Product Overview
The concentric reducer is a common pipe fitting in pipeline systems, used to connect two pipes of different diameters with their centerlines aligned along the same straight line.
Product Description
Detailed Description
Its shape is conical, with the difference in diameter between the small end and the large end achieved through smooth transition to reduce fluid resistance. For example, in a concentric reducer from DN150 to DN100, the inner diameter gradually tapers from 150 millimeters to 100 millimeters, ensuring uniform flow velocity change of the fluid.
