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.
Fabriquées avec des équipements CNC avancés et des processus éprouvés, nos brides, cintres de tuyaux et raccords offrent des dimensions précises, des performances d'étanchéité stables et une installation fiable dans des applications industrielles exigeantes.
Normes : GB/T 12459-2025, GB/T 13401-2025 ; ASME B16.9-2024 s'applique aux projets d'exportation.
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.
Indice de pression : les raccords soudés bout à bout n'ont généralement pas d'indice de dilution autonome de classe “ ; la capacité portante est déterminée par le matériau, l'épaisseur de la paroi, la température et les codes de conception de tuyauterie applicables.
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.
