How often should gas metal pipes be replaced? How often should gas hoses be replaced?

Generally, it is stipulated that it will be replaced in 2 to 3 years depending on the environment of use. If the hose is not replaced in time, it is easy to produce subtle cracks on it, which is an important hidden danger of gas accidents. It is recommended that the household hose be replaced once every 2 years, and the hose should be stuck with a metal pipe hoop at the joint between the stove and the pipe to prevent the hose from detaching.

The gas pipe connected to the gas stove is generally a rubber pipe, because the gas itself is corrosive, so it is generally recommended to replace it once within two years to avoid potential safety hazards due to serious corrosion.

How often should a metal pipe be replaced with a metal pipe for gas? Generally speaking, it is enough to change it once every five years, if the gas pipe is not a metal pipe, but a plastic pipe or a rubber pipe, then you need to change it every two years.

The air hose should be replaced every one and a half to two years. When replacing the hose, use a hose for gas, if you use a non-gas hose, or if the hose is stiff or cracked, it will be dangerous. The safe length of the hose is in meters.

The best gas metal pipe is 304 stainless steel, 3 belongs to the stainless steel bellows, the service life of this gas bellows can reach more than 50 years, because it has an anti-aging effect. If the family chooses rubber bellows, but it is easy to break in a humid environment, it will gradually age, but 304 stainless steel gas bellows will not have this aging problem.

We recommend that you replace it regularly or simply replace it with a safer metal bellows. Metal bellows has been gradually implemented and used in China since 2010.

It is best to replace it in three years, and you should pay attention to the inspection at ordinary times. If the hose is ***, it may not be bad for more than ten years, and my hose has been used for five years. The connection between the gas meter and the gas stove is the responsibility of the user, and the rubber hose must be replaced once within 18 months according to the city gas management regulations.

It is recommended that the hose be replaced once every 1-2 years. According to the statistical analysis of some gas accidents, gas leakage accidents caused by aging gas hoses or being bitten by rats account for more than 30% of all gas accidents. Generally speaking, the life of gas hoses is only two years, and more attention should be paid to checking whether the hose is aging, wearing, corroded or poorly connected to avoid air leakage.

The following points should be taken into account when replacing the hose:

1) When connecting, a special valve joint should be used, and then fastened with a throat code.

2) The length should be less than 2 meters. The hose shall not be bent, stretched, pedaled, etc., and the cracked and aged hose shall not be used.

3) It should not be installed in the following places: places with flames, radiant heat, and hidden places.

4) Do not fit snugly on the stove. For tabletop cooktops, the hose should not be coiled underneath or crossed, but should be pulled over and bypassed, and if the hose is next from a height, do not allow the flame to ignite. For built-in cooktops, do not fit the hose snugly under the cooktop.

The hose should hang naturally under the cooktop, keep a distance of more than 10 cm, and the length should not exceed 2 meters, so as not to be scorched by fire.

5) After installing the hose, you can use soapy water to check whether there is air leakage. Turn on the gas switch to see if there is continuous bubbling, if there is, it indicates a gas leak and is not safe.

Answer: Replace it every one and a half to two years. Rubber can age, especially in hot, greasy kitchens, where hoses age faster. As the hose ages, its bends, joints, and parts that are often in contact with heat sources are prone to hardening and even cracks.

If you use a non-gas hose, or if the hose is stiff or cracked, it is dangerous.

When installing gas appliances, gas appliances that meet national standards should be used, and it is strictly forbidden to use stoves that do not meet national standards, which will produce harmful gases due to insufficient combustion, which is easy to cause poisoning to indoor personnel.

In daily use, it is necessary to pay attention to inspection and timely repair to prevent gas leakage from gas cooker. The parts that are most likely to leak are: gas meter housing, various connection points on the gas pipeline, valve, hose, etc.

After the gas leak reaches a certain concentration, it will occur when it encounters an open flame**.

Summary. When we choose gas pipes, especially rubber gas pipes, we should look at whether the surface of the pipe is smooth and flat, whether there are blistering and protrusions, and whether there are trachoma and cracks when the gas pipe is bent. The length should not exceed two meters, and it should not pass through doors, windows, walls, etc. when in use, and the hose should be fixed with hoses at both ends.

It should not exceed 2 meters, and there should be no joints or tees in the middle, otherwise it will not only affect the gas consumption, but also easily deform and break the crease of the hose after a long time, resulting in gas leakage. In addition, if the gas pipe is far away from the stove, you can call the gas company and request pipeline transformation to shorten the distance between the two to avoid the gas pipeline being too long and causing potential safety hazards. Normally, the gas pipe needs to be replaced once a year or so, if it is not replaced after the year, it is easy to cause problems such as aging, cracks, and falling off, resulting in gas leakage, so it should be replaced regularly and maintenance should be done.

Before replacing, you should use a tool to measure the distance between the pipe and the stove, or buy according to the size of the old gas pipe, but try to buy products from big brands when buying, so that the quality is more guaranteed. When replacing, use the air valve fitting, and then tighten it with the throat code. When replacing, the length of the pipe should be controlled, not more than 2 meters, and should not be bent or pierced through the wall.

Hello! Dear, I'm glad to let you answer! Hello, the gas steel pipeline is closed for a year and a half to be replaced every two years. Pay attention to the inspection at all times. If the hose is ***, it is possible to use it for more than ten years and it will not be bad, and my hose will be used for five years.

When we choose gas pipes, especially rubber gas pipes, we should look at whether the surface of the pipe is smooth and flat, whether there are blistering and bulging, and whether there are sand fiber hail holes and cracks when the gas pipe is bent. The length should not exceed two meters, and it should not pass through doors, windows, walls, etc. when in use, and the hose should be fixed with hoses at both ends. It should not exceed 2 meters, and there should be no joints or tees in the middle, otherwise it will not only affect the gas consumption, but also easily deform and break the crease of the hose after a long time, resulting in gas leakage.

Normally, the gas pipe needs to be replaced once a year or so, if it is not replaced after the year, it is easy to cause problems such as aging, cracks, and falling off, resulting in gas leakage, so it should be replaced regularly and maintenance should be done. Before replacing, you should use a tool to measure the distance between the pipe and the stove, or buy according to the size of the old gas pipe, but try to buy products from big brands when buying, and the quality of destroying the sail is more guaranteed.

When replacing, use the air valve fitting, and then tighten it with the throat code. When replacing, the length of the pipe should be controlled, not more than 2 meters, and it should not be bent or passed through the wall.

Gas gas hoses should be replaced every 1/2 to 2 years. When replacing, a special gas hose should be selected. It can be dangerous if you use a non-specific gas hose, or if the hose is stiff or cracked.

The safe length of the hose is less than, and if the hose is too long, it passes through the wall or window glass, which is a safety hazard.

And every time you run out of gas, you can't just turn off the stove switch. This is because if an aging hose or cooker cannot withstand the pressure, a gas leak will occur. Especially in winter, when doors and windows are closed, leaked gases cannot escape, and accidents can occur if they accumulate to a certain amount.

Precautions for use.

According to the provisions of the "Management Measures", the "Natural Gas Pipeline Installation Standards" requires that the natural gas pipeline valves installed indoors must be connected or blocked with the gas stove, but valve joints can be required! According to the natural gas pipeline installation standard, when the gas pipeline crosses vertically, the large pipe should be placed in the small pipe.

Outside; When the gas pipeline is laid in parallel with other pipelines, a certain distance should be maintained, and the distance should comply with the provisions of the current national standard GB50028.

Under normal circumstances, natural gas pipes are replaced every 2-3 years.

Generally, the installation is carried out by the installer of the local gas company, and the installation is carried out in an area with a good ventilation system using pipes dedicated to gas. And the joint position between the connecting line and the pipe should be stuck with a metal pipe hoop to prevent the pipe from detaching.

Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced from oil fields) from the extraction site or treatment plant to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. The use of natural gas pipelines to transport natural gas is a way to transport natural gas in large quantities on land. Of the total length of pipelines in the world, gas pipelines account for about half.

Gas hoses should be replaced every one and a half to two years. When replacing the hose, use a hose for gas, if you use a non-gas hose, or if the hose is stiff or cracked, it will be dangerous. The safe length of the hose is within meters, and if the hose is too long and passes through the wall or window glass, it is a safety hazard.

And every time you run out of gas, it is not enough to just turn off the stove switch. This is because if an aging hose or stove cannot withstand the pressure, a gas leak will occur. Especially in winter, when the doors and windows are closed, the leaked gas cannot be discharged, and when it accumulates to a certain amount, it will cause accidents.

There are three types of domestic natural gas pipes. The hose is prone to aging and has risk factors such as breakage and air leakage, and needs to be replaced after more than 18 months of use. Aluminum-plastic pipe.

It can be used for a long time without damage, but the interface should be checked regularly (check with soapy water). Metal bellows, which can be used for 6 to 8 years.

Natural gas refers to all gases that occur naturally in nature, including the atmosphere.

hydrosphere, and lithosphere.

Gases formed by various natural processes (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane and biogenerated gas, etc.).

The long-term common definition of "natural gas" is a narrow definition from the perspective of energy, which refers to hydrocarbons naturally stored in the formation.

Mixtures of non-hydrocarbon gases. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.

On May 6, 2020, PetroChina Southwest Oil and Gas Field Company disclosed that the company had recently discovered a new zone rich in natural gas, with an estimated potential resource of more than one trillion cubic meters.
