flänsanslutning

A flänsanslutning, commonly referred to as a flange connection in English, is a method used to join pipes, valves, pumps, and other equipment to form a piping system. This connection is achieved by bolting together two flanged ends. A gasket is typically placed between the flanged faces to create a seal and prevent leakage.

Flange connections are widely used in industrial applications due to their strength, reliability, and ease of disassembly. They are particularly suitable for high-pressure and high-temperature environments where other joining methods might fail. The design of a flange connection involves several key components: the flanges themselves, bolts, nuts, and a gasket.

Flanges come in various types, including weld neck, slip-on, threaded, socket weld, and lap joint, each suited for different applications. The choice of flange type depends on factors such as pressure, temperature, fluid type, and installation requirements. The bolting pattern and torque applied to the bolts are critical for ensuring a leak-free and secure connection. Proper alignment of the flanges and correct installation of the gasket are essential to prevent premature failure.

Disassembly of a flanged joint is relatively straightforward, allowing for easy maintenance, repair, or replacement of components within the piping system. This reusability makes flange connections a practical choice for many industrial settings.
