It has become the development direction of clean fuel for automobiles in the world, and natural gas vehicles have become the fastest-growing and most widely used new energy vehicles.

[0003] Natural gas is a gas fuel. Once it leaks, it will cause safety problems such as combustion or explosion. For the storage of natural gas, seamless steel cylinders are mostly used both at home and abroad. In view of the particularity of the natural gas medium and from a safety perspective, both internationally and domestically, special regulations have been made for natural gas storage cylinders, and corresponding standards have been formulated separately. These standards all clearly require that natural gas cylinders must meet the fire test requirements.

[0004] Regarding the fire test requirements, the cylinder should be placed horizontally with the bottom of the cylinder approximately 100 mm above the fire source. At least three thermocouples should be evenly set along the bottom of the cylinder to monitor the surface temperature. After ignition, the flame should quickly spread over a length of 1.65 m and surround the bottom and both sides of the cylinder. Within 5 minutes after ignition, at least one thermocouple should indicate a temperature of 590 ° C, and the temperature should not be lower than this during subsequent tests.

[0005] For steel cylinders with a length of no more than 1.65m, the center position should be placed above the center of the fire source; for steel cylinders with a length of more than 1.65m, if a pressure relief device is installed at one end of the cylinder, the fire source starts at the other end of the cylinder; if pressure relief devices are installed at both ends of the cylinder, the fire source should be located at the center between the pressure relief devices; if the cylinder is additionally protected by an insulation layer, two fire tests should be carried out under working pressure: one with the center of the fire source located in the middle of the length of the cylinder, and the other with another cylinder so that the fire source starts at one of the two ends of the cylinder.

The fire test equipment needs to be adapted to natural gas cylinders of different diameters and lengths. When testing natural gas cylinders of different diameters and lengths, different fire test equipment needs to be replaced, which is rather troublesome. Utility Model Content
