ASTM A358 TP 309 STAINLESS STEEL EFW PIPE-min

ASTM A358 TP 309 is a specific standard established by ASTM International for electric fusion welded (EFW) pipes made from stainless steel grade 309. The “TP” in the designation stands for “Type” and “P” indicates that the material is intended for pressure service. Here are some detailed characteristics and information about ASTM A358 TP 309 stainless steel EFW pipes:

  1. Composition: Stainless steel grade 309 is an austenitic chromium-nickel stainless steel. It contains a high amount of chromium (around 23-24%) and nickel (approximately 12-15%), which provide excellent corrosion resistance and high-temperature strength. It also contains a small amount of manganese, silicon, and carbon.

  2. Application: ASTM A358 TP 309 EFW pipes are primarily used in high-temperature environments where resistance to oxidation and scaling is crucial. These pipes find applications in various industries such as petrochemical, chemical processing, furnace manufacturing, heat treating, power generation, and other high-temperature processing equipment.

  3. Manufacturing Process: The pipes are manufactured using the electric fusion welding method. This process involves heating the edges of the stainless steel plates or strips to their melting point and then welding them together under pressure. This results in a strong and seamless weld, ensuring the integrity and reliability of the pipes.

  4. Features: ASTM A358 TP 309 stainless steel EFW pipes offer several notable features. They exhibit excellent heat resistance and can withstand high temperatures up to 1900°F (1038°C) without significant deformation or loss of mechanical properties. These pipes also provide good resistance to oxidation, carburization, and sulfidation in high-temperature environments. Additionally, they offer good weldability and formability, allowing for easy fabrication and installation.

  5. Corrosion Resistance: Stainless steel grade 309 has good resistance to corrosion in various corrosive environments, including oxidizing and reducing environments. It performs well in moderately corrosive atmospheres, such as sulfur-bearing gases encountered in petrochemical applications. However, it may not be as corrosion-resistant as some other stainless steel grades, such as 316 or 304.

It’s important to note that specific technical details, dimensions, and mechanical properties may vary based on the specific requirements of each ASTM A358 TP 309 stainless steel EFW pipe. Consulting the relevant ASTM A358 standard or contacting the manufacturer or supplier can provide more detailed and precise information for your specific application or project.
