Standardization of spherical high-pressure vessels comprising composite shells and metallic liners

The standardization of high-pressure vessels (HPV) comprising composite shells and metallic liners is an important problem. However, the literature on choosing the parameters of the standard structures containing compressed and liquefied gases is still lacking. An approach proposed in this paper implies optimizing HPV structural and technological parameters with respect to the cost criterion or technological cost criterion. The latter includes only the cost of winding a composite shell and does not include the cost of materials. The study has shown that: if the cost of materials is high, the second criterion is more sensitive; production expenses can be considerably reduced by implementing automatic winding at a low cost; the zonal winding of high-pressure combined composite vessels provides lower values of tangential stresses as compared to the meridional stresses. The difference between the tangential and meridional stresses increases from the equator to the sleeves. It is characteristic for the zonal winding that the meridional stresses oscillate in the angular coordinate. Their amplitudes increase with decreasing the number of winding zones. The thickness of the liner near the sleeves is chosen from the condition that the composite structure could withstand angular loads. The liner thickness variation law is suggested. The proposed recommendations concerning the HPV design and technology standardization will significantly reduce production costs in mechanical engineering.
Keywords: high-pressure vessel, composite shell, liner, optimization, structural and technological parameters, technological costs, winding a composite shell, strength of a combined structure.
