How often should the gas hose be changed and how often should the gas hose be replaced

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 standards, when the gas pipeline crosses vertically, the large pipe should be placed outside the small pipe; 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.

It is best to replace the gas hose once a year to about a year and a half. If the ignition hose is not replaced for a long time, it will deteriorate, produce fine cracks, and even fall off, causing gas accidents.

For safety reasons, the hose of natural gas can not exceed 2 meters, and the hose can not cross the doors and windows, after using the gas, the valve of the pipeline should be closed, and only the stove should be closed.

Natural gas is a colorless and odorless gas, but in order to make users aware of gas leaks, hydrogen sulfide is added to natural gas, which tastes similar to rotten eggs, and when users smell similar to rotten eggs, it may be that natural gas leaks.

When natural gas leakage, immediately close the gas switch, close the gas valve, at this time can not easily touch the electrical appliances at home, turn on the lights, open the air conditioner, open the refrigerator, etc. may produce sparks, resulting in **, should immediately open the doors and windows for ventilation, so that the indoor air to keep circulating, in order to reduce the concentration of indoor natural gas.

After opening the window, the occupants should leave the room until the room does not smell the smell of natural gas, then check the cause of the gas leak and deal with it, and if they can't find the problem, they can seek professional help.

1. There are three types of household 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, with a long service life, can be used all the 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.

2. Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane and biogenerated gas, etc.).

3. The definition of natural gas that has been commonly used for a long time is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. 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, 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.

It should be replaced every one and a half to two years. Rubber can age, especially in a hot, greasy environment like the kitchen, 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 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.

Principles for the installation of gas pipes when home improvement:

The installation of gas pipelines is related to the safety of life and property of the owners, so the state and relevant departments have certain regulatory requirements for this. Gas pipelines generally cannot be installed by themselves, so they must be installed first, then the gas company will send someone to lay the pipes into the house, and finally the decoration team will bury the pipes according to the requirements. When burying pipes, the owner must ask a professional installation team to install the gas pipeline system in strict accordance with the standards, and also pay attention to the following points:

1. The pipe can not be installed in the basement of the living room and bedroom, let alone through the power distribution room, air inlet duct and other places, and it is best to be installed in the kitchen, corridor, stairwell and auxiliary room. If there are special circumstances that must cross the above places, there can be no interface in this distance of the pipeline.

2. The distance between the gas pipeline and other pipes such as heating and heating and transmission lines shall not be less than 5cm, and the distance between the gas pipeline and other pipelines such as heating and heating shall not be less than 5cm, and the distance between the distribution box, electrical switches and joints shall be greater than 30cm.

3. The pipeline should be laid on the non-fuel wall, and if the wall near the gas appliance is a flammable material, fire prevention measures must be taken.

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.

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.
