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.
Prodotti con apparecchiature CNC avanzate e processi collaudati, le nostre flange, curve per tubi e raccordi offrono dimensioni accurate, prestazioni di tenuta stabili e installazione affidabile in applicazioni industriali impegnative.
Norme: GB/T 12459-2025, GB/T 13401-2025; L'ASME B16.9-2024 si applica ai progetti di esportazione.
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.
Valutazione della pressione: i raccordi con saldatura di testa generalmente non hanno un rating autonomo “Class”; la capacità di carico della pressione è determinata dal materiale, dallo spessore della parete, dalla temperatura e dai codici di progettazione delle tubazioni applicabili.
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.
