Xinjiang News, February 3 (Tian Yu, Guo Ziyi, Yang Wenjuan, Pilates) Affected by a new round of strong cold air, the cold wave is coming, Hami has ushered in a new round of cooling temperatures, and the supply of natural gas has gradually risen. In the face of the multiple tests of cold wave, rain and snow, safe operation and stable supply, the front-line workers of the Xinjiang Oil and Gas Transmission Branch of the Western Pipeline Company of the State Pipeline Network Group stuck to their posts 24 hours a day, and in the "main battlefield" of natural gas supply in winter, behind the warm and peaceful lights of thousands of homes, they became "guardians", fearless of the severe cold of winter, and made every effort to ensure the safety and stability of natural gas in the city.
Yang Erwei, after graduating from Henan Polytechnic University in 2022, came to work at the Hami distribution station, and his and his colleagues were tasked with inspecting the equipment in the distribution station every day to ensure the stable operation of the equipment. In order to ensure the safety of the equipment in the station, Yang Erwei and his colleagues adopted a combination of on-site monitoring and manual work to ensure that thousands of equipment were inspected in place 100%. The wind and snow were unhindered, and they did not slow down the pace of inspection.
Yang Erwei, an electrical operator in the Hami Pier operation area of the Xinjiang Oil and Gas Transmission Branch of the Western Pipeline Network Group of the State Pipeline Network Group, said: "This year is the first Lunar New Year since the expansion of our distribution station, and the test of winter supply is more severe. We have carried out a systematic maintenance of the equipment on site, and at the same time, we have simulated and rehearsed the response measures for various abnormal situations, sorted out the existing emergency supplies, supplemented a batch of electric heat tracing, regulating valves, steam trolleys, etc., to ensure that when abnormal situations occur, we can deal with them in the first time, although our equipment automation has been very high, but we will still check the equipment on the site at ten o'clock in the morning and evening every day to ensure that the equipment is more stable and can not make the slightest mistake. Especially during the current winter supply guarantee period, we will conduct an encrypted inspection of the on-site parameters at four o'clock in the morning, when the weather is the coldest to ensure that problems can be found and solved during the winter supply guarantee period to ensure the normal operation of natural gas.
In order to improve the gas source structure of Hami and solve the gas demand of downstream gas companies, the Xinjiang Branch of the Western Pipeline will officially invest in the construction of the new first-class project of the Hami natural gas distribution station in 2023. **After the point is successfully put into operation, the annual designed distribution capacity of Hami distribution station will reach 203.5 billion cubic meters, compared with the original 1800 million cubic meters, an 11-fold increase. Coming out of the station control room, Yang Erwei and his colleagues came to the process area where the air flow roared, and they wore red anti-static suits to comprehensively investigate the potential safety hazards of the station equipment.
Yang Erwei, an electrical operator in the Hami Liodun operation area of the Xinjiang Oil and Gas Transmission Branch of the Western Pipeline Company of the State Pipeline Network Group, said: "I see this equipment in your hand, what is the purpose of this?" This is called a four-in-one detector, which is mainly used to test our natural gas pipelines, if the interface is located in which place, etc., if it is not tightly fastened, there will be natural gas leakage, and we use it to detect the concentration of natural gas, on the one hand, it is to ensure the safety of our pipelines, on the other hand, it is also to ensure the safety of our station and downstream gas supply. ”
The Hami distribution station mainly distributes the gas from the second line of the West-East Gas Transmission Line to the Hami Xinjie Gas Gate Station, the Hami Hongtong Gas Erdaohu Industrial Park Gate Station, the CNG mother station, and the LNG reserve peak shaving plant, etc., to provide a reliable, stable and clean gas source. With the rapid growth of gas supply, the test of equipment is increasing, Yang Erwei and his colleagues closely focus on the smooth operation of the station, strengthen on-site management, and effectively deal with the smooth operation of natural gas under special weather conditions.
Now it's the on-site electric valve failure, you can confirm it on the spot. "Roger. Yang Erwei said: "In early winter, the temperature is particularly low, which can reach nearly minus 20 degrees, or even about 30 degrees, because we have added the first point this year to supply gas to downstream users, and their equipment has failed, which will affect the operation of our on-site equipment, we will switch the automatic analysis logic to manual distribution, and our employees will come to the site to adjust the valve on the spot, at four or five o'clock in the morning, we will adjust the site, and insist on the downstream manufacturers. Only by restoring their equipment did we restore the normal operation of our field equipment, that is, we restored our automatic distribution logic, so as to ensure the normal gas consumption of downstream users and the best energy.
Due to the peak period of gas consumption of various users during the Spring Festival, Yang Erwei and his colleagues used scientific and technological means to empower safe production, regularly discharged sewage from filters, pressure gauges and other equipment and facilities, checked the operation status of equipment, etc., to prevent freezing or blockage caused by cold weather, so as to achieve early detection, early treatment, and early resolution. At the same time, by shortening the inspection cycle, increasing the frequency of inspection, strengthening inspection methods, etc., the potential safety hazards are timely improved, so as to ensure the normal operation of pipelines and equipment in low temperature weather, and ensure the production and living gas. Xu Shuai, deputy director of the Hami Liodun operation area of the Xinjiang Oil and Gas Transmission Branch of the Western Pipeline Company of the State Pipeline Network Group, said: "After our new ** point is put into operation, we have effectively guaranteed the natural gas in the Hami area, and in 2023, the natural gas of the Hami distribution station will be 35.9 billion cubic meters, an increase of 24.9 billion cubic meters, of which our new Hami Hongtong and Xinjie new gas supply increased by 24.4 billion cubic meters, and now we distribute more than 3 million cubic meters of natural gas every day, which is 10 times that of before. ”
On duty that day, Yang Erwei and his colleagues in the pier operation area spent time in a busy situation, completing the inspection and maintenance of more than 800 kilometers of gas pipelines and more than 2,000 pieces of equipment, and dealing with 4 problems of various kinds. This Spring Festival is also the first Spring Festival he spent on the post, so that every equipment and facilities are in a healthy state, and the entire pipe network is in a safe operating state, which has become his biggest responsibility.
Yang Erwei, an electrical worker in the Hami Lidun operation area of the Xinjiang Oil and Gas Transmission Branch of the Western Pipeline Company of the State Pipeline Network Group, said: "The Spring Festival is coming, and in this day of reunion of thousands of families, we can see everyone using clean natural gas, sitting in a warm home, full of laughter, we feel that all the efforts and perseverance are worth it." ”
