ASTM A249 TP304 Stainless Steel Welded Tube introduction
ASTM A249 TP304 stainless steel welded pipe has excellent high temperature oxidation resistance (up to 870℃), intergranular corrosion resistance and high pressure bearing capacity through precision welding and solution heat treatment. It is widely used in core equipment such as power station boilers, chemical reactors, heat exchangers, etc. It is a reliable choice for industrial high temperature and high pressure piping systems.

Advantages of ASTM A249 welded pipes
TP304 stainless steel welded pipe is subjected to 1040-1100℃ solid solution treatment after welding to eliminate welding stress and restore the uniformity of austenite structure. The high temperature tensile strength is ≥515MPa (retention rate ≥90% at 100℃), the wall thickness range is 0.5-12.7mm, the pressure level covers Sch 5S to Sch 160, and it has passed the water pressure test (1.5 times the design pressure, no leakage). The long-term service temperature is -196℃~870℃, suitable for power station boiler superheaters (steam temperature ≤540℃) and industrial furnace high temperature gas pipelines.
