ASTM A335 P22 Pipe

Buy ASTM A335 Gr P22 Pipe, ASME SA335 Gr P22 Seamless SCH 40 Pipe, ASTM A335 P22 Pipe Supplier, Chrome Moly Alloy Steel Pipe, Seamless Alloy Steel Pipe for High-Temperature Applications

ASTM A335 P22 pipes are a high-strength, seamless ferritic alloy steel used predominantly in high-temperature applications across power generation, petrochemical, and gas processing industries. With a chromium content of 1.9-2.6% and molybdenum levels between 0.87-1.13%, these pipes offer exceptional corrosion resistance and mechanical stability under extreme thermal conditions, making them highly reliable in demanding environments. The material composition, enriched with chromium and molybdenum, enhances hardness, elasticity, and creep resistance, ensuring that P22 pipes perform effectively under stress and high-temperature environments up to 750°C.

These pipes are available in sizes ranging from ½” to 36” with wall thicknesses from SCH 40 to SCH XXS, allowing for flexibility in various industrial uses. ASTM A335 P22 pipes exhibit a minimum tensile strength of 415 MPa and yield strength of 205 MPa, along with an elongation rate that ensures durability during bending, forming, and welding processes. The pipes undergo strict quality control, including tests for tensile strength, hardness, and impact resistance, to ensure they meet the high standards required in thermal processing and pressure-intensive applications.

Beyond seamless pipes, the P22 grade is also manufactured in various forms, such as welded, ERW, and fabricated pipes, offering versatility for use in diverse environments. The pipes are commonly applied in equipment for chemical processing, offshore drilling, heat exchangers, and condensers, and are compatible with other high-temperature steel grades. P22 pipes are available in different lengths (double random, single random, and custom cut), and end finishes, such as plain, beveled, or threaded, to suit specific project needs.

ASTM A335 P22 pipes are frequently used in piping systems where durability and longevity are key. These pipes are finished with anti-corrosive coatings like varnish or 3PE, and they are delivered with caps on both ends to protect against moisture and debris during transport. Packaging options vary based on customer requirements, ensuring secure transit. Furthermore, pipes can be provided with certification under ASTM A335/ASME SA335 standards and inspection documentation, including EN 10204 3.1, PMI, and mechanical reports for full traceability and assurance of quality.

Welding and Heat Treatment for ASTM A335 P22 Pipes

For welding ASTM A335 P22 pipes, preheating to 120°C is often recommended, especially for thicker pipes, to prevent hardness and residual stress issues. Post-Weld Heat Treatment (PWHT) at approximately 675°C is generally suggested to maintain mechanical integrity, particularly in thicker sections. This treatment minimizes stress and enhances the durability of connections in high-temperature applications.
