Over the past few days, the Zhongsha Gulei Ethylene, Thermal Power, and Heating Pipeline Project in Fujian Province, which is being constructed by Shaanxi Huajian No.1 Company, has been making every effort to meet its delivery deadlines. The Zhongsha Gulei Ethylene Project is a major energy project resulting from cooperation between China and Saudi Arabia. Shaanxi Huajian No.1 Company was tasked with carrying out the construction work related to this project, which includes the installation of 4 steam pipelines with a total length of 5,600 meters, as well as the installation of 16-ton steel structures. The project is planned to build an ethylene plant with an annual production capacity of 1.5 million tons, as well as downstream products such as polyethylene and polycarbonate. It will utilize 19 globally leading technologies, and the products produced will be used in industries such as electronics, healthcare, and automotive. Once completed, it is expected to drive investments in related industries worth nearly 200 billion yuan. This project is an important manifestation of the alignment between the Belt and Road Initiative and Saudi Arabia’s 2030 Vision. Once operational, it will help reduce China’s reliance on imported high-end chemical products, holding significant strategic importance for ensuring energy security and stabilizing industrial chains and supply chains. As an essential \"lifeline\" for the project, this thermal pipeline network will, once completed, deliver clean, high-temperature steam produced by the second phase of Gulei Thermal Power Plant to this modern petrochemical \"giant\" on a continuous basis. The Zhongsha Gulei ethylene heat, power and pipeline project commenced on September 25. Facing a tight schedule, the project team adopted a three-dimensional construction strategy that involved making full use of space, maintaining continuous work flow, and overlapping different construction processes; welding, insulation work, and testing were carried out simultaneously to minimize the time required for transitioning between different tasks. Since the project commenced, the project team has regarded safety and quality as the lifeline of the project, actively integrating Guilei Thermal Power Company’s benchmark quality and safety management culture. By employing efficient management practices and professional skills, they ensure the quality and safety of the project construction. In light of the characteristics of high-pressure and high-temperature pipelines, specific welding procedures and quality inspection plans were developed. As of December 5, thanks to the combined efforts of the project team over a period of just over two months, 76.85% of the welding work on the 4 steam pipelines, with a total length of 5,600 meters, has been completed. Key construction processes such as civil engineering, steel structure installation, insulation work, and non-destructive testing are being carried out simultaneously, as the team makes a final push to achieve its annual goals.
