    Threaded concentric reducers are cone-shaped pipe fittings that have grooves and internal threads for connection. They reduce the size of the pipeline in a symmetrical and concentric manner while keeping the centerlines of the two pipes aligned. This product achieves mechanical coupling by using a set of grooves at the ends of the pipes and fittings. Typically, one end is grooved using a specialized tool, and then the joint is clamped onto the groove using bolts or a similar mechanism. The other end is threaded.

    Features
    • Made of materials such as ductile iron, stainless steel, or carbon steel, which provide strong wear resistance and corrosion resistance.
    • Available in various sizes and pressure ratings, suitable for different applications.
    • Enables the connection of two pipes with different diameters.
    Recommended Applications

    Threaded concentric reducers are commonly used in industrial and commercial piping systems, such as gas pipelines, water supply pipelines, etc., where the size of the pipeline needs to be reduced to accommodate changes in flow or pressure.
