This product display features three types of steel butt-weld pipe fittings: 90° seamless elbows for changing direction, reducing tees for branching and size transitions in main lines, and concentric reducers for coaxial pipe diameter transitions. All three are suitable for welded pressure piping systems.
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: Composite products; specify elbow radius, tee run × branch sizes, and reducer large-end × small-end sizes with respective wall thicknesses; 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 are determined by welding procedures and project specifications.
Materials: Carbon steel, stainless steel, or alloy steel; material grade, seamless/welded type, heat treatment, and NDT requirements must be clearly specified during inquiry.
Classificação de pressão: Os acessórios de solda de topo geralmente não possuem uma classificação autônoma de “Class”; a capacidade de suporte de pressão é determinada pelo material, espessura da parede, temperatura e códigos de projeto de tubulação aplicáveis.
Ordering/Acceptance: Confirm NPS/DN, port sizes, wall thickness/Sch, 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.
