Stainless Steel 316 Seamless Pipe Tees

A Seamless Pipe Tee is a wrought fitting used to divide or combine fluid flow, creating a 90° branch from the main line. It is a fundamental component for setting up piping networks in industrial plants. While the ASTM A193 B8M specification applies to the flange bolts, these Tees are manufactured under ASTM A403 Grade WP316 (Wrought Pipe Fittings Grade 316), which is the chemically equivalent Type 316 Stainless Steel. The seamless construction provides superior material integrity without longitudinal welds, crucial for high-pressure and high-temperature service where integrity is paramount. The Molybdenum content in this alloy provides outstanding corrosion resistance against chlorides, making these Tees essential in chemical processing and offshore environments where B8M stud bolts are used to join the components. Zeron Fasteners offers both Equal Tees (where the branch diameter equals the run diameter) and Reducing Tees (where the branch diameter is smaller).
