Standards: GB\/T 12459-2025, GB\/T 13401-2025; ASME B16.9-2024 applies to export projects.
\nConfiguration\/Dimensions: Stainless steel 180\u00b0 long-radius or short-radius return bend; specify center-to-center distance, end dimensions, and wall thickness; ASME B16.9 covers NPS 1\/2\u201348 (DN15\u20131200), with wall thickness specified according to the connected piping Schedule (Sch) or design thickness.
\nConnection: Butt-weld; bevel type and root face dimensions to be confirmed based on welding procedures and project specifications.
\nMaterials: Stainless steel such as ASTM A403 WP304\/304L, WP316\/316L, etc.; material grade, seamless\/welded construction, heat treatment, and NDT requirements must be clearly specified at the time of inquiry.
\nPressure Rating: Butt-weld fittings generally do not carry a specific “Class” rating; pressure-bearing capacity is determined by material, wall thickness, temperature, and applicable piping design codes.<\/p>\n
Ordering\/Acceptance: Confirm NPS\/DN, port diameters, wall thickness\/Schedule, dimensional configuration, seamless\/welded construction, 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":"
