What is ASTM A213 material?

ASTM A213 is a specification for seamless ferritic and austenitic alloy steel tubes used in high-temperature applications like boilers, superheaters, and heat exchangers. It covers grades such as T1, T2, T5, T9, T11, T22, and T91, ensuring thermal stability and mechanical strength.

What size is ASTM A213 tubing?

ASTM A213 tubing is available in outer diameters ranging from 6.35 mm to 101.6 mm, with wall thicknesses typically between 0.8 mm and 12.7 mm. Custom lengths, diameters, and thicknesses can also be provided based on project specifications or industry requirements.

What is SA213 T2 material?

SA213 T2 is the ASME equivalent of ASTM A213 T2, a seamless ferritic alloy steel tube with molybdenum content for improved strength and thermal resistance. It is designed for use in boilers, superheaters, and heat exchangers operating under high-temperature and high-pressure conditions.

What is the difference between ASTM A213 and A269?

ASTM A213 covers seamless alloy and stainless steel tubes for high-temperature services, while ASTM A269 covers welded and seamless stainless steel tubing for general corrosion-resisting and low- or high-temperature service. A213 is used more for boiler and heat exchanger tubing.

What is ASTM A269 tubing?

ASTM A269 tubing refers to seamless or welded austenitic stainless steel tubes designed for general corrosion-resistant applications. Commonly used in instrumentation, chemical, and food processing industries, these tubes offer excellent strength, durability, and corrosion resistance.

Applications of ASME SA213 T2 Tubing

A213 T2 Boiler Tubes in Power Plants

ASTM A213 T2 Boiler Tubes are widely specified in coal-fired and combined-cycle power plants for superheater and reheater assemblies operating at metal temperatures up to 510°C (950°F). The 0.5Cr-0.5Mo chemistry delivers superior creep resistance over plain carbon steel at sustained elevated temperatures, making T2 the economic first step in the chrome-moly alloy family. For higher-temperature service beyond T2's limits, see ASTM A213 T11 Tubes (1.25Cr-0.5Mo) and ASTM A213 T22 Tubes (2.25Cr-1Mo).

SA213 T2 Heat Exchanger Tubes in Refineries

ASME SA213 T2 Tubing is used in crude oil pre-heaters, atmospheric distillation overhead condensers, and hydrocracker feed/effluent exchangers in petroleum refineries. T2's moderate corrosion resistance suits naphthenic acid and hydrogen sulfide-containing streams at sub-critical temperatures. For higher-severity refinery service, ASTM A213 T5 Tubes (5Cr-0.5Mo) or T9/T91 grades are recommended. Browse our full range: High-temperature Boiler Tubes & Pipes.
