flänskopplingar

Flänskopplingar, commonly referred to as flange connections, are mechanical joints used to connect pipes, valves, pumps, and other equipment to form a piping system. They consist of two separate flanges, a gasket or seal, and a set of bolts and nuts. Each component plays a critical role in creating a secure and leak-proof connection.

The flanges are typically ring-shaped and are welded or threaded onto the ends of the pipes or equipment. They have a flat or raised face with a series of bolt holes that align when the two flanges are brought together. The gasket, made of various materials such as rubber, PTFE, or metal, is placed between the mating faces of the flanges. Its purpose is to fill any imperfections on the flange faces, ensuring a tight seal and preventing leakage of the fluid being transported.

Bolts and nuts are used to clamp the two flanges together. The number and size of the bolts depend on the pressure and temperature requirements of the system. Tightening the bolts compresses the gasket, creating the seal. Flange connections are a common choice in industrial applications due to their strength, reliability, and ease of assembly and disassembly. They are widely used in industries such as oil and gas, chemical processing, water treatment, and power generation. Different types of flanges exist, including weld neck, slip-on, threaded, and blind flanges, each suited for specific applications and joining methods. The selection of the appropriate flange type and material is crucial for the integrity and safety of the piping system.
