Simple tips to distinguish genuine gas cylinders
(Baonghean.vn) - In order to earn high profits, many manufacturing facilities have disregarded the danger to customers and sold fake gas cylinders with low quality gas to the market. Therefore, consumers need to know how to distinguish genuine gas from fake gas to ensure safety.
Observe the shell
 |
Normally, a standard cylinder will have the brand name embossed on the shell. Inside is a confirmation letter, the gas cylinder body is stamped with a steel mold. Then the shell is inspected and pressure tested… before it can contain gas and be sold on the market.
The embossed letters on the top of the fake gas cylinders from the genuine manufacturer will be stamped out, even burned, the valve removed, the base replaced, and then welded again... to erase all traces of the genuine gas cylinder, replacing it with the name of another unit.
Consumers need to be alert to strange signs of the product such as: gas cylinders lighter than normal, unclear logos, lead seals, inconsistent shrink wrap, etc.
Check the weight of the tank
 |
On the handle of each gas cylinder, depending on the company, the weight of the cylinder is written from 12.5kg-13.5kg. For the common 12kg gas cylinder, the total weight of the cylinder and the gas inside will be 24.5kg-25.5kg.
Therefore, when buying gas, customers need to ask the gas staff to weigh the gas cylinder, subtract the total weight of the gas cylinder from the weight of the shell written on the handle to know the amount of gas in the cylinder.
Pay attention to the expiration date
 |
People often think that gas cylinders are made of steel and have anti-corrosion materials added so they can be reused for many years, but in fact, gas cylinders also have a certain shelf life.
In addition to the brand, the safety of a gas cylinder is also shown by the inspection date printed on the cylinder handle. For example, if the cylinder handle has the code 18A, the user can use the cylinder until the first quarter of 2018.
Distinguishing through anti-counterfeit stamps
Anti-counterfeit stamps are produced with advanced printing technology, issued and managed by the Institute of Criminal Science - Ministry of Public Security. In addition to the printed part that can be identified by the naked eye, the stamp has an anti-counterfeit feature: the logo only glows under ultraviolet light. In this way, consumers can immediately determine whether it is a genuine gas cylinder or a counterfeit gas cylinder.
The stamp will be affixed to 2 products currently sold on the market: Household gas - 12kg and 11.5kg cylinders, and industrial kitchen gas - 45kg cylinders.
Know the address of the gas dealer and store
 |
When ordering gas, consumers often do not pay attention to the brand but only order gas based on the color of the tank such as gray tank, blue tank, red tank, etc., creating conditions for fake gas traders to sell poor quality and unsafe products.
According to branded gas companies, when buying gas, you need to know the address of the gas dealer or store, you should not just call by phone; when approaching advertising leaflets, you need to be careful and ask carefully for the address because most of them only print wireless or mobile phone numbers; when you see something suspicious, you must ask to see the documents and cards of the gas delivery staff and verify the gas dealer's hotline number.
