How to deal with gas leaks and how to avoid gas leaks

Gas leakage generally means that the air pressure inside the product is greater than the outside gas, and then due to factors such as the pressure difference and the product's own sealing failure, the internal gas leaks out under the action of pressure.

There is another situation of gas leakage, such as vacuum packaging. Because of the vacuum, the air needs to be extracted, and the pressure inside the product will drop. Since the external air pressure will be greater than the internal air pressure, if the sealing of the packaging material or product does not meet the requirements, under the action of the pressure difference, the outside air will flow back into the package or into the product, so it will be impossible to achieve a relative vacuum.This is also the case with gas leaks.It's just gas leaking inward, not outward.

For products with differential pressure, gas leakage must be prevented under normal circumstances, because an important quality indicator of this type of product is that there should be no leakage in one piece.

Reasons why gas leak detection is necessary:

• 1. Gas leakage will cause a waste of costs, especially for gas pipeline valve devices, so we should test its sealing in advance to determine whether the valve is sealed. If the valve is not sealed or the sealing effect is not good, gas leakage may occur. Since such products are generally buried deep underground, if the sealing is not handled before installation, there will be gas leakage during use, resulting in a waste of energy. If it is discovered afterwards, repairing it will require a relatively large amount of work, so it is wise to test its leakage and sealing performance in advance.Shenzhen Hiraysi's gas leakage detection equipment has a type of equipment that specializes in valve sealing and leakage detection. The effect is good and the detection is also very stable.

• 2. Once gases in chemicals leak from the products they contain, the consequences can be serious. Not to mention the difficulty in manufacturing chemical gases, many people know clearly that many chemical gases are highly toxic, highly corrosive, and have strong odors. People are particularly sensitive to these characteristics, because once leaked, it is likely to cause chemical pollution and affect people's health. Maybe one day a chemical crisis will really occur.Therefore, chemical gases must not leak.Then the device in which it is installed must check the tightness to prevent gas from leaking out.The testing requirements are very high.So how to choose gas leak detection equipment?The most famous one in China is the air leakage testing system of Hirays. This air leakage detection equipment originally has a very small internal space, which can ensure the stability and accuracy of the detection. It is the first in the air leakage detection of this type of product.

• 3. Vacuum packaging. Vacuum packaging is generally used for food packaging, pharmaceutical packaging and other products that cannot be exposed to air. Due to the control of gas in the packaging material, the packaging cannot be 100% sealed without air leakage, which affects the shelf life of the product.Therefore, its leakage and seal detection are also very good.Shenzhen Hiraysi's leak detection equipment integrates two positive pressure detection methods. It can perform vacuum detection on packaging materials, or it can also apply pressure from the outside to simulate the external environment for gas leak detection.Convenient and practical.
