Company development

From the patented quick-release clamping ring to a system provider of pipe connections and fittings for process technology

With a patented quick-release clamping ring, LINNEMANN-Systemtechnik was established in 1980 as a special supplier of high-vacuum, technical flange connections.

LINNEMANN GmbH was founded a year later in 1981, and is an independent, family-run company. Since 2004, it has been managed by the second generation of the family, Annette, Martin and Thomas Linnemann. The company’s activity includes the development, production and sale of high-quality pipe connection systems, fittings and custom-made stainless-steel parts for plant and apparatus construction for processing gases, liquids and bulk solids.
