When a stainless steel stub end is paired with a loose flange, the process medium contacts only the corrosion-resistant stub end, while the external loose flange can be made of a different material and rotated for alignment. This configuration is suitable for corrosive media and piping systems requiring frequent disassembly.
Fabricados com equipamentos CNC avançados e processos comprovados, nossos flanges, curvas de tubos e acessórios oferecem dimensões precisas, desempenho de vedação estável e instalação confiável em aplicações industriais exigentes.
Reference Standards: ASME B16.9; low-pressure, corrosion-resistant thin-wall systems may comply with MSS SP-43-2026 (Sch 5S/10S; short patterns also available in Sch 40S).
Configuration: Long-pattern or short-pattern stainless steel lap-joint stub ends; specifications must include nominal size, wall thickness, length, lap outer diameter, lap thickness, and fillet radius.
Materials: Stainless steel grades such as ASTM A403 WP304/304L, WP316/316L, etc.
Matching Components: Lap-joint flanges, gaskets, bolts, and sealing faces must be selected based on the same pressure rating system.
Pressure Rating: Determined by the stub end wall thickness, material, and the associated flange assembly.
Ordering/Acceptance: Confirm the pattern (long or short), nominal size, wall thickness, barrel length, lap dimensions, fillet radius, and material; ensure compatibility with the matching lap-joint flange, gasket, and bolting system.
