When is the natural gas pipeline in the community generally entered the site for construction

After the installation of outdoor natural gas pipelines in the residential area and outdoor water supply and drainage, heating, fire protection and other pipelines, as well as strong and weak current pipelines, the construction of residential roads, hard pavement and greening will begin before construction.

Natural gas pipeline transportation has the advantages of low transportation cost, less land occupation, fast construction, large oil and gas transportation volume, high safety performance, less transportation loss, no "three wastes" discharge, small leakage risk, little environmental pollution, less impact on bad weather, small amount of equipment maintenance, easy management, and easy to realize remote centralized monitoring.

Classification of uses. Gas pipelines can be divided into three types according to their uses: gas gathering pipelines, gas pipelines, and gas distribution pipelines.

1. Gas gathering pipeline: the pipeline from the wellhead device of the gas field through the gas gathering station to the gas processing plant or the starting point compressor station, which is mainly used to collect untreated natural gas extracted from the formation. Due to the high pressure of the gas well, the pressure of the gas gathering pipeline is about 100 kgf cm2 or more, and the pipe diameter is 50 150 mm.

2. Gas transmission pipeline: from the gas treatment plant or the starting point compressor station of the gas source to the gas distribution center of major cities, the pipeline of large users or gas storage, as well as the pipeline that is connected to each other between the gas sources, and the natural gas that meets the quality standards of pipeline transportation after treatment is the main part of the entire gas transmission system.

The diameter of the gas pipeline is larger than that of the gas gathering and distribution pipes, and the largest gas transmission pipeline has a pipe diameter of 1420 mm. Natural gas is pressurized and transported by compressor stations at the starting point and along the line, with a transmission pressure of 70 80 kgf cm, and the total length of the pipeline can reach thousands of kilometers.

3. Gas distribution pipeline: the pipeline from the urban pressure regulating and metering station to the user's branch line, the pressure is low, there are many branches, the pipe network is dense, the pipe diameter is small, in addition to a large number of steel pipes, the low-pressure gas distribution pipeline can also be used plastic pipes or other material pipes.

If it is a project under construction, it is generally after the completion of the main body of the project, after the blueprint comes out, the hydropower will be constructed together, so as to ensure that the project is completed before the delivery, if it is cooperated, the gas pipeline is mainly a coordination, let out the gas pipeline, the requirements for water are not very high, but there is a large spacing requirement for power wells and the like, and the gas pipeline will not be constructed after all the gas pipelines are occupied by power wells and the like. The second is the problem of the stacking site of materials and machinery. These are minor issues, though.

Gas construction has its own drawings, and you don't have to worry about this part of the design. The main thing is the pipe position in the construction and the like, because the first thing that the gas pipeline needs to ensure is safety.

Road pre-embedding before construction?? I don't know

After the installation of outdoor natural gas pipelines in the residential area and outdoor water supply and drainage, heating, fire protection and other pipelines, as well as strong and weak current pipelines, the construction of residential roads, hard pavement and greening will begin before construction. Indoor natural gas pipelines are installed after the installation of indoor doors and windows, and the installation of indoor walls is completed.

Within the scope of the urban planning of Anshun City, for the relatively remote areas, according to the "Anshun City Gas Plan" and the recent urban pipeline gas pipeline network construction plan approved by the Anshun Municipal Construction Bureau, the areas where the gas main network cannot be reached temporarily and cannot achieve gas supply in the near future shall be jointly applied by the housing construction unit and Anshun Gas Co., Ltd.

After the approval of the Anshun Municipal Construction Bureau, the installation of pipeline gas facilities can be suspended, but the urban pipeline gas facilities should be included in the housing design, and the installation location of the urban pipeline gas facilities should be reserved according to the design during the construction, otherwise the housing construction project will not be completed and accepted.

Anshun urban pipeline gas facilities construction and housing construction synchronous implementation opinions:

1. After March 1, 2008, within the scope of urban planning of Anshun City, the new construction, reconstruction and expansion of housing construction projects shall be implemented synchronously in the development and construction plots of pipeline gas facilities, so that the pipeline gas facilities and housing construction are designed, constructed and accepted synchronously, and the gas meter, water meter and electricity meter can be entered at the same time.

2. The design and construction of urban pipeline gas projects shall be undertaken by units with corresponding qualifications.

3. Within the scope of urban planning of Anshun City, urban pipeline gas facilities should be included in the review of housing construction drawings, and if there are omissions in the design of urban pipeline gas facilities in the housing construction drawings or the design of urban pipeline gas facilities does not meet the relevant specifications, the review of housing construction construction drawings shall not be passed.

4. Within the scope of urban planning of Anshun City, pipeline gas facilities should be included in the planning and design conditions of housing development and construction plots, and the housing construction unit shall go through the following procedures and obtain relevant licenses before construction.

Gas pipelines should be constructed by professionals from the gas management department in accordance with professional safety specifications, and shall not be dismantled, altered and installed without permission. When the interior decoration is done, the application will be made to the gas company before the tiling, and after the gas company accepts the application, it will reply to the user within a certain working day when it will be installed.

When installing, it is necessary to pay attention to the pipeline gas in the process of use, because insufficient combustion will produce part of the carbon monoxide gas, if the indoor air is not circulated, it is very likely to cause carbon monoxide poisoning, so when the gas pipeline is installed indoors, it is strictly forbidden to install the gas pipelines and facilities in the bathroom, study, bedroom, and other places where the air circulation is not good enough or temporary rest.

Indoor gas pipeline installation specification requirements.

1. It should be noted that the general indoor gas pipeline is installed from the underground through the wall into the room, and the non-heating area can be set up outdoors and enter the room after leaving the ground.

2. It should be noted that the pipeline is generally installed in the corridor, stairwell, kitchen or auxiliary room, and the pipeline shall not be laid indoors and underground, shall not be installed in the bedroom, shall not pass through the power distribution room, flue, air inlet duct, etc., and can be concealed when there are special requirements.

3. It is necessary to pay attention to the distance between the pipeline and the water supply and drainage, heating and hot water ** pipes and wires is not less than 5 cm, and the distance between the pipe and the distribution box, electrical switch and joint is not less than 30 cm.

4. The layout and direction of the pipeline should meet the design requirements, the pipeline shall not slope to the gas meter under any circumstances, the gas pipeline crossing the casing shall have no interface, the valve shall use a special gas valve, the back of the gas meter shall be 1 cm 2 cm from the wall, the gas meter shall be installed properly, and the inlet and outlet risers shall not be skewed.

It should be considered after the house is completely built before considering the installation of a gas pipeline. Before that, you can think about which direction the gas pipeline will come from, which room to enter, and you need to leave a hole. It is not possible to install natural gas while construction.

You go to a special place to register first, and they will inform you when to install? You just wait for someone to load the general thing, and they will be ready.

The minimum covering thickness (from the road surface to the top of the pipe) for the buried underground gas pipeline shall meet the following requirements: 1. When buried under the motor roadway, it shall not be less than; 2. When buried under non-motorized lanes (including sidewalks), it shall not be less than; 3. When buried in a place that is impossible for a motor vehicle to reach, it shall not be less than.

Legal basis: Regulations on the Administration of Urban Gas in the Blind Nuclear Project Article 11 For the construction of new areas and the transformation of old areas, gas facilities shall be built or land for the construction of gas facilities shall be reserved in accordance with urban and rural planning and gas development planning.

For the construction of gas facilities within the scope of the gas mining development plan, the competent department of urban and rural planning shall solicit the opinions of the gas management department on whether the construction of gas facilities is in line with the gas development plan when issuing the site selection opinion in accordance with the law; If it is not necessary to issue a site selection opinion, the competent department of urban and rural planning shall solicit the opinions of the gas management department on whether the construction of gas facilities is in line with the gas development plan when issuing the planning permit for construction land or rural construction planning permit in accordance with the law.

After the completion of the gas facility construction project, the construction unit shall organize the completion acceptance in accordance with the law, and within 15 days from the date of completion acceptance, the completion acceptance shall be reported to the gas management department for the record.

Hello dear, it will take about 20-30 days to complete the installation of underground natural gas pipelines; The time taken to install natural gas will vary depending on the region and the specific situation, but in general, the installation of natural gas needs to go through the following steps:1Apply:

The pipeline gas company will send staff to inspect and determine the direction of the pipeline chain and the equipment that needs to be installed. 3.Construction:

After determining the installation location, carry out pipeline laying, equipment installation and other work. 4.Detection:

After the construction is completed, the pipeline gas company will inspect the installation to ensure that it is safe and qualified. The time it takes to install natural gas can be affected by a number of factors, such as equipment selection, outdoor pipeline distance, construction environment, and more. Typically, it takes days to weeks to install natural gas, depending on the actual situation.

The following are the conditions that should be met for the opening of natural gas.

Natural gas companies generally review the "factory inspection certificate" and "warranty card" of gas cookers, and some companies also need local "temperament adaptation test report" (which should be within the inspection qualification period).

The installation unit must have qualified installation qualifications, and send personnel with installation qualification certificates for installation, and after the installation is completed, the user is required to issue a "certificate of installation acceptance".

It is recommended to consult the local gas company in detail, as the requirements of the local gas company are different.

The natural gas cooker and water heater bought online are responsible for timely after-sales maintenance.

The gas company is responsible for the natural gas, and the decoration of the community reaches a certain amount, and the property company collects the owner's ID card, room number and other information that needs to be ignited, determines the time, and notifies the waiting for ignition.

When igniting a fire, they check that the kitchen is ready for use, and if it is not available, they do not give it a fire.

The natural gas in the community is connected by the gas company to the community, and the household is in charge of the table, and the household can be used after the decoration is completed.

When will the natural gas in Liushi Town of Qingshi be used?

Pipes have been laid.

When will the natural gas in Liushi Town of Qingshi be used?

1.Whether the installation qualification of the installation project construction unit is compatible;

2.Operator's welder certificate, PE welding certificate, special machinery operation certificate (crane, etc.), plumber certificate.

According to the relevant laws and regulations of the state, the construction unit has the obligation to protect the natural gas facilities and pipelines from damage. Before carrying out the construction, the construction unit shall contact the natural gas company, and the natural gas company shall designate the natural gas line for the construction unit and sign for approval. Mechanical construction is strictly prohibited when working near natural gas pipelines to prevent natural gas pipelines from being damaged.

When the potential accident is found, the natural gas company should be immediately alarmed, and the accident will be dealt with by professionals, and the construction can only be continued after the hidden danger is eliminated.

You need to go to the Development and Reform Bureau, the Urban Construction Bureau, and the Land Bureau.

Summary. Further information: 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.).

The long-term common definition of "natural gas" 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, 2020, PetroChina Southwest Oil and Gas Field Company disclosed that the company had discovered a new zone rich in natural gas, with an estimated potential resource of more than one trillion cubic meters. 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.

The main use of natural gas is as fuel, which can make carbon black, chemicals and liquefied petroleum gas, and propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low-molecular-weight hydrocarbons and non-hydrocarbon gases.

Dear Kiss I'm glad to answer your questions <>

<> installation of the underground natural gas Qiliang pipeline will be completed in a week. It depends on the size of the project. First, an instrument is needed to quietly match the width to detect the specific location that needs to be repaired, and then it needs to be excavated after selling and cultivating, and a large excavator is generally used, but when it is close to the pipeline, it needs to be manually excavated slowly to prevent damage to the pipeline.
