Fundamentals of the design of welding sealing structures of transmission oil pipelines. Welded connectors and T-bends

Abstract

Investigations were carried out to determine the stress state of a cylindrical, connector, connectors with unloading rings, used for restoring the load-carrying capacity of sections of transmission oil pipelines with metal losses of different origins, and also a sheltering branch pipe, a branch pipe with a circular strap and a split T-bent, used as repair jackets preventing the unsealing of non-working technological fittings.

Keywords:

• trunk pipelines
