ASTM A249/ASME SA249 TP304 Welded Stainless Steel Tube

--High-Quality Austenitic Stainless Steel Tubing for Heat Exchanger and Boiler Applications

ASTM A249/ASME SA249 TP304 stainless steel welded pipe is suitable for heat exchangers, boilers and other equipment under high temperature and high pressure, and has excellent corrosion resistance and welding performance.

ASTM A249/ASME SA249 TP304 is a stainless steel welded pipe widely used in industrial equipment such as heat exchangers, boilers, condensers, etc. It is one of the standards for austenitic stainless steel pipes. This standard is mainly for austenitic stainless steel heat exchanger pipes used after welding, cold working and annealing, emphasizing the corrosion resistance, mechanical strength and forming performance of the product under high temperature and high pressure environment.

TP304 is one of the most common austenitic stainless steel grades, with good corrosion resistance, weldability and processing performance. Its chemical composition contains 18% chromium and 8% nickel, which makes it show stable corrosion resistance in most corrosive media, especially suitable for mild to moderate corrosive environments. The ASTM A249 standard has extremely high requirements for the quality control of welds. The welds must be 100% eddy current tested or other non-destructive testing methods to ensure the reliability of welding quality.

This type of pipe usually uses electric resistance welding (ERW) or plasma welding + tungsten inert gas welding (PAW+GTAW) to achieve stable consistency of internal and external welds. It is also necessary to undergo cold processing shaping, solution annealing, pickling and passivation treatment to improve the mechanical properties and corrosion resistance of the pipe body.

TP304 welded stainless steel pipes are widely used in petrochemical, food and beverage, seawater desalination, medicine, pulp and paper, shipbuilding and other fields, especially in working conditions requiring high cleanliness, stability and pressure resistance. At the same time, the product also meets the requirements of the ASME pressure vessel specification and can be used in pressure piping systems.
