Concentric & Eccentric Reducers are essential butt welded pipe fittings designed to connect pipes of different diameters while maintaining stable flow, pressure balance, and structural integrity within piping systems. These reducers play a critical role in fluid transportation, pressure control, and system optimization across a wide range of industrial applications.
SSTU is a professional manufacturer and exporter specializing in high-performance concentric reducers and eccentric reducers , supplying reliable piping solutions for oil & gas, chemical processing, power generation, marine engineering, and water treatment industries worldwide.
Concentric Reducers feature a common centerline, allowing smooth and symmetrical flow transition between different pipe sizes. They are typically used in vertical piping systems or applications where uniform flow distribution is required.
Eccentric Reducers are designed with an offset centerline, enabling flat-top or flat-bottom installation. This design helps prevent air accumulation or liquid pooling, making eccentric reducers ideal for horizontal pipelines, pump suction lines, and applications where drainage and cavitation prevention are critical.
SSTU Concentric & Eccentric Reducers are manufactured from premium raw materials to meet various corrosion resistance and mechanical strength requirements. Available material options include:
Carbon steel, stainless steel, low alloy steel, duplex stainless steel, super duplex stainless steel, nickel alloy steel, and other special alloys. For highly corrosive or high-strength environments, our reducers are commonly used together with Duplex Steel Seamless Pipe to ensure consistent system performance and extended service life.
All concentric and eccentric reducers are produced in strict accordance with international standards including ASTM, ASME, ANSI, DIN, EN, JIS, and GB. Commonly applied standards include ASTM A234, ASTM A403, ASTM A815, ASME B16.9, and ASME B16.28.
Our reducers are available in a wide range of nominal pipe sizes (NPS), schedules, and wall thicknesses. Custom dimensions, special tolerances, and project-specific requirements can be provided upon request to support complex pipeline engineering projects.
SSTU concentric and eccentric reducers are manufactured using advanced forming processes such as hot pressing, cold forming, extrusion molding, welding, and precision heat treatment. Each reducer is carefully engineered to ensure uniform wall thickness, accurate dimensions, and excellent weldability.
Our comprehensive quality control system includes chemical composition analysis, mechanical property testing, dimensional inspection, and non-destructive testing. Detailed procedures and certifications can be reviewed on our Quality Control page.
