Seamless steel 90-degree butt-weld elbows are used for right-angle turns in process piping, maintaining a continuous flow path and ensuring reliable welded connections. They are commonly used in the petroleum, chemical, power generation, and district heating industries, as well as in 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.
Configuration/Dimensions: 90° long radius (standard) or short radius; specify bending radius, center-to-end dimension, and wall thickness; ASME B16.9 covers NPS 1/2–48 (DN15–1200), with wall thickness determined by the connected piping Schedule (Sch) or design thickness.
Connection: Butt-weld; bevel configuration and root face dimensions are to be confirmed based on welding procedures and project specifications.
Material: Aço carbono, aço inoxidável ou aço de liga; os requisitos de grau de material, tipo sem costura/soldado, tratamento térmico e END devem ser claramente especificados no momento da consulta.
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, port diameters, wall thickness/Sch, dimensional configuration, 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.
