Backup flanges

1. Backup flanges https://www.nehametalalloys.com/backup-flanges-manufacturers-suppliers-importers-exporters- stockists.html Backup flanges are non-pressure-retaining components used in piping systems, especially in conjunction with plastic, fiberglass-reinforced plastic (FRP), or lined pipes. They are used to secure stub ends or Van Stone fittings and allow for easy assembly and disassembly of pipeline connections. Unlike traditional flanges, backup flanges do not come into contact with the process fluid; instead, they apply pressure to a sealing surface, usually formed by the stub end, to ensure a leak-proof joint. Design and Function Backup flanges are circular rings, typically with bolt holes, designed to work with lap joint or Van Stone stub ends. Their primary function is to distribute pressure and secure the connection mechanically. These flanges allow for pipe rotation during installation, facilitating bolt hole alignment. Since they do not hold pressure directly, they rely on the stub end and gasket for sealing. Types of Backup Flanges Lap Joint Backup Flange Used with a stub end; the flange moves freely for alignment. Van Stone Flange Combines a molded or machined stub with a loose metal or plastic flange. Split Flange Made in two halves, bolted together around a pipe for easy installation in confined spaces. Composite Flange Made of polymer or fiber-reinforced materials; ideal for corrosive environments. Common Materials Carbon Steel– Strong and affordable for general industrial use. Stainless Steel (304/316)– Corrosion-resistant; ideal for sanitary or marine applications. Ductile Iron– High strength; suitable for waterworks. Aluminum– Lightweight and corrosion-resistant. FRP/Plastic (PVC, CPVC, Polypropylene)– Ideal for chemical or water systems.
