Welding of the process pipelines for the main equipment at Anyue No. 2 Purification Plant is completed

Thread Content

On July 30, an important milestone was reached in the construction of the Anyue No. 2 Natural Gas Processing Plant of Southwest Oil and Gas Field Company (referred to as Anyue No. 2 Processing Plant): the welding of the process pipelines for the main units in Column I was completed entirely. This natural gas processing plant, with a daily processing capacity of 12 million cubic meters and built by CNPC Southwest Oil and Gas Field Company, has taken a crucial step toward achieving operation by the end of September this year. In the face of challenges such as high temperatures, frequent rainfall, and complex operating conditions, the project team strengthened overall planning, focused its efforts precisely, and steadily advanced the high-quality construction of the project. Innovative management models. The project team innovatively adopted a \"grid-based + digital\" management approach, dividing the construction area into 15 responsibility zones to achieve precise control. Establish a quality control system and create a four-tiered coordination mechanism comprising the \"Construction Project Department + Supervision and Manufacturing Oversight + Installation Quality Inspection + Third-party Quality Random Checks\", in order to effectively ensure the quality of the actual construction work and achieve comprehensive random inspections of on-site construction quality. Ensure quality in key areas. The team develops assessment plans for welders’ eligibility, aiming to create a high-standard welder workforce. Third parties are brought in to conduct physical quality inspections of key materials, in order to objectively assess the quality of the project. In terms of quality management, a \"three-level control\" system was introduced to ensure oversight at every stage, from the verification of welders’ qualifications to quality tracking; as a result, the welding qualification rate reached 97.5%, which is higher than the industry standard. Strictly control the material acceptance process. The project also ensures construction safety and quality through real-time monitoring via an intelligent platform. A three-level quality control system of \"manufacturer monitoring,\" \"professional supervision,\" and \"additional inspections through unannounced audits\" has been established, with six regions designated for regular on-site inspections of various materials. A verification method of \"two strictnesses, three correspondences, and four non-acceptances\" is applied to the equipment and materials upon arrival, ensuring a 100% acceptance rate for such items. In the face of the persistent high temperatures this summer, the project team adjusted working hours scientifically, provided front-line workers with intelligent cooling equipment, and set up temporary rest areas to ensure both the progress of construction and the health of the workers. During the peak period of the project, over 250 welders were employed to complete 35.8 million welding tasks, setting a new record for projects of this type. The successful progress of this project not only supports SSWEC’s strategy to achieve 50 billion cubic meters in production but also accumulates valuable experience in the construction of large-scale purification plants. Upon completion, the project will further enhance the natural gas purification capacity in the Sichuan-Chongqing region, providing a solid foundation for regional energy supply.
