ASME SA249 TP304 Stainless Steel Welded Tube For Heat Exchangers
ASME SA249 TP304 Stainless Steel Welded Tube For Heat Exchangers
Specifications
ASTM A249 TP304 is a standard specification for welded austenitic stainless steel pressure tubes, most commonly made from 304 stainless steel. These tubes are used for high-quality applications like boilers, heat exchangers, and general industrial services, offering excellent corrosion resistance and strength. They can be manufactured using methods like ERW (Electric Resistance Welding) and TIG welding, and come in various sizes and surface finishes.
