ASTM A815 S32750 2507 Super Duplex Stainless Steel Equal Tee
Product Introduction

2507 Super Duplex Equal Tees for High-Corrosion Piping Systems

ASTM A815 UNS S32750 Equal Tee is a 2507 super duplex stainless steel butt-welding fitting designed to create a 90-degree branch connection in process piping systems.

UNS S32750 combines a ferritic-austenitic duplex microstructure with relatively high chromium, molybdenum and nitrogen contents. The grade is commonly selected for piping exposed to chloride-containing fluids, seawater, brine and demanding chemical environments.

The equal tee maintains the same nominal branch size as the run, allowing a straight pipeline to be divided into two branches of identical nominal diameter. Butt-weld ends provide a direct welded connection with the adjoining pipe.

ASTM A815 covers wrought ferritic/austenitic stainless steel fittings, while dimensional requirements for butt-welding fittings are normally specified together with applicable dimensional standards and project requirements.

Product Features
  • Super Duplex 2507 Metallurgy: UNS S32750 belongs to the super duplex stainless steel family, combining ferritic and austenitic phases to provide a balance of strength and corrosion resistance.
  • Chloride Service Capability: The high-alloy chemistry makes 2507 suitable for environments where pitting corrosion, crevice corrosion and chloride-induced stress corrosion cracking are design considerations.
  • Equal Branch Geometry: The run and branch have the same nominal diameter, making the fitting suitable for equal-size branch connections.
  • Butt-Weld Configuration: The butt-weld ends allow the tee to be directly welded to the piping system and provide a continuous flow path after fabrication.
  • Solution-Annealed Condition: Proper solution annealing is important for maintaining the intended duplex microstructure and corrosion performance.
Typical Applications
  • Seawater Piping Systems
