Eccentric reducers are butt weld pipe fittings designed to connect pipes of different diameters while maintaining a flat side for proper alignment in horizontal piping systems. Jinhang Pipeline supplies eccentric reducers in carbon steel, low-temperature carbon steel, alloy steel, stainless steel, and duplex stainless steel for industrial piping applications.
Manufactured to applicable standards such as ASME B16.9, eccentric reducers are available in various sizes, wall thicknesses, and material grades to meet project requirements. Custom specifications are available based on customer drawings and technical requirements, supporting reliable connections in oil and gas, petrochemical, power generation, and water treatment systems.

Our eccentric reducers are manufactured in accordance with ASME B16.9 and applicable material standards, including ASTM A234/A234M for carbon and alloy steel grades. These standards help ensure dimensional compatibility and reliable performance in industrial piping systems.
We control raw material quality, forming processes, dimensions, wall thickness, and surface finish to meet specified project requirements. This helps ensure accurate fit-up, reliable connections, and consistent product quality for oil and gas, petrochemical, and other industrial applications.
Oil and Gas Industry: Connect pipes of different diameters in oil and gas transportation systems.
Petrochemical Industry: Support fluid transfer in chemical processing and refining plants.
Power Generation: Connect piping sections of different sizes in power plant systems.
Water Treatment: Facilitate pipe size transitions in water supply and treatment systems.
Industrial Piping Systems: Reduce pipe diameter while maintaining the required flat-side alignment in horizontal piping.
Chemical Processing: Support reliable flow transitions in industrial process pipelines.
