A concentric reducer is a type of pipe reducer that connects two pipes of different diameters. The fitting’s name derives from the fact that it is welded to the pipe, resulting in a strong and secure connection. There are many benefits to using buttweld fittings, such as their increased durability and leak-resistant nature. Additionally, they can be used in a wide variety of applications, making them a versatile option for both home and industrial use. The advantages of Buttweld Fittings include: -Welding a fitting to the pipe means it is permanently leak proof; -The continuous metal structure formed between pipe and fitting adds strength to the system; -Smoother inner surface and gradual direction changes reduce the pressure losses and turbulence and minimises the action of corrosion and abrasion; -A welded system utilises minimal space;
