tätningslägen

Tätningslägen, which translates to "sealing positions" or "gasket seats" in English, refers to the specific surface areas or interfaces within a mechanical assembly where a sealing element, such as a gasket or O-ring, is intended to make contact to prevent leakage. These lägen are critical for the integrity of fluid or gas containment in various engineering applications, from simple plumbing to complex industrial machinery.

The design of tätningslägen is paramount for effective sealing. They are typically machined surfaces that are designed to be smooth, flat, and free from imperfections like scratches, burrs, or corrosive damage. The geometry of the lägen, including their dimensions and tolerances, must be precise to ensure uniform compression of the sealing element. Deviations from the intended design can lead to uneven pressure distribution, creating pathways for leakage.

When an assembly is put together, the sealing element is placed between the opposing tätningslägen. As fasteners are tightened, the sealing element is compressed, deforming slightly to fill any microscopic irregularities on the surface of the lägen. This compression creates a barrier that prevents the passage of the contained medium. The material properties of both the sealing element and the lägen play a significant role in the overall sealing performance, especially under varying temperature and pressure conditions. Regular inspection and maintenance of these sealing surfaces are essential to maintain system reliability and prevent costly failures.
