ASTM A249 904L Welded Tubes

ASTM A249 UNS N08904 Duplex Steel 904L Welded Heat-Exchanger and Condenser Tubes

 Seamless tube is extruded and drawn from a billet while welded tube is produced from a strip that is roll formed and welded to produce a tube.

Welded tube is considerably less expensive than seamless tube and is readily available in long continuous lengths.

Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam.

The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond.
