Methodical Aspects of Standardization of All-Metal High-Pressure Spherical Tanks for Compressed and Liquefied Gases

The standardization of high-pressure spherical tanks for compressed and liquefied gases is a promising cost reduction solution in the rocket and space industry. This article proposes a methodical basis to the search for the rational values of the parametric series of the standardized spherical tanks. The optimization criterion for the parametric series values is scientifically substantiated, and the efficiency of the proposed criterion is shown. The authors determine the interrelation of the grouping points of the energy values for mass-produced spherical tanks and energy intervals for the application of the standardized products. It is shown that using the proposed approach, it is possible to reduce the nomenclature of the spherical tanks by half. The area of energy of the compressed gases of 60–100 MJ is identified where the standardization allows increasing product manufacturing fourfold. All this increases the production performance indicators and stimulates work to improve manufacturing technology for spherical tanks.
