ASME B16.11 Threaded Screwed Unequal Tee Manufacturer

What is a Threaded Screwed Unequal Tee?

ASME B16.11 Threaded Screwed Unequal Tee is a forged pipe fitting designed to create a 90° branch connection where the branch outlet is of a smaller size than the main pipe. Its threaded ends allow for quick assembly without welding, making it ideal for systems where heat-based joining is not preferred. This design ensures a secure, pressure-tight connection in low to medium-pressure piping applications.

These unequal tees are widely used to regulate flow direction and distribute fluids efficiently across varying pipe diameters. The reduced branch size helps control flow rate and pressure, making them suitable for systems handling air, water, oil, gas, and various process fluids. Their robust construction ensures durability even in demanding industrial environments.

Manufactured according to ASME B16.11 standards, these fittings offer consistency in dimensions, quality, and performance. They are commonly produced from materials like stainless steel, carbon steel, and alloy steel to match the needs of different applications. Their ease of installation and excellent mechanical strength make Threaded Screwed Unequal Tees a reliable choice for refineries, petrochemical plants, power stations, and general industrial piping networks.
