This tubing, conforming to the ASTM A269 standard, is designed for general service applications where corrosion resistance and mechanical strength are paramount. Here, we delve deeper into its chemical composition, mechanical properties, heat treatment status, size range, impact testing, primary applications, and a supply case study from TJC Steel Group.

Chemical Composition

A269 TP348 tubing boasts a chemical composition that ensures its robust corrosion resistance. Key alloying elements include chromium, nickel, and molybdenum, which provide the material with excellent resistance to various chemical environments. The precise chemical composition is tailored to meet the requirements of ASTM A269, ensuring consistent quality and performance.

Mechanical Properties

The mechanical properties of A269 TP348 tubing are remarkable. It exhibits high tensile strength and yield strength, allowing it to withstand significant pressure and loads. Furthermore, its ductility and toughness enable it to withstand vibration and impact without failure. These mechanical properties are verified through rigorous testing, ensuring that the tubing meets or exceeds industry standards.

Heat Treatment Status

A269 TP348 tubing undergoes a specific heat treatment process to enhance its mechanical properties and corrosion resistance. This heat treatment typically involves heating the material to a specific temperature and then cooling it rapidly. This process alters the microstructure of the steel, resulting in improved strength, ductility, and corrosion resistance.

Size Range

A269 TP348 tubing is available in a wide range of sizes to suit various applications. Common sizes include diameters ranging from 1/4 inch (6.4 mm) and larger, with nominal wall thicknesses starting at 0.020 inch (0.51 mm) and heavier. This flexibility in size range ensures that A269 TP348 tubing can be used in a diverse set of applications.

Impact Testing

To ensure the toughness and reliability of A269 TP348 tubing, it undergoes impact testing. This test involves using a pendulum-type impact tester to strike a notched specimen and measure the energy absorbed during fracture. The results of these tests provide valuable insights into the material's ability to withstand sudden impacts and dynamic loading.

Primary Applications

A269 TP348 tubing finds widespread application in industries where corrosion resistance and mechanical strength are crucial. This includes the transportation of fluids such as gas, water, and oil in chemical processing plants, oil and gas fields, and power generation facilities. Its excellent corrosion resistance and mechanical properties make it a reliable choice for these demanding applications.
