This article describes the determination of the stress state of cylindrical couplings, couplings with unloading rings used for restoring the load-carrying capacity of sections of transmission pipelines with metal losses of different origin, and also of sheltering branch pipes, branch pipes with a ring-shape strap and a split T-branch, used as repair jackets preventing unsealing of fittings. © 2012 Copyright Taylor and Francis Group, LLC.
