On February 8, late at night on the twenty-ninth day of the lunar month, dazzling welding lights passed through the doors and windows of the *** surfacing workshop of Zhengzhou Wanda Heavy Industry Co., Ltd., decorating the night of the New Year. At this factory, located in the Zhengzhou Airport Economic Comprehensive Experimental Zone, there are still workers who are sticking to their posts, delivering raw materials for one of China's key energy projects.
These pipes will be processed and shipped during the Spring Festival for use in the development and construction project of the Dukouhe-Qilibei gas field. Liu Songqiao, manager of the production department of Wanda Heavy Industries, told reporters that the Dukouhe-Qilibei gas field project is located in Dazhou City, Sichuan, and is a key project in Sichuan Province, with a total investment of about 5.5 billion yuan, and is expected to be fully produced in August 2024.
Dazhou is rich in natural gas reserves and is the main gas supply source of China's "Sichuan-to-East Gas Transmission" project. The construction of the above projects is of great significance for enhancing China's energy security capacity.
This gas field is the highest sulfur-containing gas field independently developed in China, although the sulfur produced can improve the guarantee capacity of China's agricultural fertilizer production, but also puts forward extremely high requirements for the corrosion resistance of mining equipment. Liu Songqiao said.
Wanda Heavy Industry Surfacing Workshop is "Henan Province Intelligent Workshop", that is, after setting the program and process, more than 10 surfacing machines will automatically operate, and nickel alloy will be plated in the cavity of pipe fittings.
The pipe wall should be coated with 3 layers of nickel alloy, and the joints and bends should often be plated with 5 to 6 layers to ensure that the pipe fittings have sufficient compression resistance and corrosion resistance. Chen Haojie, an engineer in the surfacing workshop of Wanda Heavy Industries, told reporters that most of the pipe fittings produced by the company are used in oil and gas exploitation projects, even if there are a few micron defects on the pipe wall, and the high pressure generated by tens or even hundreds of meters below the seabed and ground will directly tear the pipe fittings.
In the drilling of oil and gas wells, there is no turning back, and the slightest flaw in the pipe fittings will destroy thousands of meters of drill holes. Handheld product process quality control record card,Chen Haojie said,Although the company's products are all "big guys",But it is"embroidery kung fu"。 A pipe fitting has to go through 38 processes and three repeated inspections before and after, only the surfacing process, how much current is used in electric welding, how high the temperature of the working surface, and how to control the speed of automatic feeding, etc., are all the "unique skills" pondered by countless R&D personnel of the company.
Relying on these "unique jobs", Wanda Heavy Industry has gradually grown into one of the few special pipe fitting manufacturers in China that can carry the country's heavy equipment. The company's products are used in many major energy projects around the world, and well-known resource companies at home and abroad, such as PetroChina, Sinopec, CNOOC, Total, Shell, and Mobil, are the company's partners. "Once I watched a CCTV news report on our country's first major ultra-deepwater oil and gas development project 'Shenhai No. 1', I told my son that at least more than 100 meters of pipes used in this project were welded by your father, and my son was full of pride when he heard it. Chen Haojie said.
The Dukouhe-Qilibei gas field project has made a good start for the company's development in the Lunar Year of the Dragon. The airport area often mentions 'world-class standards, world-class', and Wanda Heavy Work will continue to move towards the vision of 'world-class pipeline manufacturer' as a resident enterprise in the area. He Qing, Secretary of the Party Committee and Chairman of Wanda Heavy Industries, said that Wanda Heavy Industries will highlight the word "precision" this year, continue to seize the highlands of various subdivisions of special pipe fittings, and use hard power to shoulder the responsibility of "the country's heavy weapon" to escort national energy security.
