Xishan Gujiao 202 15 households used natural gas during the year.

Natural gas replacement project is a practical project and livelihood project promised by Gujiao Municipal Government to the people of the whole city, and it is currently being implemented. According to the current progress, 202 15 households in Gujiao will use natural gas during the year, and the number of households using natural gas in the old city of Gujiao will exceed15,000 households.

Make a comprehensive plan and lay a solid foundation.

Natural gas replacement is a highly technical work with high safety requirements. Therefore, according to the principles of "safety first, safety first" and "easy before difficult, easy after difficult", Gujiao Municipal Government has made a clear understanding of the base, improved the system, and laid a good technical foundation for the implementation of natural gas replacement.

It is understood that the urban gas supply and management of Gujiao City belong to two units, and Gujiao Gas Thermal Power Company is responsible for the gas operation management of the old city; The gas source plant and pipe network of Xishan Coal Gasification Company are responsible for gas production and gas operation management in residential areas of resident units.

In 2065438+2007, an investment of 650,000 yuan was made, and the inspection agency was entrusted to inspect and investigate the pressure regulating stations, medium and low pressure pipelines and users under the jurisdiction of the coal thermal company, as shown in the above figure. Xishan Pipe Network Institute also conducted a thorough investigation, thus forming the current situation map and working schematic diagram of the city's natural gas replacement project, which laid the foundation for more intuitive and accurate implementation of natural gas replacement work.

From 2065438 to 2008, 440,000 yuan was invested to detect the damage degree, ion loss degree, gas leakage and blockage of the 68km medium and low pressure pipeline within the jurisdiction of Coal Thermal Company, which was completed in early June, providing a scientific basis for the transformation of the old pipeline network. Invested 300,000 yuan, entrusted the safety management organization to establish a complete safety management system, initially formulated a manual of technical specifications for natural gas replacement, and began to train the staff, gradually clarifying the posts, responsibilities, processes and specifications of natural gas replacement staff.

Eight projects are slowly but surely.

At present, the gas distribution station, medium pressure pipe network and medium pressure pipe network of China New Energy Replacement Natural Gas Company have met the requirements. Eight projects involving the replacement of natural gas, some have been completed, and some are progressing steadily.

1. Laying Project of Dachuan River 1.7km DN200 Gas Medium Pressure Pipeline (Nanping Street-Fukang Fan Bridge). The project has been completed and the pipeline has passed the test, with an investment of nearly 3 million yuan.

Secondly, there are 22 interfaces between the pressure regulating station and the medium pressure pipeline. The project bidding has been completed, and the municipal, road and other departments involved and the relevant underground pipeline property rights units are being coordinated to handle related matters. Construction will start in the near future, and it is expected to be completed in about 10 days.

The third is the reconstruction project of the old pipe network in the hospital. 20 14 replaced 5690 meters, and 20 17 to 20 18 replaced 5500 meters at the end of June. In 20 18 years, according to the report of the inspection organization and the inspection results of the line patrol personnel, 49 leaked pipelines were repaired and replaced 1 100 meters, with an investment of 360,000 yuan; It is planned to replace the old pipeline of10210m, and the plan has been made, and the budget list and expenses are being prepared.

Four, the new pressure regulating station and pipe network project in the eastern new city. It is planned to lay 2280 meters of medium and low pressure gas branch lines in the new volcanic area, and build 7 new pressure regulating stations in the new volcanic area and Hekou area. The project has been approved, the design has been completed, and the budget list and expenses are being compiled.

Fifth, the renovation project of 29 pressure regulating stations. The bidding work has been completed and will be started as soon as possible.

Sixth, the remote monitoring system project of voltage regulating station. It is planned to install a safety explosion-proof, over-voltage and under-voltage alarm monitoring system at each pressure regulating station, so as to find problems in time and realize remote control. At present, the design has been completed, and the budget list and expenses are being compiled.

Seventh, replace the infrared gas meter project. The bidding for 2017,4760 watches has been completed, and the procurement has not yet been put in place; 20 10000, it is planned to replace1000m, and spare1000m. At present, the project has been established, and the budget list and expenses are being compiled.

Eighth, the renovation project of indoor gas facilities for users. It is planned to renovate some indoor facilities in urban areas 107 18, which are not suitable for natural gas conversion. The indoor front valve, rear valve and riser plug valve will be replaced by stainless steel bellows, the rear valve will be replaced by self-closing valve, and the front valve plug valve will be replaced by gas-specific ball valve. The project has been approved, and the budget list and cost are being prepared.

Carefully organized and completed with high quality.

At present, the natural gas replacement work is progressing steadily and solidly. The relevant units will specifically organize the household inspection before replacing natural gas with coke oven gas, the personnel deployment, emergency preparation, pipeline inspection and gas household monitoring during the replacement process, and the leak detection and return visit of the pipe network after entering the household to ensure safe replacement, sum up experience and solidly and steadily promote the specific work of natural gas replacement.
