Product Description
ASTM A249 / ASME SA249 TP316 weld Tube For Low to Medium Pressure Heat Exchanger and General Fluid Transport Systems
Overview
ASTM A249 / ASME SA249 specifies welded austenitic steel tubes for boilers, superheaters, heat exchangers, and condensers.
For applications requiring high resistance to intergranular corrosion, TP316L is generally recommended due to its lower carbon content (≤0.03%), which effectively improves the corrosion resistance of the welded joints.
ASTM A249 / ASME SA249 TP316 weld tubes, while ensuring good corrosion resistance and sufficient high-temperature strength, offer advantages over seamless tubes, including lower cost, more uniform wall thickness, and shorter delivery times.
| Dimension | Welded Tube (A249 TP316) | Seamless Tube ( A213 TP316) |
| Typical Applications | Heat exchangers, condensers, low-pressure piping, general fluid transport, food processing equipment. | Boilers, high-pressure superheaters, nuclear power piping, petrochemical high-temperature and high-pressure pipelines, hydraulic systems. |
| Pressure Rating | Suitable for low to medium pressure conditions (typically used in Class 300 and below). | Suitable for high-pressure and ultra-high-pressure conditions. |
| Medium Requirements | Suitable for general corrosive media. | Suitable for extremely harsh corrosive media or applications with high safety requirements. |
| Size Range | Dominant in small to medium diameters; offers significant advantages for large-diameter pipes. | Dominant in small-diameter, thick-wall pipes; production of large-diameter seamless pipes is limited by piercer capacity. |
