Heat Exchanger Tube, ASTM A213 TP304L(UNS S30403) Stainless Steel Seamless U Bend Tube
ASTM A213 TP304L grade covers standard specifications for boilers, heat exchangers, and superheated vessels. The ASTM A213 TP304L Tube is a low-carbon austenitic grade with a superior composition of nickel and chromium, making this tube work well in corrosive and oxidative media. The ASTM A213 TP304L Stainless Steel Tube can work in high-temperature applications for a long time. This tube has excellent surface quality and has very low levels of sensitization in the system.
Stainless Steel U Bend tubes are widely used in heat exchanger systems. Heat exchanger equipments which are on the basis of seamless stainless U tubes are essential in fields like nuclear and petrochemical machine building. Stainless Steel U tube heat exchangers designed for high temperature applications, especially for steam condensing or hot oil systems.
