Since Safety Month,Frequent and continuous gas explosion accidents occur in various regions know the actual cause.It’s just ‘gas leakage’.How to prevent gas leakage?How to detect gas leaks in a timely manner?How can tetrahydrothiophene make users aware of gas leaks in advance?Let’s explore together:
Gas safety has always been a top priority in our daily lives.
How do we determine if there is a gas leak when using gas?
(1) Smell: Smell if there is an unpleasant odor. Gas itself is colorless and odorless. In order to alert everyone to gas leaks, non-toxic “tetrahydrothiophene” odorants are added to pipeline gas and bottled gas. Once gas leaks, an unpleasant odor will be smelled.
(2) Look: Check if the gas meter reading has changed. If the number at the end of the gas meter rotates when gas is not in use, there may be air leakage in the indoor gas pipeline or equipment.
(3) Apply: Apply “soapy water”. After thoroughly mixing detergent or soap with water, mix it into soapy water, and apply it on the gas pipeline interface. If there are bubbles, it means that the gas is leaking.
Focus on inspecting the following parts:
① Connection between hose and gas appliance
② Connection between hose and valve
③ Connection port between gas pipeline and gas meter equipment
④ Connection ports between gas pipelines
Are you thinking about what “tetrahydrothiophene odorant” is and how it is added to gas?
Let’s follow the editor to further understand the natural gas odorant – tetrahydrothiophene.
Tetrahydrothiophene is a widely used gas odor additive internationally. It has strong antioxidant capacity, stable chemical properties, no residue after combustion, no liquefaction under high pressure, no environmental pollution, and low corrosiveness. It is currently a commonly used gas odorant both domestically and internationally.
Because natural gas itself is odorless, it is easy to explode and burn in case of leakage. For safety reasons, low toxic odorants such as tetrahydrothiophene are added to make it noticeable in the event of a leak. To remind everyone. Of course, tetrahydrothiophene has no residue after combustion. Don’t worry.
Definition of tetrahydrothiophene: An organic compound or mixture with a strong odor. When added to gas at a very low concentration, the gas has a special and unpleasant warning odor, so that the leaked gas is detected when it reaches its lower explosive limit of 5% or reaches the allowable harmful concentration to the human body. With the protection of tetrahydrothiophene in natural gas, let natural gas enter millions of households.
