Handa’s ASTM A358 Steel Pipes are premium-grade electric-fusion-welded austenitic stainless steel pipes designed to perform reliably under high-temperature and corrosive conditions. These pipes are commonly utilized in chemical processing, petroleum refining, and other industrial sectors where durability and integrity under pressure are essential.
ASTM A358 specifies various chromium-nickel stainless steel grades such as TP304, TP304L, TP316, and TP316L, all selected for their superior corrosion resistance and heat tolerance. The manufacturing process involves electric-fusion welding, ensuring high-quality welds with excellent mechanical properties and structural integrity.
The standard defines five class designations (Class 1 to Class 5), each with distinct welding and heat treatment requirements. Radiographic or ultrasonic testing is applied to certain classes to ensure weld soundness. Pipes can be supplied in different surface finishes including annealed pickled, bright annealed, or polished, and are available with plain, beveled, or threaded end connections.
These pipes offer high temperature strength, outstanding corrosion resistance, and excellent weld quality—making them well-suited for condensers, heat exchangers, reactors, and other components in demanding environments.
