We are committed to providing one-stop service for steel pipe products to customers around the world.
Concentric Reducers (CR)
Concentric reducers are used to transition between pipes of the same diameter. They come in both steel and cast iron, and they can be found in a variety of sizes, including 2-inch, 3-inch, 4-inch and 6-inch. They are also known as male reducers because their outside diameter is larger than the inside diameter of their mating part (in this case a female adapter).
Eccentric Reducers (ER)
Eccentric reducers are used to transition between pipes of different diameters. The eccentric design allows for the joining of a pipe with an inside diameter that is larger than another.
