Steel butt-weld concentric reducers are designed for the smooth transition between pipes of different diameters. They are suitable for vertical piping, pump outlets, and process systems requiring axial alignment.
Fabriquées avec des équipements CNC avancés et des processus éprouvés, nos brides, cintres de tuyaux et raccords offrent des dimensions précises, des performances d'étanchéité stables et une installation fiable dans des applications industrielles exigeantes.
Normes : GB/T 12459-2025, GB/T 13401-2025 ; ASME B16.9-2024 s'applique aux projets d'exportation.
Structure/Dimensions: Concentric reducer; specify large-end and small-end diameters, wall thicknesses for both ends, and overall length; ASME B16.9 covers NPS 1/2–48 (DN15–1200), with wall thickness determined by the connected piping’s Schedule (Sch) or design thickness.
Connexion : Soudure bout à bout ; le type de biseau et les dimensions de la face de la racine doivent être confirmés sur la base des procédures de soudage et des spécifications du projet.
Material: Carbon steel, stainless steel, or alloy steel; material grade, seamless/welded type, heat treatment, and non-destructive testing (NDT) requirements must be clearly specified during the inquiry.
Pressure Rating: Butt-weld fittings typically 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/Schedule, structural dimensions, 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.
