ASME B16.9 ASTM A234 WP5-S CL1 / CL3 Ecc. Reducer Alloy Steel Pipe Fittings
A buttweld reducer is a type of pipe fitting used to connect two pipes of different diameters. Unlike other types of reducers (e.g., socket weld or threaded reducers), buttweld reducers are designed to be welded directly to the pipes, providing a seamless connection. This makes them ideal for high-pressure and high-temperature applications. Buttweld reducers are typically made from materials like carbon steel, stainless steel, alloy steel, and sometimes even non-ferrous materials like brass or bronze. The choice of material depends on the application, including factors like temperature, pressure, and corrosion resistance.
