The renewal of the city -burning pipeline of Xiyuanyou

Text/Lu Miao Xu Bo

After decades of development, my country's urban gas industry has entered a stage of aging network and increased hidden dangers. The gas explosion accidents occurred in Hubei Shiyan, Handan, Hebei, and Shenyang, Liaoning, and continued to sound a safety alarm bell. It is urgent to accelerate the renovation of old gas pipelines.

On June 10, the "Notice on Printing and Distributing the Implementation Plan for the Renewable Update and Reconstruction of Urban Gas Pipelines (2022-2025)" (hereinafter referred to as the "Implementation Plan") will undoubtedly promote the update and transformation of old gas pipelines and improve urban gas gas The safety factor of the pipeline. However, the author believes that the "Implementation Plan" is mixed for urban gas companies.

Policy support

In the author's memory, the "Implementation Plan" is the first time that the State Council has been issued by the State Council to the urban gas industry in the past 12 years. The previous time was the "Regulations on the Management of Gas Management" adopted by the 129th Executive Meeting of the State Council on October 19, 2010. It can be seen that the "Implementation Plan" is not light.

It is restricted by many factors, the transformation of the old pipeline network has always been a headache for urban gas companies. The central government attaches great importance to this work, which is undoubtedly given greater support for enterprises. It will inevitably promote enterprises to accelerate the elimination of gas safety hazards, stimulate the enthusiasm of enterprises to implement the renovation of old pipeline networks, and enhance the level of gas facilities.

The transformation object involved in the "Implementation Plan", in addition to the underground pipeline, riser, factory stations and user facilities, etc., it is believed that the "other high -risk pipelines such as constructing the construction of the constructed plant" should be included in the transformation.

The pipeline occupation has always been a "boss difficulty" problem, and it is difficult to implement the transformation. Especially in recent years, the rate of urbanization has increased, and a large number of post -building buildings occupy the original pipeline. Once the building on the pipeline is completed, it is not easy to remove it. If the pressure of the "Implementation Plan" is made up, the local government is determined to promote it, which must be a gospel for urban gas companies.

The "Implementation Plan" mentioned that "the owners have pipelines and facilities for gas such as gas, and they can be transferred to professional operating units after updating and transformation, and they are responsible for subsequent operation, maintenance, and renewal." In the past, the property rights of the owner's exclusive part of the gas facility belonged to the owner, but in accordance with the provisions of the "Urban Gas Management Regulations", the liability of the gas enterprise assumed the renovation and transformation. The "Implementation Plan" stipulates that this part of the pipeline is transferred to urban gas enterprises. Although the enterprise has increased responsibilities, it has a certain rationality from the operation management of facilities, and realizes the unity of the ownership and maintenance responsibilities of pipeline facilities.

It is worth mentioning that the "Implementation Plan" mentioned that the relevant investment costs will be included in the cost supervision, and the relevant cost costs are included in the price cost. Therefore, the investment of enterprises will form an effective asset. Even if it maintains a fixed rate of return, the income of the enterprise will increase, which is undoubtedly beneficial for urban gas companies.

Worry about investment pressure

According to the "Supplementary Notice on Declarating the Application of Aging Update of Urban Gas Pipelines and other aging renewal and renewal in the 2022 Central Budget Investment Plan", "the scope of investment support in the central budget includes the gas riser, courtyard pipelines and courtyard pipelines shared by residents in the building area. The aging of facilities is updated, the residents replace the gas rubber hose in the household, and the gas safety devices that need to be installed. The aging update and transformation of urban gas pipelines of industrial and commercial users. "

This shows that the investment subsidy in the central budget is targeted at the assets of pipeline facilities shared by the government or residents. At the same time, the "Implementation Plan" requires that "professional operating units must fulfill the responsibility for aging renewal and transformation of aging renewal and transformation of gas pipelines within the scope of their services."

According to the calculation of the national authoritative authorities, the renovation cost of the old pipeline network is about 500,000 yuan/kilometer, and it will invest 50 billion yuan in 4 years. Entering exceeding 10 billion yuan each year, this is by no means a small number for the urban gas industry, let alone the difficulty of the urban gas enterprise this year's price increase, and the difficulty of getting money to transform the old pipeline network is quite difficult.

In addition, for the factory stations and facilities involved in the reconstruction project, because the main operating areas of urban gas companies are generally urban areas, they are restricted by land planning. Standard venue. This part of the transformation is also difficult.

In the long run, the scale and professional development of urban gas enterprises are the general trend. The "Implementation Plan" proposes that "supporting the merger and reorganization of industries such as gas, ensuring the completion of aging renewal and reconstruction tasks, and promoting the scale and professional development of the gas market." Recently, Zhejiang, Guangdong, and Shaanxi have clearly stated that it is necessary to regional integration of urban gas. It is not difficult to see that the government's policy orientation for industry integration is very clear. A large number of small and medium -sized gas companies that lack large -scale, specialized, and constant accidents have not been considered to leave the problem.

Must be carefully implemented

The "Implementation Plan" is the highest guidance document for the transformation of facilities such as old pipe networks such as old pipeline networks in the urban gas industry in the next three years. Enterprises will undoubtedly implement them seriously. I suggest:

First, continue to increase the investigation of hidden dangers. Focusing on the completeness of the system and the effectiveness of the system and the effectiveness of the system, the implementation of the implementation of the gas enterprise system system is carried out. Carry out the safety investigation and rectification of the gas construction process around the legal conditions of the construction process and the safety management of the construction process. Carry out the management of gas supply safety inspection and rectification around the operation management management management management management management management management management management management and the hidden dangers of the pipe network equipment and facilities. Focusing on the safety of gas use of non -residents and residents, the safety inspection and rectification of gas use is carried out. Focusing on employee safety education, training employee professional skills and popularization of gas safety, training and publicity effects are carried out. Secondly, improve the level of science and technology. Gas safety depends on private defense, but also depends on technical defense. The use of information and digital technology to accelerate the establishment and improvement of gas perception system should become one of the key tasks of urban gas enterprises in this pipeline network transformation.

For example, in terms of safety monitoring of the gas pipe network, you can use the existing "Snow Light Project" video and supplement some probes, adopt AI identification technology, monitor the construction behavior of the access to pipeline, and call the police in a timely manner. For the legal construction operations around the pipeline, the monitoring of the intelligent electronic industry piles is deployed to prevent the construction of the construction of the gas pipeline. Strengthen the user -side gas leak detection alarm. Due to technology and cost, user -side gas leakage detection is a weak link. In the non -residential user side, in accordance with the relevant requirements of the "Safety Production Law of the People's Republic of China", the gas leakage detector can be installed; on the residential user side, it is encouraged to install gas leakage alarm devices.

Finally, we will further strive for more support from relevant government departments. It is recommended that local governments establish a green channel for approval of the gas renovation project of old urban and towns, and adopt the methods of informing the commitment, establishing an exemption list, and decentralizing approval authority to simplify the approval and completion acceptance procedures for the approval and completion acceptance of fiscal review, bidding, fire protection, civil air defense, and construction. It is recommended that the gas authorities of all places summarize the experience of old communities that have been implemented in the renovation of gas facilities, and extensively solicit opinions from design, construction, and construction. Users are essentially safe. For old communities with technical difficulties, it is recommended to optimize the design plan for gas enterprises to organize design units. After passing by experts, they are reported to the relevant government departments to confirm to implement it.
