Standards: GB\/T 12459-2025, GB\/T 13401-2025; ASME B16.9-2024 applies to export projects.
\nStructure\/Dimensions: 45\u00b0 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\u201348 (DN15\u20131200), with wall thickness specified according to the connected piping’s Schedule (Sch) or design thickness.
\nConnection: Butt-weld; bevel configuration and root face dimensions are determined based on welding procedures and project specifications.
\nMaterials: 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.
\nPressure 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.<\/p>\n
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.<\/p>","protected":false},"excerpt":{"rendered":"
