Standard: ASTM A213 / ASME SA213
Type: seamless, cold-drawn or hot-finished
Size Range: typically 1/8" to 5" OD, with wall thicknesses per schedule requirements
Length: random or cut lengths up to 12 meters, required by clients
Wall Thickness: generally min. wall thickness
Maximum Service Temperature: 650°C (1200°F)
T5 tubes have good oxidation resistance and creep strength, which maintains structural integrity under prolonged stress at high temperatures.
Applications
Power Generation: Superheater and reheater tubes; Boiler convection passes; Steam headers and manifolds
Petrochemical: Furnace tubes in cracking units; Heat exchanger tubing; Catalytic reformer components
Industrial Processing: Thermal fluid systems; Heat treatment furnace components; High-temperature gas ducts
In future, more increasing demand for higher efficiency power plants, more T5 tubes to be used. And due to the development of improved welding techniques for Cr-Mo alloys and the growing applications in renewable energy thermal storage systems, ASTM A213 T5 tubes also remain a preferred choice for critical high-temperature applications across multiple industries.
