Fundamentals of design of welded sealing structures of transmission pipelines: welded couplings and T-branches

Abstract

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.
