This product display features three types of steel butt-weld pipe fittings: 90° seamless elbows for changing direction, reducing tees for branching and size transitions in main lines, and concentric reducers for coaxial pipe diameter transitions. All three are suitable for welded pressure piping systems.
Unsere Flansche, Rohrbögen und Armaturen werden mit fortschrittlicher CNC-Ausrüstung und bewährten Prozessen hergestellt und liefern genaue Abmessungen, stabile Dichtungsleistung und zuverlässige Installation für anspruchsvolle industrielle Anwendungen.
Standards: GB/T 12459-2025, GB/T 13401-2025; ASME B16.9-2024 gilt für Exportprojekte.
Structure/Dimensions: Composite products; specify elbow radius, tee run × branch sizes, and reducer large-end × small-end sizes with respective wall thicknesses; ASME B16.9 covers NPS 1/2–48 (DN15–1200), with wall thickness specified according to the connected piping Schedule (Sch) or design thickness.
Connection: Butt-weld; bevel type and root face dimensions are determined by welding procedures and project specifications.
Materials: Carbon steel, stainless steel, or alloy steel; material grade, seamless/welded type, heat treatment, and NDT requirements must be clearly specified during inquiry.
Druckbewertung: Stumpfschweißanschlüsse tragen im Allgemeinen keine eigenständige Bewertung “Klasse”; Die Drucktragfähigkeit wird durch Material, Wandstärke, Temperatur und geltende Rohrleitungsdesigncodes bestimmt.
Ordering/Acceptance: Confirm NPS/DN, port sizes, wall thickness/Sch, 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.
