Eccentric butt-weld reducers allow one side of the pipe wall to remain flush, thereby minimizing gas accumulation at pump suction inlets or liquid pooling in horizontal pipelines. During installation, the orientation—whether “flat-on-top” or “flat-on-bottom”—must be clearly specified.
Manufactured with advanced CNC equipment and proven processes, our flanges, pipe bends, and fittings deliver accurate dimensions, stable sealing performance, and dependable installation across demanding industrial applications.
Standards: GB/T 12459-2025, GB/T 13401-2025; ASME B16.9-2024 applies to export projects.
Configuration/Dimensions: Eccentric reducer; specify large-end and small-end diameters, wall thicknesses for both ends, length, and flat-side orientation (flat-top or flat-bottom); ASME B16.9 covers NPS 1/2–48 (DN15–1200), with wall thickness determined by the connected piping’s Schedule (Sch) or design thickness.
Connection: Butt-weld; bevel type and root face dimensions are to be confirmed based on the welding procedure and project specifications.
Material: Carbon steel, stainless steel, or alloy steel; material grade, seamless/welded type, heat treatment, and NDT requirements must be clearly specified at the time of inquiry.
Pressure Rating: Butt-weld fittings generally do not carry a standalone “Class” rating; pressure-bearing capacity is determined by material, wall thickness, temperature, and applicable piping design codes.
Ordering/Acceptance: Confirm NPS/DN, end diameters, wall thickness/Sch, dimensional configuration, seamless/welded type, material grade, heat treatment, bevel details, and NDT requirements; pressure-bearing capacity is verified based on material, wall thickness, temperature, and piping design codes.
