Standards: GB\/T 12459-2025, GB\/T 13401-2025; ASME B16.9-2024 applies to export projects.
\nConfiguration\/Dimensions: Eccentric reducer; specify large-end and small-end diameters, wall thicknesses for both ends, length, and flat-side orientation (flat-top or flat-bottom); 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 are to be confirmed based on the welding procedure and project specifications.
\nMaterial: Carbon steel, stainless steel, or alloy steel; material grade, seamless\/welded type, heat treatment, and NDT requirements must be clearly specified at the time of inquiry.
\nPressure Rating: Butt-weld fittings generally 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\/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.<\/p>","protected":false},"excerpt":{"rendered":"
