ASTM A209 Grade T1 is a specification that covers minimum-wall-thickness, seamless, carbon-molybdenum alloy-steel, boiler and superheater tubes. The tubes are used in various industries such as petrochemical, chemical, and power generation industries, and are known for their excellent heat-resistant properties.
As per the ASTM A209 standard specification, these tubes are made of carbon-molybdenum alloy steel and are seamless in nature. The tubes come in a variety of sizes, with an outer diameter ranging between 10mm and 203mm, and a wall thickness ranging between 2.0mm and 25mm. Additionally, they can come in lengths of 5.8-12m, depending on the specific application and customer requirements.
The ASTM A209 standard specifies the requirements for seamless carbon-molybdenum alloy-steel tubes, suitable for use in boiler and superheater applications.
These tubes are available in a range of outer diameters, from 10mm to 203mm, with wall thicknesses ranging from 2.0mm to 25mm. The length of the tubes can be provided in accordance with customer needs, between 5.8-12m.
The ASTM A209 standard identifies three grades for these tubes: ASTM A209 T1, ASTM A209 T1a, and ASTM A209 T1b.
These tubes are produced using the seamless technique.
