- Abstract
Application of two-layer shells for formation of common wall is supposed to be prospective for reduction of weight of pipeline structures as well as pressure vessels. Calculation of three single-type pressure vessel structures, having common wall, which is made as two-layer shell, was carried out. At that, analysis was given for applied materials and their combination used for manufacture of internal and external shells of common two-layer wall of three types of pressure vessels considering their strength indices. It is determined that application of the same steel grade in two-layer structure does not result in efficient loading of common wall. Application of material with higher strength characteristics for manufacture of external shell results in efficient loading of their common wall, reduction of its thickness and growth of its internal stresses, i.e. reasonable loading. Considered are the issues of application of mesh-like material for manufacture of external shell as well as usage of high-frequency pressure braze-welding in production of perspective tubular billets, designed for pipelines and high-pressure vessels.
