What is the pressure in a gas pipe? What is the pressure of natural gas?

The current "Code for the Design of Urban Gas".

The first article of GB50028 divides urban gas pipelines into seven levels according to the gas design pressure P (unit: MPA).

1. High-pressure gas pipeline class A: pressure is 2, high-pressure gas pipeline class B: pressure is 3, sub-high pressure gas pipeline class A: pressure is 4, sub-high pressure gas pipeline class B: pressure is 5, medium pressure gas pipeline class A: pressure is 6, medium pressure gas pipeline class B: pressure is 7, low-pressure gas pipeline: pressure is P<.

Among them, the household is generally used for low-pressure gas pipelines, because the general residential natural gas cooker is rated at 2000pa; Gas pipelines in municipal networks generally use high and medium pressures.

Gas pipeline pressure high pressure, sub-high pressure, medium pressure, low pressure, .

A pipeline is a device made of pipes, pipe connectors, valves, etc., which is used to transport gases, liquids, or fluids with solid particles. Gas pipelines are pipes used to transport gas, which are mostly laid underground. The urban gas pipeline network is like the "blood" of the city, and it is very important to ensure the safe operation of the pipeline network.

China's urban gas pipelines are divided into four levels according to pressure. That is: low-pressure, medium-pressure, sub-high-pressure, high-pressure gas pipelines.

The pressure of piped natural gas for general household use is 2000kpa.

The low-pressure pipeline natural gas to the home, because the general residential natural gas cooker is rated at 2000pa, and there are factors such as the pressure drop of the pipeline, the general pipeline pressure is adjusted to 3000pa. (One atmosphere.)

is 100,000 pascals). The natural gas pipelines of the municipal pipeline network are also divided into high pressure and medium pressure, etc., and there is a specific range of pressure levels.

In China, the pressure range of urban pipe networks: 005-0 .

4MPa, after adjusting the pressure to 2-3kpa (generally 2.).8kpa) into the pre-stove pipe; The rated outlet pressure of the natural gas stove is 2kpa, once the pressure regulator fails or other reasons make 005-0 .

The pressure of 4MPa is connected to the low-pressure gas pipeline, which will cause the natural gas stove to leak because it cannot withstand this high pressure, and the danger may occur in serious cases.

The pressure is different for different applications, and it is meaningless not to specify the application problem, only examples.

Civilian 2 3kpa, above 2000kpa, I'm afraid it's not going to die of laughter, and the layman can't copy it blindly.

The medium pressure gas supply of urban gas is 10kpa

The long-distance output can reach more than 10MPa.

Compressed natural gas tens of MPa is also common.

You deleted the first sentence, 2000kpa is 2mpa, which is higher than the gas of high-pressure pipelines.

1. The pressure level of gas pipelines is divided into several levels Article 1 of GB50028 in China's current "Urban Gas Design Code" divides urban gas pipelines into seven levels according to the gas design pressure P (unit: MPA): 1. High-pressure gas pipeline Class A: The pressure is.

How would you rate this?

Collapse the "Gas Engineering Project Code" GP55009-2021, which will be implemented from January 1, 2022. The pressure piping is graded as follows:

"Code for Gas Engineering Projects" GP55009-2021 "Code for Design of Urban Gas" GB50028-2006 [2020 Edition] The pressure pipeline classification is as follows:

Generally 1500 3000paThe medium pressure of municipal pipelines is generally as follows. Through the pressure regulator box of the building, it depends on how much your local company is set up.

Wuhan seems to be more than 2000pa. The higher the pressure setting, the greater the difference between supply and supply. Bad for gas companies.

High-pressure, medium-pressure and low-pressure pipelines are all pressure pipelines, which refer to all pipelines subjected to internal pressure or external pressure, regardless of the medium in the pipe, used to transport gases, liquefied gases, vapors or flammable, explosive, toxic, corrosive, and liquid with a maximum working temperature higher than or equal to the standard boiling point, and the nominal diameter is greater than or equal to 50mm.

A kind of gas pipeline, according to the pressure of the gas in the pipeline can be divided into high-pressure pipeline, medium-pressure pipeline and low-pressure pipeline, the greater the pressure, the stronger the gas transmission capacity, the higher the requirements for the pipeline.

In gas engineering, according to different pressures, it is divided into medium pressure, high pressure and low pressure.

Medium pressure can be divided into medium pressure A and medium pressure B.

Generally, the medium-pressure pipeline is located between the "gate station" or the gas company that produces natural gas and the pressure regulating meter of the residential building.

Medium-pressure pipes can be steel pipes, or PE pipes.

The specific pressure value shall be subject to the national standard.
