Can gas pipelines go into underground space

Yes, natural gas pipelines are generally laid in the ground.

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.). And people have been common for a long time"Natural gas"The definition 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.

Natural gas is contained in underground porous rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcanic gas and biogenerated gas, and a small amount also comes from coal seams. It is a high-quality fuel and chemical feedstock.

Natural gas is mainly used as a fuel to make carbon black, chemicals and liquefied petroleum gas.

Propane produced from natural gas.

Butane is an important raw material for modern industry. Natural gas is mainly composed of gaseous low-molecular-weight hydrocarbons and non-hydrocarbon gases.

It's no problem at all, it's all underground complexes now, and all kinds of pipes can be placed underneath, which is beneficial to the impact of ground traffic or aesthetics.

Natural gas pipelines are generally buried laying, whether it is long-distance pipeline transportation, or urban pipeline network construction, are buried laying, only when the residential user is in the home is laid with open pipe, and the hose of the household gas stove must be laid with open pipe according to the specification, and it must be replaced regularly.

I don't know if what I explained is different from the "underground space" you asked.

Natural gas exploitation companies are illegal, as long as there are pipes, there are potential safety hazards, and there are harm to the personal safety of our citizens, and they should be severely punished, and it is not up to them to have the final say.

Hello, the minimum covering thickness (pavement to pipe top) of the underground burial of natural gas pipelines should meet the following requirements:

The pipe should be buried centimeters deep when it goes from under the soil.

This should be a place that motor vehicles can't reach, at least meters.

How many centimeters do you have to bury the 8 cm trachea to the motorway from the ground?

The lower edge of the buried motorway shall not be less than meters, that is, it shall not be less than 90 centimeters.

Summary. The minimum covering thickness for buried underground gas pipelines shall meet the following requirements:

What is a gas pipeline:

Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced by oil fields) from the extraction site or treatment plant to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. Pipelines are the only 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.

Features of the gas pipeline:

1.The gas pipeline system is a continuous and closed transmission system.

2.From transportation, storage to user use, natural gas is under pressure.

3.Due to the small specific gravity of the natural gas transported, the influence of the static pressure head is much smaller than that of the liquid, and when the height difference is less than 200 meters during the design, the static pressure head is negligible, and the line is almost not limited by the longitudinal terrain.

4.There is no liquid pipe water hammer hazard.

5.When an accident occurs, it is harmful and has a wide range of effects. Once the pipeline is ruptured, the release energy is large, the tearing length is long, and the discharged natural gas is easy to cause a fire in case of open flame.

How deep are gas pipelines buried underground?

If it is located under the roadway, the pipe should not be lower than the meter. If it is located under a non-roadway, the pipe cannot be lower than the meter. If it is to be located in a place that cannot be reached by motor vehicles, the depth shall not be less than meters. If it is located under a paddy field, the depth must not be less than meters.

Can the natural gas main line go indoors? Kiss! Hello, glad to answer for you.

If the owner has any objection to this, the owner can negotiate with the developer and the gas company, and after joint consultation, formulate a feasible plan to renovate and install the pipeline to meet the requirements of the owner. The gas pipeline main can only be installed on the exterior wall, and the gas meter and other equipment can only be installed on the balcony, and the natural gas main pipe can no longer be installed indoors. Article 30 of the Regulations on the Administration of Urban Gas stipulates that the installation, modification and dismantling of indoor gas facilities shall be carried out in accordance with the relevant national engineering construction standards.

Article 44 stipulates that in violation of the provisions of these Regulations, the local people's ** at or above the county level and their gas management departments and other relevant departments do not make administrative licensing decisions or handle approval documents in accordance with the law, if they discover illegal acts or receive reports of illegal acts and do not investigate and deal with them, or if they fail to perform their duties in accordance with the provisions of these Regulations, the directly responsible person in charge and other directly responsible personnel shall be punished according to law; Where the conduct of the directly responsible managers and other directly responsible personnel constitutes a crime, criminal responsibility is pursued in accordance with law. Hope mine can help you! Do you have any other questions?

No, the "Code for the Installation of Natural Gas Indoor Pipelines" is as follows:

1. The gas inlet pipe shall not be laid in the bedroom, bathroom, flammable or explosive materials.

Warehouses, rooms with corrosive media, power generation rooms, distribution rooms, substation rooms, air-conditioning rooms that do not use gas, ventilation rooms, computer rooms, cable trenches.

Heating ditches, flues and air inlet ducts, roads, etc.

2. The residential gas inlet pipe should be located in the kitchen, corridor, and closed balcony connected to the kitchen (the balcony should be closed when transporting wet gas in cold areas) and other non-residential rooms that are easy to maintain. When it is difficult, it can be introduced from the stairwell, but metal pipes should be used and the entry pipe valve should be located outdoors.

3. The gas inlet pipe of commercial and industrial enterprises should be located in the room or gas meter where the gas is used.

room. 4. The gas inlet pipe should be introduced through the wall along the ground of the outer wall. The upper end of the outdoor exposed pipe section should be cleaned with tee and wire plug not less than DN15, and anti-corrosion treatment should be done. Wet gas should be kept warm when transporting in cold areas.

Summary. Yes, through careful combing of China's current pipeline specifications or standards, no current specifications or standards have been found to clearly stipulate that gas pipelines cannot enter the underground comprehensive pipe gallery. However, it is clearly stipulated in the authoritative specification of the current "Technical Code for Comprehensive Pipe Corridor Engineering" GB50838-2015 that gas pipelines can enter the underground comprehensive pipe gallery, as described in Article 1

Water supply, rainwater, sewage, reclaimed water, natural gas, heat, electricity, communications and other urban engineering pipelines can be included in the comprehensive pipe corridor.

Hello. Please speak.

What are the hidden dangers of leakage of high-pressure natural gas pipelines buried underground; Recently, I often hear about pipes**; In this way, the buried Guan Shijinzhou Road is not the first to be annihilated by a time bomb.

There is a high-pressure pipeline buried in the ground next to my house; It's a bit scary.

Always worry that the pipe will leak that day; **Finish.

Can you explain your teacher's concerns?

Don't worry, the state is very strict about this area, and the standards are very high.

As the saying goes, 10,000 is only afraid of what if; Suppose it says there is an air leak; how we find out; There was also gas coming into our room; Whether there are potential safety hazards when we use open flames?

If so, there is a safety hazard.

Summary. It is safer to install natural gas pipelines in the air or buried underground, of course, it is safer to be buried underground.

It is safer to install gas pipelines in the air or buried underground.

It is safer to install natural gas pipelines in the air or buried underground, of course, it is safer to be buried underground.

Hello, what do you call it?

Dear, I'm the answerer, gradually Cuixuan.

Buried well, but also look at the material, buried pipeline materials may be made of stainless steel or hot plastic, buried is also relatively deep, I see a buried at least 3 meters deep, overhead with ordinary iron pipe, will rust the kind, but the outside is painted, but can not withstand the wind and rain and rain, a smile to use it is very cool, it is more than 10 years, iron pipe corrosion, air leakage is late, frequent maintenance, it is troublesome, Ken Bureau Dan will often stop gas.

Some of us here have to say that the rack is safer in the air, and use galvanized pipes, which can be used for more than 30 years.

Dear, did you see the last one I posted?

I've read the previous one, dear, you said that the pipe can be overhead.

That's what I told them, but they didn't admit it.

But it is not clear whether it will last for 30 years.

Dear, generally overhead wind and rain, you feel that it can be used for 30 years.

The pipe was also an iron pipe, but there was a layer of zinc on the outside. Can it be used for more than 30 years?

Pro, generally about 10 years.

Summary. If the depth of the natural gas underground pipe is greater than the depth of the foundation of your house, that is to say, the natural gas pipeline passes under the foundation of your house, then there is basically no harm to the house, such as insufficient depth, and the natural gas underground pipe passes through the foundation of the house, which will cause slight damage to the house. But it's fine to tinker properly.

In addition, there are safety measures for natural gas pipelines, so you don't have to worry too much about it.

Can an outdoor gas pipeline be buried under the foundation of a house, and is it dangerous?

Oooh. If the depth of the natural gas underground pipe is greater than the depth of the foundation of your house, that is to say, the natural gas pipeline passes through the rock under the foundation of your house, then there is basically no rough harm to the house, such as insufficient depth, and the natural gas underground pipe passes through the foundation of the house, which will cause slight damage to the house. But if you fix it properly, it's no problem.

In addition, there are safety measures for natural gas pipelines, so you don't have to worry too much about it.

Outdoor gas pipes can be buried under the foundation of the house, oh, dear, no problem.

Not because of accidents**.

? No, there are corresponding installation specifications.

The gas pipeline is buried under the road, and it's okay if there is a car passing by every day.
