FIELD: compressed gas equipment. SUBSTANCE: vessel has cylindrical shell in the form of spiral and ring layers made of a fiber composite material and bottoms formed by spiral layers. The bottoms are provided with insertion members. There are additional ring layers in the zones adjacent to the bottoms of the cylindrical load-carrying shell. The length of each zone is 0.6-1.5 of the radius of the cylindric load-carrying shell. The number of additional layers is 10-30% of the total number of ring layers. The additional ring layers alternate with spiral layers of the load-carrying shell. EFFECT: enhanced safety. 4 dwg
