Flange seals

Flange seals

Flange seals are static seals used to prevent leakage between connected flanges in various industrial applications. They are typically manufactured from materials such as PTFE (polytetrafluoroethylene) and are used in situations where a reliable seal between flanges is crucial. There are different types of flange seals, including those with an inner or outer sealing function. These seals may have a V-shaped or helical spring, usually made of acid- and rust-resistant steel. This spring helps maintain a constant pressure on the seal, ensuring an effective seal between flanges.

The V-shaped spring in a flange seal ensures even pressure distribution across the surface of the seal, which helps prevent leakage even under different pressure and temperature conditions. This type of seal can be placed on either the inner or outer side of the flange, depending on the specific requirements of the application. The spiral-wound spring, also made of acid- and rust-resistant steel, is used in flange seals to exert constant radial pressure on the seal. This spring helps keep the seal in place and ensures a uniform seal, preventing leakage even with fluctuations in pressure and temperature.

Flange seals are widely used in industries such as chemical, petrochemical, oil and gas, as well as energy and general mechanical engineering. They are used in flange connections of pipelines, equipment and systems where a reliable seal between flanges is crucial to prevent leakage of liquids or gases. Choosing the type of flange seal depends on factors such as the pressure and temperature requirements of the application, the type of medium being sealed and other specific requirements of the system. Correctly selecting and installing flange seals is essential to ensure reliable and safe system operation.
