ASTM A249 TP304 Bright Annealed Stainless Steel Welded Tube Heat Exchanger Tube
ASTM A249 is a standard specification for welded austenitic stainless steel such as TP304/ 304L/ 316L ... tubing intended for use in boilers, heat exchangers, and similar applications. The tubing is produced by a welding process, usually using a continuous welding method. This results in a smooth interior surface, which is important for flow characteristics in heat equipments. ASTM A249 includes specific testing requirements to ensure the integrity of the tubing. This can include hydrostatic testing, eddy current testing, and non-destructive testing methods to check for leaks and other defects.
