Why can't liquefied gas cylinders be placed sideways

　　Liquid gasification danger: Because the liquefied petroleum gas in the liquefied petroleum gas cylinder is a high-pressure liquefaction method (its original volume is compressed to 1/250), it is poured into the steel cylinder. Once the steel cylinder is placed horizontally, the liquid will immediately flow into the atmosphere and will expand immediately. 250 times, if there is any fire source during the expansion process, it will be dangerous;

　　Risk of heat generation due to friction: when the LPG cylinder is standing, the contact area between the liquid and the gas is small, which is safe; if it is placed horizontally, the contact area between the liquid and the gas is large, which is more dangerous; especially when it is shaken horizontally, the friction area between the liquid and the gas expands 3. The increased frequency will make the liquid vaporize and pressurize and affect its safety. If there is a heat source nearby, there is a danger of explosion;
　　The on-off valve is easy to be damaged: a large amount of heat will be absorbed during the process of changing from compressed liquid to gas. If it leaks horizontally, so that the liquid contacts the cylinder valve, it will cause the outlet to freeze and fail to perform its normal function of controlling flow;
　　Fragmentation of safety gasket: when placed horizontally, it is easy for liquid impurities or oil on the inner and bottom of the cylinder to contact the on-off valve, causing the valve to block and lose the normal flow control function, or lost due to the plastic gasket of the valve touching the liquid debris Stop leak function;
　　Safe pressure relief design: when the liquefied steel cylinder is stored, the liquid exists in the lower half, and the gas is in the upper half. To balance the internal pressure, when there is pressure relief, it should be discharged to the weakest pressure, so all cylinder valves are designed At the uppermost end, in case of failure or unexpected situation, the pressure can be released from the upper end without affecting the surrounding environment and the safety of the operating personnel.

Correct use of liquefied gas cylinders

　　 Correct use of liquefied gas cylinders 　　In rural areas, almost every household now uses bottled liquefied gas. Generally, every household uses a bottle of liquefied gas and stores another bottle of liquefied gas at home. More than a decade ago, most families would go to the filling station to replace the bottled liquefied petroleum gas. Nowadays, the household bottled liquefied petroleum gas is mainly replaced by the gas provider driving the battery tricycle. 　　1. Liquefied gas cylinders should be placed in a place that is easy to move, ventilated and dry, and not easy to corrode. It is forbidden to be placed in a sealed cabinet; 　　2. Liquefied petroleum gas cylinders are strictly prohibited from being exposed to the sun, near open flames or places with high temperatures, and forbidden to grill with fire or pour with boiling water; 　　3. The liquefied gas cylinder should be used upright, and it is strictly prohibited to use it upside down or lying down; 　　4. LPG cylinders are strict...

Unexamined LPG cylinders are tantamount to bombs

　　It is understood that the service life of the general liquefied gas cylinders is 15 years, and the steel cylinders with a capacity of 15 kg and 5 kg must undergo a mandatory "physical examination" every 4 years, and the 50 kg steel cylinders need to be tested every 3 years. 　　The current safety hazards of liquefied gas cylinders are mainly due to overdue inspections and don’t sell them to individuals after they are scrapped. Many people have misunderstandings about liquefied gas cylinders. Some citizens once stored scrapped steel cylinders at home or sold them to private individuals to allow scrapped cylinders to continue to circulate in the market, which are likely to cause safety accidents. The quality inspector said that many people think that they have run out of liquefied gas, or open the valve to release the gas, and there is no liquefied gas in it. This view is not correct. Scrapped steel cylinders are deflated by special tools in the laboratory, and there will stil...
