Bright Annealed Tube ASTM A249 TP304 StaInless Steel Welded Tube For Heat Exchangers

Bright Annealed Tube ASTM A249 TP304 StaInless Steel Welded Tube For Heat Exchangers

ASTM A249 TP304 stainless steel welded tubes are precision-engineered, longitudinally welded tubes specifically designed for heat exchanger applications. These tubes are manufactured from AISI304 stainless steel (equivalent to UNS S30400) in accordance with ASTM A249/A249M standard, which covers welded austenitic steel boiler, superheater, heat-exchanger, and condenser tubes. The "Bright Annealed" finish refers to a controlled atmosphere annealing process that results in a smooth, reflective, oxide-free surface without the need for subsequent pickling or passivation. The bright annealing process in particular provides significant advantages in terms of corrosion performance, cleanliness, and reduced maintenance, making these tubes suitable for critical applications across diverse industries. YUHONG GROUP has manufactured and provided ASTM A249 TP304 SS Welded Tubes for more than 30 years. These stainless steel welded bright annealed tubes are generally applied in heat exchangers, boilers, superheaters, and so on.
