flänsens

Flänsens is a term in Swedish-language technical vocabulary that is most often encountered as the genitive form of fläns, meaning the flange. In practical use, fläns denotes a circular or irregular protruding ring used to connect components such as pipes or pressure vessels. Flänsens, as the possessive form, appears in phrases describing properties or parts related to a flange, for example "flänsens hålpattern" (the flange's bolt hole pattern). However, the standalone form flänsens is uncommon in everyday technical writing, where the definite article form flänsen or the noun fläns is preferred.

A flange is a mechanical connector that provides a mating face, bolt holes, and a seating surface for gaskets. Flanges enable assembly, alignment, and disassembly of piping systems and equipment, and they are available in various types, including weld-neck, slip-on, blind, threaded, and lap-joint. Materials commonly used for flanges include carbon and stainless steels, as well as alloys such as duplex steel or high-strength alloys, chosen for pressure rating, temperature, and corrosion resistance. Standards such as ANSI/ASME B16.5 and EN 1092-1 specify flange sizes, pressure classes, and bolt patterns.

In linguistic use, flänsens is not a separate concept but a grammatical form. In other contexts, Flänsens may appear as a name or brand in fiction or marketing, but it has no widely recognized technical meaning beyond the possessive use of fläns.
