This utility model refers to the field of transport, storage and supply of gas and, specifically, to a gas cylinder. In particular, the present utility model refers to a cylinder for compressed (pressurized) gas.

10 Background of the invention

In the prior art, cylinders are known, designed for transport, storage and gas supply.

15 Currently, for the purposes indicated above, cylinders of four types are used: type 1 - seamless steel cylinders; type 2 - cylinders composed of a metal lining and a composite (composite) shell covering the surface of cylindrical lining; type 3 - cylinders composed of a metal lining and a composite (composite) shell covering the entire lining surface; Type 4 - cylinders composed of a non-metal lining, a composite (composite) shell that covers the entire lining surface and metal inserts.

In general, such gas cylinders optionally comprise at least one neck for gas injection into the cylinder and releasing gas from it.

25

An example of such a cylinder is described in EP1526325. The gas cylinder comprises an impermeable shell of an aluminum-containing material, a cargo shell wrapped in composite (composite) material, a plastic cover along the inner surface of the waterproof shell and a neck with a thread to connect a 30 shut-off valve.

For the transport and storage of such gas cylinders, cargo containers with specific parameters are used, for example series 1 cargo containers with a length from 2,986 mm to 2,991 mm (according to GOST R 53350-2009), width 35 with value from 2,433 mm to 2,438 mm (according to GOST R 53350-2009) and height with a value from 2,891 mm to 2,896 mm, or length with a value from 6,052 mm to 6,058 mm

(according to GOST R 53350-2009), width with value from 2,433 mm to 2,438 mm (according to GOST R 53350-2009) and height with value from 2,891 mm to 2,896 mm, or length with value from 9,115 mm to 9,125 mm (according to GOST R 53350-2009), width with value from 2,433 mm to 2,438 mm (according to GOST R 53350-2009) and height with value from 5 2,891 mm to 2,896 mm (according to GOST R 53350-2009).

Currently, known twenty-foot containers are used for gas cylinders that are manufactured by Xperion, for example, X-Store type containers with a total cylinder capacity of 19,250 liters capable of accommodating 5,650 m3 of natural gas contained in 55 10 cylinders positioned vertically with an outside diameter of 505 mm, capacity of 350 liters each, and operating pressure of 250 bars, or by Hexagon, for example Smartstore type containers with the total cylinder capacity of 18,000 liters capable of accommodating 5,400 m3 of natural gas contained in 40 cylinders positioned horizontally with a capacity of 450 liters each and an operating pressure of 250 bars.

In the absence of standard tubes with the outer diameter of 453 mm, the calculation was carried out for a tube with the diameter of 450 mm.

5 In which:

D1 - outer diameter of the gas cylinder 1;

Dbo - outer diameter of inner shell 3;

N - number of gas cylinders 1 in container 8;

10 L2 - length of the inner frame 3;

V6 - gas cylinder capacity 1; m6 - mass of gas cylinder 1;

Vk - total container capacity 8.

15 The calculations and experiments confirm that the maximum capacity of the container 8 with the specified parameters comprising the gas cylinders 1 is achieved with the following characteristics of the cylinder 1: the outer diameter D of the gas cylinder 1 ranging from 480 mm to 520 mm, the capacity of the gas cylinder 1 ranging from 350 liters to 430 liters if the gas cylinders 1 are positioned vertically and arranged in a board pattern in the container 8.

As shown in Table 5, such a combination of gas cylinder parameters (the

outer diameter of 520 mm and capacity of more than 350 liters) provides an increase in the capacity of a container so that the gas cylinders they provide are contained within the container with the specified parameters (a standard twenty-foot container) due to the The fact that with such cylinder parameters 55 the 5 gas cylinders can be contained in the container with the specific parameters and in this case if a gas cylinder with a capacity of more than 350 liters (for example, 351 liters) is used The capacity of the container would be more than 19,250 liters (for example, 19,305 liters for gas cylinders with the capacity of 351 liters), which is more than in the documents of the prior art.

10

On the other hand, the outer cylinder diameter of 520 mm allows to increase the capacity of the gas cylinder to 430 liters (with the inner cylinder diameter of 490 mm) that provides the container capacity of 23,650 liters which is significantly greater than the capacity of a container with the same size described in the documents of the prior art.

In this way, a way of arranging 55 gas cylinders with the outer diameter of 530 mm in a twenty-foot container and at the same time increasing the capacity of a cylinder with the outer diameter of 520 mm to 430 liters has been demonstrated.

twenty

It is obvious that with the decrease in the diameter of the outer cylinder (that is, with the values of the outer diameter less than 520 mm) at least 55 gas cylinders can still be contained within a container with the specified parameters that also provides an increase in the capacity of a container with the specified parameters 25 to more than 19,250 liters. In addition, with the decrease in the outer cylinder diameter to 480 mm its capacity can be increased to 430 liters (with the inner cylinder diameter of 470 mm). By providing at least 55 of said cylinders contained within a twenty-foot container, its capacity would be increased to 23,650 liters, which is significantly greater than that achieved in the state of the art documents (19,250 30 liters).

It is clear that all intermediate combinations of the declared parameters also provide, first, the arrangement of at least 55 gas cylinders in a twenty-foot container and, secondly, an opportunity to increase the capacity 35 of a gas cylinder with the outside diameter from the declared interval (including the minimum value) to any value of the declared interval (including the maximum value).

Thus, any combination of cylinder parameters (the outside diameter from 480 mm to 520 mm and capacity ranging from 350 liters to 430 liters) provides the technical result.

In a preferred embodiment, the inner frame has the length L2 in the range from 2,400 mm to 2,870 mm, inner diameter at least 420 mm and outer diameter not more than 520 mm.

In a preferred embodiment, the total length of the gas cylinder 1 ranges from 2,450 mm to 2,896 mm.

Table 6 provides the main characteristics of the gas cylinder 1 according to a preferred embodiment.

According to the present utility model, the gas cylinder 1 is designed for gas injection into it, gas storage, gas transportation and gas supply therefrom.

In table 6, the total length L1 of the cylinder 1 should be interpreted as the length of the cylinder 1 with valves and clamping units mounted on its necks.

The gas injection into the gas cylinder 1 and the gas supply from the gas cylinder 1 are carried out by using the shut-off and safety valves of the gas cylinder 1. The processes can be controlled by means of pressure gauges or other suitable devices, 15 if required.

It should be noted that the described gas cylinder is only one of the preferred embodiments. It is obvious to one skilled in the art that variations and modifications can be made in the present invention without departing from the scope of protection defined by the appended claims.
