Weld Neck Reducing Flanges have a tapered hub with a smaller bore to connect pipes of different diameters. This type offers the strength of a standard weld neck design while enabling transitions in pipe size. It's frequently used in high-pressure and high-temperature systems in industries like oil & gas, petrochemical, and thermal power plants.
Threaded Reducing Flanges are designed with internal threads that allow for connection without welding, featuring different sizes on the bore and flange face. These flanges are ideal for small-diameter piping systems where welding is impractical or not allowed. They are often used in low-pressure, non-critical services such as water supply and fire protection lines.
A reducing flange is used to connect pipes of different diameters, allowing for a smooth transition and maintaining efficient fluid flow while minimizing turbulence.
Reducing flanges are widely used in oil & gas, petrochemical, chemical processing, power generation, and water treatment industries for seamless pipe size transitions.
They eliminate the need for additional fittings, provide a secure and leak-proof connection, and help maintain optimal pressure and flow rates in industrial piping systems.
