Buttweld fittings are a type of pipe fittings used in piping systems to connect, change direction, or control the flow of fluids (liquids or gases) through pipelines. These fittings are designed to be welded directly to the ends of pipes, creating a secure and leak-proof connection. The term “buttweld” refers to the method of joining the fittings to the pipes, which involves welding the ends of the fitting to the ends of the pipe using a butt-welding process.
Concentric reducers have a common centerline for both ends, while eccentric reducers have one end off-center, often used to maintain a level flow or drainage.
