ASTM B514 Welded Pipe

ASTM B514 specification covers Inconel 800 (UNS N08800) welded pipe whose outside diameter and nominal wall pipe shown in ANSI B36.19. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of the specification. Welded pipe shall be furnished with a scale-free finish. When bright annealing is used, descaling is not necessary. Pipe is capable of withstanding, without cracking, flattening under a load applied gradually at room temperature until the distance between the platens is five times the wall thickness. Welded pipe shall be made from flat-rolled alloy by an automatic welding process with no addition of filler metal. Subsequent to welding and prior to final solution treatment, the material shall be cold worked either in both weld and base metal or in weld metal only. The weld shall be positioned 90 deg from the direction of the applied flattening force.
