Concentric Reducer is a pipe fitting used to connect pipes of different diameters, characterized by having centerlines of both ends on the same line, forming a concentric structure. The product is widely used in various pipeline systems to achieve smooth transition connections between different pipe diameters, ensuring continuous flow of fluid in the pipeline. Concentric reducers play an important role in pipeline systems in industries such as petrochemical, power, HVAC, and water supply and drainage, especially in situations requiring changes in pipe diameter without changing the pipe centerline position. The concentric structure design results in relatively low fluid resistance and low pressure loss, suitable for operating conditions with strict pressure loss requirements. The product is manufactured using high-quality carbon steel, stainless steel or alloy steel materials, undergoes precision machining to ensure dimensional accuracy and surface quality.
