Recently, the steel structure project of Section A of China Coal Yongcheng 2×1000MW High-efficiency Ultra-supercritical Unit Project, in which Hualing Heavy Industry participated in the construction, has been successfully completed, achieving the established construction goals. As the primary manufacturer of steel structures for this section, our company undertook the fabrication and supporting works for key components including pipe rack structures, steel coal hoppers, flue duct support steel structures and color plate enclosure. With professional contracting capabilities, we have provided solid support for the construction of this national key power project.

The China Coal Yongcheng 2×1000MW High-efficiency Ultra-supercritical Unit Project is a key project for regional power supply security. Adopting high-efficiency ultra-supercritical technology, the units feature outstanding advantages of low coal consumption, low emissions and high efficiency. It is of great significance for optimizing the regional energy mix and ensuring stable power supply. Extremely high requirements are placed on the design precision, fabrication quality and installation performance of the steel structures.As the load-bearing passage for the power plant’s process pipelines, the pipe rack steel structure runs through the main powerhouse area, featuring a large number of components and complex joint configurations. Adopting factory prefabrication and modular supply mode, our company carries out strict inspections before delivery. The efficient and precise on-site assembly effectively shortens the construction period and ensures on-time delivery. During fabrication, welding procedure qualification and non-destructive testing are strictly implemented to guarantee the safety and reliability of every weld joint.

The flue duct support steel structure serves as a critical guarantee for the safe operation of the units. Combined with mechanical load characteristics, our company optimizes the structural design. Every link from material selection and welding to anti-corrosion coating is strictly controlled to ensure long-term structural stability. The enclosure presents a smooth and aesthetic appearance, winning praises from all parties on site.The successful completion of the China Coal Yongcheng Project demonstrates Hualing Heavy Industry’s manufacturing strength and service capacity in the field of large-scale power steel structures. Going forward, adhering to the business philosophy of "Quality First, On-time Delivery, Comprehensive Service", the company will continue to deepen its presence in energy infrastructure. With elaborately crafted steel structure products, we contribute to the development of China’s new power system.
