Stainless Steel U Bend Tube ASME SB 163, ASME SA213 ASTM A688 for Heat Exchanger Systems
U-Bend Tube 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.
Zhejiang Yuhong Steel Start to Produce U Bending Tube Since 2006,Up to now already supply more than
25000 tons Stainless Steel U Bend Tube to 30 countries.
The U-Bend Tube Comply With The Following Standards:
