ADCO Forge and Fittings offer Buttweld Reducers in various materials, including copper and stainless steel. These materials are chosen based on their corrosion resistance, strength, and compatibility with the fluids that will be flowing through the piping system. The company also offers custom-made reducers to meet specific customer requirements.
Concentric Reducer is a type of reducer that is used to connect pipes of different sizes in a straight line. The reduction in diameter is achieved uniformly from one end of the fitting to the other end, which results in a reduction in the flow rate. This type of reducer is commonly used in vertical piping systems, where the reduction in diameter needs to be gradual to avoid any turbulence in the flow.
On the other hand, Eccentric Reducer is a type of reducer that is used to connect pipes of different sizes that are not in a straight line. The reduction in diameter is achieved in a way that the centerline of the two pipes is not aligned. This type of reducer is commonly used in horizontal piping systems, where the reduction in diameter needs to be sudden to avoid any accumulation of fluids in the pipe.
The dimensions of ASME B16.9 Buttweld Reducers vary depending on the pipe sizes and the type of reducer. The dimensions are usually expressed in terms of the pipe diameter, wall thickness, and the length of the fitting. The dimensions of the reducer need to be accurately calculated to ensure a proper fit and to maintain the flow rate in the piping system.
