ASME SA213 Stainless Steel Seamless TP304L Bend U Boiler Tube

ASME SA213 Stainless Steel Seamless TP304L Bend U Boiler Tube

YuHong can offer SA213/A213 seamless stainless steel bend U tubes and we sell these products with highest quality in more than 70 countries.

ASME SA213 / ASTM A213 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc.

U tubes are manufactured by bending straight tubes. Bending is done cold on an automatic U-bend. To ensure tube wall thinning and diameter ovality are controlled, tube bending is accomplished with a mandrel inserted into the tube. What's more, the U-bend of the U-tube is stress relieved under controlled conditions and cycles for extended life.
