Chu Kong Steel Pipe Awarded Guangdong Provincial Advanced Collective

As the only Chinese enterprise to successfully develop and manufacture 3,500-meter-class ultra-deep-sea oil and gas transmission pipelines, Chu Kong Steel Pipe’s R&D team has spent years tackling core technologies such as deep-sea pipeline steel smelting, high-precision forming, and non-destructive testing. With 8 patents awarded and 4 national standards led, the team has broken through technological monopolies by Western countries, making China one of the few nations globally to master ultra-deep-sea pipeline manufacturing. Their achievements have been applied in key domestic gas fields such as Enping and Yacheng, as well as international projects like Nigeria’s offshore oil and gas pipeline engineering, connecting deep seas and lands, and linking domestic and global markets with "flawless" Chinese steel pipes.

From the 2.8-ton drop weight test simulating impact resistance in the laboratory to the "sharp-eyed" intelligent detection on the production line, this team—core members including doctors and senior engineers—has consistently deepened its expertise with the spirit of a "deep-sea dragon." They not only solved the technical puzzle of high-efficiency welding for medium-carbon thick-walled steel pipes, increasing production efficiency by over 10 times, but also developed cutting-edge products such as heat-resistant alloy steel pipes and ultra-high-pressure CO₂ steel pipes, enabling "Made in China" to stand firm in extreme environments.

Behind this honor lies robust strength: In 2024, Chu Kong Steel Pipe achieved an operating revenue of 2.94 billion RMB (a year-on-year growth of 10.9%), net profit of 213 million RMB (a year-on-year growth of 15.7%), and overseas sales soared to 2.219 billion RMB (a year-on-year growth of 61.9%). Products are exported to over 80 countries and regions worldwide, from energy pipelines in Africa to cross-sea bridges in Southeast Asia, making "Chinese-made" steel pipes a reliable choice in the global infrastructure sector. An annual R&D investment of 127 million RMB further demonstrates the company’s commitment to innovation-driven development, ensuring every meter of steel pipe embodies the craftsmanship and responsibility of "forging the deep blue."

This honor marks a milestone in thirty years of dedicated work and serves as a new starting point. Chu Kong Steel Pipe will continue to leverage the momentum of this advanced collective, extending deep-sea technologies to more global projects, connecting the world with high-quality products, and writing more "deep blue legends" with Chinese ingenuity.
