ASME SA249 Bright Annealed Stainless Steel 304 Welded Tube For Distiller , 3 / 4" 20BWG
ASME SA249 TP304 Bright Annealed Welded Tube is a austenitic stainless steel tube intended for use in heat exchangers, condensers, and similar heat transfer apparatus. It is manufactured from TP304 grade material, welded longitudinally, and then subjected to a final heat treatment process known as "Bright Annealing" in a controlled atmosphere furnace. This stainless steel welded tube is a high-quality welded tube designed for applications demanding excellent corrosion resistance, good mechanical properties, and a superior surface finish. The "Bright Annealing" process is key to its performance. After welding, the tube passes through a furnace with a controlled atmosphere (typically hydrogen, nitrogen, or a vacuum) at temperatures exceeding 1900°F (1040°C). YUHONG GROUP has supplied ASTM A249/ASME SA249 stainless steel welded tubes for many years and has abundant manufacturing experience. We can provide such welded tubes from 6mm to 152.4mm diameter. The length can be 35 meter maximum.
