First of all, there is no difference between the structural safety and pressure-bearing safety of the two types of gas cylinders, but there is a significant difference in the design of the two types of gas cylinders and their use.

(1) name: car bottle is used in the car, when leaving the car how to apply for a certificate of use, the current national provinces and municipalities in the implementation of the standard is not uniform, there are still regulatory loopholes. Literally speaking, the name of all the car bottle is “car gas bottle” can be used as a point of supply, gas suppliers or gas users of the gas bottle how to apply for the use of the certificate, we are clear. The full name of the industrial cylinder is “welded insulated gas cylinder” and the filling medium is “LNG”, which determines the legality of the cylinder used in the point supply from the scope of manufacturing license.

(2) The effect of filling: the car bottle is designed and manufactured according to the use of the car, in short, it is a fuel tank (LNG box) you may know more about the fuel tank, the fuel tank is full but not used up, because to a certain amount when the fuel pump can not hit the oil, and the gas cylinder is not full, can burn up the “LNG”, because The vaporization of “LNG” is fast, and the filling volume of gas cylinder is strictly controlled for the safety of using in the car, so that the car bottle can only be filled with 90% of the bottle volume, while the industrial bottle has no limited filling device in the design, so it can be filled with the largest amount. If you consider the longer storage time will increase the pressure emission, you can control the total filling volume.

(3) Use effect: The output of the “car bottle” is the amount of liquid and vaporization of the cylinder designed according to the 100km/gas consumption/time of the vehicle. The values are as follows: The gas consumption is calculated on average for a car with a 450L double bottle set, a heavy car and an empty car, and an average speed of 70 km/h for a distance of 650 km.

The result is as follows: filling volume 450L*90%*0.426T*2 units=345Kg

About equal to 100km/50kg of liquid/70 standard cubes of gas

Liquid consumption per hour: 35kg/49 standard cubes of gas

In the above data, the amount of liquid and gas used can be increased by a small amount. Therefore, there is a certain amount of surplus in the design calculation, and the liquid volume of the vehicle-mounted bottle and industrial bottle is proportional to the volume and pressure of the gasification inlet in the bottle. The liquid discharge volume of industrial bottle has no flow limiting device, and the pipeline is much larger than the diameter of vehicle bottle. The gasification inlet volume is more than 2 times larger than that of the car bottle, which causes the “industrial bottle” to discharge nearly 500 liters of liquid in half an hour, and it can also hold pressure. This function is not inherent in the “car bottle”.

Comprehensive above three levels, it can be concluded that if the security inspection, quality inspection, fire departments do not want formalities, transport costs do not count. If the user’s hourly gas consumption is less than 50 standard cubes, the “vehicle-mounted bottle” can be used.

If you need to go to the regulatory department for legal use procedures, to reduce transportation costs, and to fully cover small and medium-sized (2,000 square meters/day) gas consumption, you must use “industrial cylinders”.
