Stub end
Stub ends are connecting elements that ensure a reliable and hermetic connection between a pipe and a flange. They guarantee precise surface alignment, uniform distribution of applied forces, and, as a result, stable and safe operation of the connection even under significant loads. Stub ends greatly simplify the installation process, reduce mechanical stress within the pipeline system, and extend the overall service life of the structure.
