Cylinder leakage is caused by a long time of cylinder placement and bumps in the process of application or handling. Today I will show you several simple methods to detect whether there is leakage.

1. Sensory method. Adopt the method of ear, ear, nose and smell. If you hear a cylinder "sizzle" and you may smell a strong, pungent odor or foul odor, it is considered a leak. Although this method is very simple, but it has its limitations, toxic gases such as carbon monoxide, methane and some flammable gases are definitely not applicable.

2. Smear method. This is also the most common way we check whether cylinders leak, is to wipe soapy water on the cylinder leak detection point, if there are bubbles, it can be determined as a leak. This method is widely used, accurate, especially need to pay attention to oxygen cylinder leak detection is prohibited to use, because soap water contains oil, oil and oxygen contact is violent oxidation.

3. Ballooning. Place a soft hose on the vent of the cylinder and attach the balloon to the other end. If the balloon expands, it is considered to have a leakage phenomenon. This method is most suitable for highly toxic gas and flammable gas leak detection.

4. Chemical method. The principle of this method is that some prepared chemicals are brought into contact with the gas at the leak detection point, and if a chemical reaction occurs and a certain appearance appears, it is determined to be a leak. If the inspection of ethylene chlorine cylinder can be dipped in cotton ammonia near the leak point, if there is chlorine white fog, that is to prove the leak; The liquid ammonia cylinder can be checked by the red litmus test paper after being wet with water close to the air leakage point of the cylinder. If the test paper changes from red to blue, it indicates air leakage. This method is only used for leak detection of some highly toxic gases.
