flänstyper

Flänstyper refers to the various designs and configurations of flanges used in piping systems and mechanical assemblies. Flanges are essentially flat rim, collar, or rib on an object like a wheel, axle or shaft, used to provide strength, an attachment point, or a means of attaching the object to another object. In piping, flanges are commonly used to connect pipes to other pipes, or to valves, pumps, and other equipment, creating a leak-proof seal.

There are numerous flänstyper, each suited for specific applications and pressure ratings. Common types include weld neck flanges, which are designed for high-pressure and high-temperature service due to their tapered hub that allows for stress distribution. Socket weld flanges are used for smaller diameter, higher pressure piping and are joined by welding in a socket. Slip-on flanges are more economical and are welded both inside and outside. Lap joint flanges consist of a stub end and a backing flange, offering flexibility in alignment. Blind flanges are solid discs used to close off the end of a pipe, vessel, or opening. Threaded flanges are screwed onto a pipe thread.

The selection of the appropriate flänstyp depends on factors such as the operating pressure and temperature, the type of fluid being conveyed, and the required structural integrity of the connection. Standards organizations like ASME (American Society of Mechanical Engineers) and DIN (Deutsches Institut für Normung) define specifications for flange dimensions, materials, and pressure ratings, ensuring interchangeability and safety across different manufacturers and applications. Understanding these different flänstyper is crucial for engineers and technicians involved in the design, installation, and maintenance of piping systems.
