Источники информации, прин тые во внимание при экспертизе; 1. Зарубежное оборудование дл  криоге ных систем. Обзорна  информаци . Издание ЦИНТИ Химнефтемаш, М., 1973, с. 14,18. И Лmediocre beats from opopnegezhnyh layers 9 and 10. Additional heat impermeable dp liquid 9 is located directly on the surface of the rows, layer A of plastic adjacent to the liquid, and complete the 3year drink 1O is part of panel 3. Panels 3 have a frame with 12 channels for the passage of gas, communicating with each other at the contact point of the tubular connectors 13 and, the linker 14 of porous gas-permeable plastic, bounded on one side by a perforated film 15, with a fuse of the stronghold - an additional layer 10 in combination with a gas-permeable a layer consisting of a sintering foil 16 and a polyester film 17. As a filler 14, polyethylene, flexible polyurethane, or a metal scale plate can be used. The perforated film 15 may be made of glass cloth coated with epoxy resin. FIG. Figure 4 shows the results of tensile tests of specimens made of rigid polyurethane plastic with 2 8 O kg / m reinforced with glass fiber mesh with different bipichina cells. Line p on the graph reflects the resistance to the release of reinforced samples, the line of non-reinforced samples. From the graph it follows that the size of the cells of the reinforcing nets 7 and 8 should not exceed 10 mm, preferably 7 mm. In addition, the distance between the additional layers 9 and 10 and the reinforcing meshes 7 and 8 should not exceed 10 mm. According to the invention, the insulating lining of a dp tank with a low-temperature liquid counteracts the additional sinking of the liquid in the event of a tank leak, with the aid of an additional layer 9, reliably. protected by reinforcing mesh 7 when cracks are caused by thermal stress or fluid impact. Through a filler 14 of porous gas-permeable plastic and perforated film 15, a constant flow of ear nitrogen gas is fed at a temperature of about -80 ° C. Each panel 3 has a second hole for nitrogen gas and an outlet connected to the gas analyzer. If a crack arises in layer A of the plastic, the gas resulting from the evaporation of the leaked fluid will pass through a certain panel 3 into the attached gas analyzer, which will ensure the detection of the leakage site within 30 minutes. The leaked fluid that reaches the panel 3 will be held by a second additional liquid-tight layer 10, and the strength of this layer will be reinforced with a reinforced mesh 8. The heat insulating jacket for the low-temperature fluid tank is suitable for use on vehicles for the transport of liquefied gas, providing, with the use of non-combustible materials, enhancing the reliability of the lining and improving the accuracy of determining the places of fluid leakage. The invention of thermal insulation lining for a tank with a low-temperature liquid, in the case of foam plastic layers reinforced with fiberglass mesh, 6 so that the layers of plastic are interconnected mi, imkancimi frame with canadas for the passage of gas and a filler of porous gas-permeable plastic with each layer of plastic on the low-temperature liquid side provided with an additional nym liquid impermeable layer made of a synthetic resin reinforced with fiberglass.
