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.
Fabricados com equipamentos CNC avançados e processos comprovados, nossos flanges, curvas de tubos e acessórios oferecem dimensões precisas, desempenho de vedação estável e instalação confiável em aplicações industriais exigentes.
Padrões: GB/T 12459-2025, GB/T 13401-2025; ASME B16.9-2024 aplica-se a projetos de exportação.
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.
Conexão: Solda de topo; tipo de chanfro e dimensões da face da raiz a serem confirmadas com base em procedimentos de soldagem e especificações do projeto.
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.
