Threaded Eccentric Reducer
Threaded eccentric reducers are cone-shaped pipe fittings with grooves and internal threads for pipe connection, reducing the size of the pipeline in an eccentric manner. This pipe reducer achieves mechanical coupling by using a set of grooves at the ends of the pipes and fittings. Typically, a specialized tool is used to cut a groove at one end of the pipe, and then the joint is clamped onto the groove using bolts or a similar mechanism. The other end is threaded.
Features
Typically made of 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 eccentric 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.
