Flange connections are mechanical joints used to connect pipes, valves, pumps, and other equipment in barrel assemblies, providing a secure, leak-proof seal.
A flange connection is a type of mechanical joint that uses flanges—flat, circular discs with bolt holes—to connect sections of pipes, valves, or other components in industrial systems, such as barrel assemblies. It typically involves two flanges aligned and bolted together with a gasket inserted between them to create a pressure-tight seal. These connections are designed to withstand operational stresses, including pressure, temperature, and vibration, and are commonly used in applications requiring easy assembly, disassembly, and maintenance.

Common types include weld neck, slip-on, threaded, socket weld, and blind flanges, each suited for different pressure and assembly needs.
Prevent leaks by using the correct gasket material, applying proper bolt torque in a star pattern, and ensuring flange faces are clean and aligned.
Key standards include ISO 7005 for dimensions, ASME B16.5 for pressure ratings, and DIN 2501 for design specifications.
