Laureat du prix da Vinci 2018: CHARACTERISTICS OF HIGH-PRESSURE SEALING MATERIALS FOR HYDROGEN APPLICATIONS

摘要

For the design of a technical system, the first step usually is to have a look at the current market situation and already available knowledge in the field of interest. Nowadays, a wide variety of sealing types are being used. They can be divided into two main categories, being static seals and dynamic seals [2]. Some professionals even consider permanent connections, like welds or soldered connections, as seals. Even though, this classification can be discussed, this type of connections rather plays a minor role in the context of sealing applications. More important are non-permanent type seals. These mainly include the usage of sealing compound, diaphragm seals and gaskets for static applications and radial shaft seals, rod seals, end-face seals and stuffing box seals for dynamic applications.
