heat Exchanger Tube Oil Industry
U-Bend Tubes are widely used in Heat Exchanger Systems. Heat-Exchanger Equipment on the basis of Seamless Stainless U-Tubes and Welded Stainless U bend Tube is essential in strategically important and critical felds---Nuclear And Petrochemical Machine Building. YUHONG SPECIAL STEEL Start to Produce U Bending Tube Since 2006,Up to now already supply more than 30000 tons Stainless Steel U Bend Tube to 35 countries.
SS316l seamless u tubes are formed with an excellent and qualitative range of stainless steel. These tubes consist of various attributes and fabrication that provide excellent corrosion resistance to critical atmospheric conditions. The national and international quality of raw material is required for the formation of these seamless u tubes. The product is being carried out for all the industrial applications also. The product consists of superior and excellent quality by implementing highly skilled technicians in manufacturing processes.
