Stainless steel butt-weld pipe caps are used to seal the ends of pipelines conveying corrosive, clean, or high-purity media. When joined to the pipe via a full-penetration weld, they form a permanent pressure boundary, thereby reducing potential leak points associated with threaded or flanged connections.
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: Stainless steel butt-weld pipe cap; specify nominal size, wall thickness, total depth, and end bevel; 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 based on the welding procedure and project specifications.
Material: Stainless steel such as ASTM A403 WP304/304L, WP316/316L, etc.; material grade, seamless/welded type, heat treatment, and non-destructive testing (NDT) requirements must be clearly specified at the time of inquiry.
Druckbewertung: Stumpfschweißanschlüsse haben im Allgemeinen keine eigenständige Bewertung “Klasse”; Die Drucktragfähigkeit wird durch Material, Wandstärke, Temperatur und geltende Rohrleitungsdesigncodes bestimmt.
Ordering/Acceptance: Confirm NPS/DN, nominal size, 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.
