Radial-Axial Rolling, Weldless Integrated Forging
We manufacture transition sections using the internationally advanced "forging-rolling" (free forging + radial-axial rolling) process, and we are one of the few manufacturers in the world to master this technology.
Compared with the traditional "free forging" process, the "forging-rolling" technology offers faster delivery, better performance, more flexible dimensions, and higher cost-effectiveness.
"weldless integrated forging" technology in the production of large-scale refining and chemical equipment transition sections have also provided a powerful reference case for the future design concepts of such equipment.
Dual Production Line Synergy for Rapid Delivery others
We have two transition section production lines: a 13,500-ton press line with a diameter of 16 meters and a height of 3 meters, and a 22,000-ton press line with a diameter of 22 meters and a height of 5 meters, enabling mass production of large transition sections.
In-House Smelting Equipment, More Controllable Material Composition
Core component materials critically determine performance characteristics, while large ingot material utilization significantly impacts cost structures. In partnership with Academicians Li Yiyi and Li Dianzhong from the Chinese Academy of Sciences, we offer both conventional custom ingots and innovative metal construction formed ingots - a groundbreaking technology achieving over 95% material utilization.
