6IN SCH80 ASTM A234 WPB Concentric Reducer
A concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1″ pipe transitions into a 3/4″ pipe and the top or bottom of the pipe doesn’t need to remain level.
6IN SCH80 ASTM A234 WPB Concentric Reducer allows for a change in pipe size to meet hydraulic flow requirements of the system, or to adapt to existing piping of a different size.A concentric reducer, which is also known as a tapered expansion joint, is a fitting used to connect two pipes or tubes that have different inside diameters. Both tubes need to share a common centerline or alignment in order to facilitate the flow of fluid or a substance. Reducers can be manufactured using rubber, stainless steel, carbon steel, steel alloy, titanium alloy, copper, nickel, cast iron, brass, or other materials that have met the standards of the pipe industry. It is normally used in joining vertical pipes that need to be anchored for safety reasons. Concentric reducers are common in both the onshore and offshore operation of the oil and gas industry where there is a heavy volume of cargo transfer and vapor recovery.

The two ends of a concentric reducer have unequal diameters in order to achieve its purpose of joining two pipes with different diameters. Its smaller end joins with the smaller pipe while the end with the larger diameter joins with the larger pipe. The ends of a concentric reducer are put together by a cone-shaped transition section to form a single assembly. Joining of the two ends of a concentric reducer can either be done through seamless integration or through welding.
