Now most of the residents in small cities and above use pipeline gas. Unlike bottled liquefied gas, a pipeline of natural gas goes directly to the home, eliminating the trouble of replacing gas cylinders.
However, as gas, although natural gas is more efficient, pipeline gas also has great safety hazards, and the biggest hidden danger is the gas hose.
The gas hose is an indispensable key component in the use of gas, so its safety is directly related to the safety of the use of gas. According to the national standard, the gas hose shall not exceed 2 meters, and it has always been said that it cannot exceed 2 meters. What is the reason for this?
It is estimated that not many people know, because they do not pay much attention to this gas hose in normal use. If the gas hose is too long, it will increase the resistance of the intake pipe, reduce the transmission pressure, and reduce the heat loss of the stove.
If the gas hose is too short, it will cause a pulling phenomenon, and the gas hose hose is easy to fall off. Moreover, the rubber gas hose usually used needs to be replaced every two years at most due to its service life.
Because the life of the rubber gas hose is very short, only 18 months, and the rubber gas hose can only be used for two years at most. Serious overdue use will only bring unforeseen safety hazards.
Therefore, the rubber gas hose should be checked regularly, and the rubber gas hose should be replaced in time if it is found to be aging, cracked, scorched, and bitten by mice, so as to avoid greater irreversible gas accidents.
The gas hose should not be too long, which is not only a requirement for rubber gas hoses, but also a requirement for stainless steel corrugated gas hoses.
Although the stainless steel corrugated gas hose has strong stretchability, the stainless steel corrugated gas hose can also compensate for the dislocation caused by the displacement of the object to a certain extent, and prevent the gas hose from breaking and leaking.
However, according to the regulations, the stainless steel corrugated gas hose can still not exceed 2 meters. If the gas stove is far away, the stainless steel corrugated hose for gas transmission can be used to connect the gas source, and then the stainless steel corrugated hose can be used to connect the stove.
Although the gas hose cannot exceed 2 meters, the stainless steel corrugated hose is more recommended than the rubber hose. The stainless steel corrugated gas hose is a special gas hose for pipeline gas, which is safer and more durable.
The service life of stainless steel corrugated gas hose is generally about 8 years, and it has no common defects such as aging. It is the gas hose commonly used in natural gas at present.
