First of all, there is no difference between the two types of gas cylinders in terms of structural safety and pressure-bearing safety, but there is a significant difference between the two types of gas cylinders in terms of design and use.
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 cities in the implementation of the standard is not uniform, there are still regulatory loopholes. From the wording, the name of all the car bottle is “car natural gas bottle” can be used as a point of supply, gas suppliers or gas users how to apply for the use of gas cylinders, 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 use of the cylinder in the point supply from the scope of manufacturing license.

Filling effect: The car bottle is designed and manufactured according to the use of the car, in short, it is a fuel tank (LNG tank) you may know more about the fuel tank, the fuel tank is full but can not be used up, because to a certain amount of fuel pump can not hit the oil, and the gas cylinder is not full, can be burned out of the “LNG”, because the “LNG” of the “LNG”. Because of the fast vaporization of “LNG”, the filling volume of gas cylinders is strictly controlled for the safety of use in the car, so that the car bottle can only be filled with 90% of the bottle volume, while the industrial bottle is not designed with a limited filling device and can be filled with the largest amount. If you consider the longer storage time will pressurize the emission, you can control the total filling volume by yourself.
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 model. The values are as follows: the car with 450L double bottle set, heavy and empty car average calculation of gas consumption, the average speed of 70 km/h can travel 650 km as a premise.
The results are as follows: filling volume 450L * 90% * 0.426T * 2 units = 345Kg
Approximately equal to 100km/50kg of liquid/70 standard cubes of gas
Liquid consumption per hour: 35kg/49 standard cubic meters 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 vehicle-mounted bottle and industrial bottle is proportional to the volume and pressure of gasification inlet in the bottle. The liquid discharge volume of the industrial bottle has no flow limiting device, and the pipeline is much larger than the diameter of the car bottle, which can be discharged smoothly in the pipeline with an inner diameter of Ø14.5. The gasification inlet volume is more than 2 times larger than that of the car bottle, resulting in the “industrial bottle” being able to discharge nearly 500 liters of liquid in half an hour, and it can also hold pressure. This function is “car bottle” innately does not have.
Comprehensive above three levels, it can be concluded that if the security, 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, reduce transportation costs, and fully cover small and medium-sized (2,000 cubic meters/day) gas consumption, you must use “industrial cylinders”.
