ASME SA249 TP304/304L Stainless Steel Bright Annealed Welded Tube
GNEE is a leading manufacturer, supplier, and exporter of austenitic stainless steel pipes, utilizing materials compliant with ASTM A249 TP 304 standards, specifically designed for applications such as boilers, superheaters, heat exchangers, or condensers.
GNEE supplies high-quality welded stainless steel pipes conforming to ASTM A249 TP 304 standards, all of which undergo heat treatment while maintaining specified solution annealing temperatures and quenching methods. The production of ASME SA249 Gr 304L welded pipes involves rolling sheet or strip into shape, followed by a series of shop welding processes. While welded pipes exhibit lower strength compared to seamless pipes, they offer a more cost-effective solution. The A249 Type 304L ERW pipe is a unique variant manufactured using longitudinal welding technology. Additionally, we provide ASME SA249 Gr 304L bright annealed U-bend welded pipes and ASTM A249 TP 304 cold-drawn precision pipes.
