ASTM A249 TP304L Stainless Steel Welded Tube Heat Exchanger Tube
GNEE brings 18 years of stainless steel production and export expertise, ensuring rigorous quality control with manufacturer's warranty and third-party inspection reports to guarantee reliable tube quality. Our solutions provide stable, high-performance options for heat exchange applications in chemical, power, and food industries.
GNEE supplies high-quality ASTM A249 TP304L stainless steel welded tubes (heat exchanger tubes), a low-carbon variant of 304 stainless steel containing 18% chromium and 8% nickel. This grade delivers exceptional corrosion resistance against diverse chemical media, along with superior toughness and weldability. It is suitable for high-temperature and high-pressure environments, making it ideal for heat exchangers, condensers, and similar equipment.
The ASTM A249 TP304L stainless steel ERW tubes are available in multiple specifications to meet diverse project dimensional requirements. Surface treatments such as polishing and pickling are offered to suit specific application needs. These tubes are typically supplied in the annealed condition. Post-weld heat treatment may be required to restore corrosion resistance and mechanical properties. They undergo various tests, including hydrostatic testing or non-destructive electrical testing, to ensure compliance with specified standards. Tubes are generally delivered with certificates conforming to ASTM A249 requirements.
