The anti-corrosion steel pipe project of the Shaanxi-Beijing Fourth Gas Pipeline includes a main line and branch lines, with a total length of 1. Among them, the trunk line is Jingbian Gaoliying, passing through Shaanxi Province, Inner Mongolia Autonomous Region, Hebei Province and Beijing City, and ending at the terminal station of Gaoliying. The total length of the trunk line is about 100 million cubic meters per year. , the line cuts off the valve chamber seat, and the branch trunk line is the Gaoliying Xishatun branch trunk line. The pipe diameter is, the design capacity is 100 million cubic meters per year, and the design pressure is MPa. Set up a station seat and a line cutting valve chamber seat.
At around 1:00 am, the reporter drove to the construction site of the second bid section of Shaanxi-Beijing Line 4 in Xingwangzhuang, Tuoketuo County, Hohhot, Inner Mongolia. The workers worked selflessly in the autumn wind, inspecting the pipeline over and over again. When welding, because the diameter of the pipe is more than one meter, it is very inconvenient for workers to weld. The welding gun constantly moves on the pipe welding joint, and the welder's body torque is relatively large, making it extremely uncomfortable just to look at it. Li Shengli, head of the technical department of the consortium of Daqing Oilfield Anti-corrosion Steel Pipe Engineering Co., Ltd., said that since the diameter of the Shaanxi-Beijing Fourth Line Pipeline is 100, which is the largest natural gas transmission pipeline under construction in China, close welding procedures are required before and after each welding joint. It takes about minutes because one welder holds a pit. In order to progress the construction period, they have to work continuously every day. It is very hard to work in the wind and sand, and there is no rest time for rotation. Their crew chief Liu Feng said that no matter how hard we work, as oil people, we must inherit the Daqing spirit and the Iron Man spirit, and produce satisfactory anti-corrosion steel pipe projects, high-quality anti-corrosion steel pipe projects, and reliable anti-corrosion steel pipe projects, and strive for excellence in every process.
At around 12:00, the reporter and his party came to the construction site of the Shaanxi-Beijing Fourth Line Yellow River Crossing in Xinfa Village, Tuoketuo County. The wheels brought up sand and dust all over the sky, and visibility was almost zero. This is how our oil workers The environment is bustling with activity. Zhang Jie, the person in charge of the Yellow River directional drill crossing project of Sichuan Petroleum and Natural Gas Construction Anti-corrosion Steel Pipe Engineering Co., Ltd., told reporters that due to the relatively long span of the Yellow River flood control and ice prevention, the construction time of the Yellow River directional drill crossing anti-corrosion steel pipe project is only four months a year, and the local area The requirements for environmental protection vegetation restoration and dam flood control safety are relatively strict. They have to complete the meter-long anti-corrosion steel pipe project by the end of the month. In fact, they have less time for construction. At the same time, this directional drill penetrates up to meters underground. Due to the underground For loose sand, air expander and mud insulation technology must be used as well as a special ratio of mud. The construction difficulty of workers and the requirements for the process must be very precise.
At about 1:00 p.m., the reporter arrived at the construction site of the first bid section of the Shaanxi-Beijing Fourth Line in Suburga Town, Yijinhuoluo Banner, Ordos. Although the autumn grassland wind was very hard and cold, it could not stop the construction workers on site. enthusiasm. The reporter looked up and saw that the construction site was about ten miles away from people, with only yellow sand and grass. No matter how loud the machine roared, it could not dilute the desolation and loneliness. However, our oil workers ignored this scene and only saw in their eyes The work in hand and the responsibility and perseverance in heart. Guo Guiren, team leader of China Petroleum Pipeline Bureau, told reporters that they are mainly responsible for the construction of kilometers of pipelines in this bid section. They use the most advanced R internal welding machine in the country. Since it is a newly purchased machine, all construction personnel have a clear understanding of the equipment. Paper, all are understood and operated from scratch. For example, the connection between equipment installation and anti-corrosion steel pipe engineering is the biggest problem. Due to the excessive wind and sand, the impact on the equipment is very serious. Their workers are studying hard and trying their best to solve this problem. At the same time, they have the confidence and perseverance to complete the project with quality and quantity within the specified time. According to the reporter's understanding, the wind and sand not only have an impact on the equipment, but also on the construction workers. They keep breathing yellow sand every day, and their throats often hurt. After working for ten hours a day, they return to the station dozens of kilometers away and rush to the hospital. Take a bath because their bodies and faces are covered with yellow sand.
On the day of March, the reporter and his party arrived at the preliminary construction site of the Chahar right wing of the third tender section of the Fourth Line of Shaanxi-Beijing. On the solstice, the reporter visited Yanjiafang, Jimingyi Town, Xiahuayuan District, Jimingyi Town, of the fourth section of the Fourth Line of Shaanxi-Beijing. At the construction site of Yanjiabao Village and Huijiatun Town, Huai'an, oilmen were burning with passion and releasing energy in the autumn rain.
The coming winter will be happy for Inner Mongolia, Hebei, Beijing and Tianjin. Because before the coldest month arrives, the fourth line of Shaanxi-Beijing will be fully connected, thus ensuring the safety of gas supply to the four provinces and two cities together with the first line of Shaanxi-Beijing, the second line of Shaanxi-Beijing, and the third line of Shaanxi-Beijing.
But this winter has been hard for pipeline builders. In order to ensure that the entire line is connected by the end of the year and meet the peak winter gas consumption in Beijing and along the pipeline in the coming month, pipeline builders are fighting against the wind, sand, and severe cold on deserts, grasslands, rivers, hills, and mountains, and are racing against time to fight on the front line of construction.
