Yandang Secures Flagship Contract with Wanhua Chemical for Complex Anti-Corrosion Network

In 2019, the Yandang brand​ was selected to fully retrofit the critical fluid pipe network at Wanhua Chemical, a national benchmark in the fine chemical industry. The project demanded extreme resistance to aggressive acids, alkalis, and organic solvents—conditions where standard piping fails.

The Challenge​

Wanhua Chemical’s complex production environment involves highly corrosive media and intricate process networks. Any pipeline solution had to ensure absolute safety, structural integrity, and long-term stability​ across multiple scenarios, including process fluid transfer, circulating water systems, and wastewater transport.
