Liuba to Fengxian gas pipeline project: a "network" security Sanqin

On 15 September, construction workers were welding pipes at the construction site of the natural gas pipeline project from Liuba to Fengxian.

In Liuba to Fengxian natural gas pipeline project (hereinafter referred to as Liufeng line project) construction site, the extension of the oil gas group (hereinafter referred to as the gas group) of the builders are working overtime to grab the schedule, catch up with the progress, and strive for the end of the year all line through, so that Fengxian people as soon as possible on the safety of the pipeline gas at affordable prices.


In early September, the weather is changeable, drizzle in the morning, but the sun shines brightly at noon, but this can not stop the builders continue to refresh the project progress bar. About 10 kilometres away from the county seat of Fengxian Jiudian ditch, stay in Fengxian section of the Fengxian line project construction workers are pipeline welding operations. Muddy river, a foot will be firmly sucked by the silt, difficult to step, but the site workers to overcome the difficulties, fully concentrated on the arc flashes of the weld, under the hands of the work done steadily and quickly.


"Measurement and placement is the pipeline construction 'pioneer'. Construction personnel often need to hike over the mountains, in the deep forests and grass, rugged terrain of the wilderness staking spread line, very hard." Liufeng line project Fengxian section site team leader Liu Ting said.


Stay phoenix line project in hanzhong city liuba county jiangkou town hexi village treasure han line gas pipeline trunk opening, stop in baoji city phoenix county double stone shop town ten li shop village new phoenix county end station, the line length of about 71.59 kilometres. Liufeng line project through the Qinling hinterland, involving rivers parallel and crossing 133, of which three are medium-sized rivers, but also over two large mountain ranges, through the high-speed, national highways and other arterial roads more than 10 times, is the province's 2019 newly revised Qinling ecological environment protection regulations come into force since the first excavation through the Qinling project, the construction of external constraints more, more difficult.


"The project was fired and welded on 17 December 2022, and under the unremitting efforts of all construction personnel, up to now, 45.5 kilometres of pipeline welding has been completed, and the whole line is expected to be through by the end of the year, with gas supply conditions half a year earlier than the original plan." Liu Ting said.


Shaanxi natural gas long-distance pipeline construction started in the early 1990s, after more than 30 years of considerable development, as of the end of 2022, the total mileage of the pipeline network is about 7,483 kilometres, pipeline natural gas has been covered by the province's 11 cities (districts) 88 counties (cities), LNG and CNG and other means to achieve the full coverage of natural gas in the remaining 19 counties (cities), basically formed the north-south and extend the east-west of the The natural gas transmission and distribution system is basically formed as "one network in the province". However, at present, Fengxian County is still using tanker trucks to transport natural gas, the cost of gas is higher, encountered in the rain and snow days are also prone to cut off the supply, causing inconvenience to the local people's lives. It is expected that after the opening of the project, the gas supply capacity can reach 110 million cubic metres per year in the near future, and 250 million cubic metres per year in the long term, which will end the history of Fengxian County's inaccessibility to piped natural gas, and significantly reduce the cost of gas for residents.
