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.
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: 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.
Connection: Butt-weld; bevel configuration and root face dimensions are determined based on welding procedures and project specifications.
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.
Indice de pression : les raccords soudés bout à bout ne se voient généralement pas attribuer une cote de“ spécifique de classe ” ; la capacité portante est déterminée par une combinaison de matériaux, d'épaisseur de paroi, de température et de codes de conception de tuyauterie applicables.
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.
