Cylinder BG-80-40 TU 2296-025-03455343-05

Ballon BG-80-40 is intended for use in the marine environment in the deep-diving complex Dolphin - HVA. The container is designed for cylinder type BMA-160-31, 4, using the same materials. Given the nature of exploitation involves additional protection material liner compounds of zinc, and material power envelope - with special enameled type VC-1236 and CS-5226. The container used to store breathing gas mixtures and oxygen. Cylinders of 80 l, working pressure 40 MPa. Specifications cylinder are given in Table 1. Tests of prototype tanks are planned in the first half of 2007, work on the project funded from the budget and monitored VP MO RF.Zakazchikom work is of "CDB" Lapis ", Nizhny Novgorod.
