A 45° butt-weld elbow formed from seamless stainless steel stock, designed to smoothly change the direction of fluid flow while minimizing the risk of corrosion or leakage associated with weld seams. Suitable for applications in the chemical, pharmaceutical, food processing, and water treatment industries, as well as for high-purity 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: 45° long-radius elbows are the standard type; orders must specify center-to-end dimensions, outside diameter, and wall thickness; ASME B16.9 covers NPS 1/2–48 (DN15–1200), with wall thickness specified according to the connected piping’s Schedule (Sch) or design thickness.
Conexão: Solda de topo; a configuração do chanfro e as dimensões da face da raiz são determinadas com base nos procedimentos de soldagem e nas especificações do projeto.
Materials: Common stainless steel grades include ASTM A403 WP304/304L and WP316/316L; seamless status is verified via the material test report; inquiries must clearly specify material grade, seamless/welded construction, heat treatment, and non-destructive testing (NDT) requirements.
Pressure Rating: Butt-weld fittings are generally not assigned a specific “Class” rating; pressure-bearing capacity is determined by a combination of material, wall thickness, temperature, and applicable piping design codes.
Ordering/Acceptance: Confirm NPS/DN, port diameters, wall thickness/Schedule, structural dimensions, seamless/welded construction, material grade, heat treatment, bevel configuration, and NDT requirements; pressure-bearing capacity is verified based on material, wall thickness, temperature, and piping design codes.
