ASTM A213 TP317L U Bend Tube

Product Attributes

U-bends are widely used in heat exchanger systems. Heat exchange equipment is based on

Seamless stainless steel U-tubes and welded stainless steel U-bends are of strategic importance and

Key areas --- nuclear petrochemical machinery manufacturing.

YUHONG Group 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.
