🔹 What Are ASTM A403 WP321 Tees?

ASTM A403 WP321 Tees are high-performance buttweld pipe fittings manufactured from austenitic stainless steel 321 (UNS S32100). These tees connect three pipes at 90° angles, distributing or combining flow in piping systems.

The addition of titanium stabilization makes 321 stainless steel resistant to carbide precipitation during welding, offering excellent oxidation resistance at elevated temperatures. This makes WP321 tees ideal for chemical processing, power plants, automotive exhaust systems, heat treatment, and petrochemical industries.

🔹 Types of ASTM A403 WP321 Tees

• Equal Tee (WP321): All outlets of the same size.

• Reducing Tee (WP321): Branch outlet smaller than the main run.

• Available in Seamless, Welded, and Fabricated designs, complying with ASTM A403 / ASME B16.9 standards.
