January 11, 2026 – Xionggu Company learned from the Petroleum Engineering and Construction Company that the long-distance pipeline welding team for the Saudi MGS Phase III Project has set two construction records: 188 weld joints completed by a single unit in one week and 42 weld joints in a single day. Meanwhile, the one-time pass rate of weld joints has been stably maintained at over 98%, achieving outstanding performance. 

Given the heavy welding workload and stringent quality requirements of the project, the Petroleum Engineering and Construction Company implemented a comprehensive package of efficiency and quality improvement measures. It introduced three sets of fully automatic welding processes adapted to different working conditions, which significantly enhanced the standardization level of welding operations and construction efficiency. According to the relevant person in charge of Sinopec Petroleum Engineering and Construction Company, as a key component of Saudi Arabia's east-west natural gas transmission artery, the Saudi Master Gas System (MGS) Phase III Project is a core infrastructure of Saudi Arabia's energy strategy and currently the country's largest-diameter (1,422 mm) oil and gas pipeline project. Upon completion, the project will greatly optimize the local energy structure and inject strong impetus into the stable regional energy supply. As a core energy infrastructure project in Saudi Arabia, the MGS Phase III Project is also among the largest-diameter oil and gas pipeline projects under construction in the country, imposing rigorous requirements on the environmental adaptability, operational stability and quality controllability of welding equipment.

The integrated Xionggu automatic welding units are equipped with independently developed core technologies. Focusing on the complex welding requirements and addressing the welding challenges of large-diameter pipelines, these units innovatively adopt a multi-mode coordinated control algorithm and an intelligent parameter matching system, enabling precise linkage of heat input, wire feeding speed and welding torch posture during the welding process. The equipment can operate continuously and stably under harsh working conditions such as high temperature, high humidity and sandstorms, ensuring uniform external weld formation and excellent internal welding quality. 

Looking ahead, Xionggu Company will continue to deepen the research and development of core welding technologies, upgrade automated welding equipment and process solutions, and strengthen cooperation with high-quality enterprises in the industry. With more reliable products, more professional technologies and more comprehensive services, Xionggu is committed to supporting the high-quality advancement of global energy infrastructure construction and writing a new chapter for China's intelligent manufacturing on the international stage.
