What is a Butt Weld Reducing Tee?
A butt weld reducing tee is a type of pipe fitting used to combine or split fluid flow in pipelines while transitioning between different pipe diameters. Its unique design features one outlet with a smaller diameter (reducing branch) and two run ends of larger sizes, enabling smooth flow redirection and pressure management. These fittings are critical in applications requiring precise dimensional adjustments, such as oil and gas, chemical processing, power generation, and shipbuilding.
