Considered are the technical capabilities of simplified manufacture of all-metal high-pressure vessels for delivery of natural gas through application of prefabricated 351–610 mm pipes from higher strength steels. Dimension-weight parameters and stresses in the vessel wall, depending on steel strength, are determined. The structure, structural-mechanical inhomogeneity and fatigue resistance of the welded joints were examined. Elimination of rolling, welding, thermomechanical treatment, heat treatment of the shell from the technological process and formation of outer fiberglass casing, as well as reduction of wall thickness, diameter and weight provides significant simplification of vessel manufacture, reduction of the number of passes, time of welding the circumferential welds, and power consumption. 25 Ref., 1 Table, 5 Figures.
Keywords: all-metal high-pressure vessels, pipes, stresses, welded joints, structure, mechanical properties, cyclic fatigue life, dimension-weight characteristics
