Standards: GB\/T 12459-2025, GB\/T 13401-2025; ASME B16.9-2024 applies to export projects.
\nStructure\/Dimensions: Concentric reducer; specify large-end and small-end diameters, wall thicknesses for both ends, and overall length; ASME B16.9 covers NPS 1\/2\u201348 (DN15\u20131200), with wall thickness determined by the connected piping’s Schedule (Sch) or design thickness.
\nConnection: Butt-weld; bevel type and root face dimensions to be confirmed based on welding procedures and project specifications.
\nMaterial: Carbon steel, stainless steel, or alloy steel; material grade, seamless\/welded type, heat treatment, and non-destructive testing (NDT) requirements must be clearly specified during the inquiry.
\nPressure 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.<\/p>\n
Ordering\/Acceptance: Confirm NPS\/DN, end diameters, wall thickness\/Schedule, 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.<\/p>","protected":false},"excerpt":{"rendered":"
