ANSI Standard Flange Suppliers in India

Metalfed Engineering is a leading supplier, exporter, and manufacturers of Industrial Pipe Flanges. A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. Using flanges adds flexibility when maintaining piping systems by allowing for easier disassembly and improved access to system components. A typical flanged connection is comprised of three parts i.e. Pipe Flanges, Gasket, and Bolting. In most cases, there are specific gasket and bolting materials made from the same, or approved materials as the piping components you wish to connect. Stainless Steel flanges are some of the most common. However, flanges are available in a wide range of materials so matching them with your needs is essential. Other common flange materials include Monel, Inconel, Chrome Moly, and many others depending on the application.

Common face types include: Flat Face (FF)- As the name suggests, flat face flanges feature a flat, even surface combined with a full face gasket that contacts most of the flange surface. Raised Face (RF)- These flanges feature a small raised section around the bore with an inside bore circle gasket. Ring Joint Face (RTJ)- Used in high-pressure and high-temperature processes, this face type features a groove in which a metal gasket sits to maintain the seal. Tongue and Groove (T&G)- These flanges feature matching grooves and raised sections. This aids in installation as the design helps the flanges to self-align and provides a reservoir for gasket adhesive. Male & Female (M&F)- Similar to tongue and groove flanges, these flanges use a matching pair of grooves and raised sections to secure the gasket. However, unlike tongue and groove flanges, these retain the gasket on the female face, providing more accurate placement and increased gasket material options.
