The ASTM A209 Grade T1 Seamless Steel Tubes are designed to meet the requirements of a wide range of industries including petrochemical, oil and gas, and power generation. These tubes offer minimum-wall-thickness, seamless, carbon-molybdenum alloy-steel that are suitable for use in boiler and superheater applications.
The tubes are made to ASTM A209 standards which specifies the requirements for seamless carbon-molybdenum alloy-steel boiler and superheater tubes. These tubes have an outer diameter ranging from 10mm to 203mm and a wall thickness ranging from 2.0mm to 25mm. The length can vary from 5.8m to 12m based on your specific needs.
The ASTM A209 is a standard specification for seamless carbon-molybdenum alloy-steel boiler and superheater tubes. This specification specifies the dimensions, materials, and technical requirements for these tubes.
The ASTM A209 specification covers grades T1, T1a, and T1b.
The tubes specified in ASTM A209 are produced using seamless technique, ensuring a smooth internal surface and uniform cross-sectional dimensions.
The ASTM A209 tubes can be used for the following purposes:
The tubes can be packaged in oil-dipped or black painted surface, packed in seaworthy bags, and hexagonal bundled to ensure that they reach the destination in perfect condition.
The seamless tube has an outer diameter ranging from 6.35mm to 101.60mm. It conforms to the standards of ASTM a209 and ASME Sa209 and has equivalent standards of EN 10216-2, ASTM A335, GOST 550-75. The material used is T1 and K11547, which has an equivalent material of P2, 12ChM, and 12CrMo. The tube is of the seamless type and is specialized for use in large diameter size. The outer dimensions range from 6-2500mm, with a wall thickness of 1-200mm. The wall thickness schedule ranges from 3mm to 15mm. The length of the tube can be up to 12m. The tube is available in schedules of STD, SCH40, and SCH80. The tube is available in forms of round, square, rectangular, hydraulic, etc. It is available in single random, double random, and cut length. The tubing end may be plain end, beveled end, or threaded.
The chemical composition of the tube is as follows:
| C, % | Mn, % | P, % | S, % | Si, % | Cr, % | Mo, % |

ASTM A209 tubing is a type of seamless tubing made from carbon-molybdenum alloy steel. This tubing is commonly used in boilers, boiler flues, and superheaters due to its high heat-resisting properties.
The carbon-molybdenum alloy steel used in the production of ASTM A209 tubing makes it highly resistant to heat and corrosion. This tubing is manufactured to strict ASTM standards, ensuring that it meets all necessary quality and safety requirements.
Boilers, boiler flues, and superheaters require tubing that can withstand high temperatures, pressures, and corrosive environments. ASTM A209 tubing is designed to perform under these rigorous conditions, making it a popular choice for these applications.
If you are in need of tubing for use in boilers, boiler flues, or superheaters, ASTM A209 tubing may be the right choice for you. Its high heat-resisting properties and strict quality standards make it a reliable and durable option for these demanding applications.
