Cylinder BG-80-20 TU 2296-018-03455343-06

 

In the autumn of 2009, "NPO" POISK "began to develop a new type of cylinder. These cylinders for compressed air are designed to operate in conditions of sea water in deep-sea submersible vehicles. Consigned to store compressed air pressure to 20.0 MPa in the product Triton -NN.
Deep-water tanks have a capacity of 80 liters and a working pressure equal to 20 MPa. The length of one cylinder 1354mm, its outer diameter 317 of 2 mm and the weight 46.6 kg. The container has two neck threaded M30h2.
