These stainless steel butt-weld reducers feature aligned centerlines at both ends and are designed for coaxial diameter transitions in pipelines conveying corrosive or high-purity media. They minimize local flow resistance caused by abrupt changes in cross-section, making them suitable for vertical piping and pump discharge applications.
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; export projects may comply with ASME B16.9-2024.
Structure/Dimensions: Stainless steel concentric reducer; specify large-end × small-end diameters, wall thicknesses for both ends, and length; ASME B16.9 covers NPS 1/2–48 (DN15–1200), with wall thickness specified according to the connected piping Schedule (Sch) or design thickness.
Connection: Butt-weld; bevel type and root face dimensions to be confirmed based on welding procedures and project specifications.
Material: Stainless steel such as ASTM A403 WP304/304L, WP316/316L, etc.; manufacturing grade to be confirmed via the quality certificate; 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, structural dimensions, seamless/welded type, material grade, heat treatment, bevel details, and NDT requirements; verify pressure-bearing capacity based on material, wall thickness, temperature, and piping design codes.
