Buttweld Reducer

A butt-welded reducer is a type of pipe fitting used in piping systems to connect two pipes of different diameters. It allows for a smooth transition between pipes of varying sizes while maintaining the flow characteristics of the system. Butt-welded reducers are welded to the pipes end-to-end, ensuring a strong, leak-proof, and durable joint, especially in high-pressure and high-temperature environments.

There are two main types of butt-welded reducers:
1. Concentric Reducer: This type has a cone-shaped design and the centerline of both ends remains aligned. It is used when there is a need to maintain the same centerline in horizontal pipelines. Concentric reducers are commonly used in vertical piping and pump discharge applications.
2. Eccentric Reducer: In this type, the centerline of the ends is offset. It is typically used in horizontal pipe runs to prevent air accumulation (top flat) or avoid cavitation, especially in pump suction lines.
Butt-welded reducers are made from materials like carbon steel, stainless steel, or alloy steel, and conform to industry standards such as ASME B16.9. They are essential in systems requiring changes in pipe diameter while ensuring minimal turbulence and pressure loss.
