vinkelböjt

Vinkelböjt is a Swedish term used to describe an elbow-shaped component that introduces a change in direction in a line of material such as a tube, pipe, rod, or flat bar. The word combines vinkel (angle) and böjt (bent) and is employed across engineering, plumbing, metalworking, and construction to refer to pieces that form an angle between two connected segments. In practice, its meaning depends on context, but it generally denotes a bend or elbow element.

Common forms of vinkelböjt include right-angle elbows and other specified angles, with 90 degrees and 45 degrees being the most typical. The term can apply to fittings in piping and drainage systems as well as to bent structural or reinforcing elements in metalwork and construction. The size and bend radius vary, with short-radius versions producing tighter bends and long-radius versions reducing stress concentrations.

Materials used for vinkelböjt range from metals—such as galvanized steel, stainless steel, copper, and aluminum—to plastics like PVC, depending on the application, corrosion resistance requirements, and load conditions. Production methods include bending, forging, or casting, sometimes followed by welding or machining to achieve precise tolerances.

Applications span plumbing, heating and cooling (HVAC), drainage, and various forms of structural framing or reinforcement in concrete work. In technical catalogs or specifications, vinkelböjt is often listed with the exact angle, diameter or cross-sectional size, and the chosen material, along with any applicable standards or code requirements for the intended system.
