ASTM A249 TP304 Stainless Steel Welded Tube For Boiler

304-grade stainless steel is the most widely used commercial stainless steel, serving numerous industries and also known as WNR 1.4301 welded pipe. ASTM A249 304 stainless steel welded pipes exhibit excellent corrosion resistance under normal atmospheric conditions, are easy to process and weld, and ASTM A249 304 welded condenser pipes maintain their strength and toughness even at sub-zero temperatures.

 

GNEE supplies ASTM A249 TP304 stainless steel welded pipes (for boiler applications). This material is an austenitic chromium-nickel stainless steel, manufactured by coiling and welding steel strips or plates through automated welding processes (such as high-frequency welding/ERW, TIG welding, etc.), followed by solution heat treatment (heating to 1040–1150°C and then rapid cooling). These pipes offer a cost advantage over seamless pipes and are widely used in power plant boiler piping, industrial heat exchanger connection pipes, chemical high-pressure fluid conveying systems, and marine steam systems, particularly for medium-to-high pressure applications where post-weld heat treatment or radiographic inspection is not required.

ASTM A249 TP304 stainless steel pipe undergoes bright annealing and annealing pickling to remove scale and clean the inner and outer surfaces. Heat treatment in a closed furnace, using inert hydrogen, increases the roughness of the pipe and makes it brighter, making it easier to clean when installed in heater and cooler systems.
