anslutningsfläns

Anslutningsfläns, often simply called a fläns, is a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It is a planar surface at the end of a pipe, fitting, valve, or other component that is used to connect it to another component. The connection is typically made by bolting two fläns together, with a gasket placed between the fläns to provide a seal.

Fläns are commonly used in industrial applications where pipes need to be joined or disconnected for maintenance, repair, or expansion. They offer a reliable and strong connection that can withstand high pressures and temperatures. The design of a fläns can vary depending on the application, but common types include weld neck fläns, slip-on fläns, threaded fläns, and lap joint fläns. Each type has specific advantages and is suited for different working conditions.

The material of a fläns is also important and depends on the substance being transported and the operating environment. Common materials include carbon steel, stainless steel, and various alloys. The dimensions and specifications of fläns are standardized by organizations like ASME (American Society of Mechanical Engineers) and DIN (Deutsches Institut für Normung) to ensure interchangeability and compatibility between different manufacturers' products. Proper selection and installation of fläns are crucial for the safety and integrity of any piping system.
