Hanjian Pipe Industry developed and produced PCCP pipes with an internal diameter of 4 meters, which filled the nation’s technical gap. Hanjian Pipe Industry has successively undertaken many well-known domestic water conservancy projects across half of China, such as the Beijing section of the South-to-North Water Diversion Project, the Shanxi Wanjiazhai Yellow River Diversion Phase II, and the North Hubei Water Resources Allocation Project.
In June 2015, Hanjian Pipe Industry was listed publicly on the Shanghai Stock Exchange. Relying on innovation and the capital platform, Hanjian Pipe Industry developed the core technologies of underground integrated pipe galleries, sponge cities and three-dimensional automobile garages. It also acquired Hezhong Building Materials Co., Ltd. and Qingqing Environmental Protection Co., Ltd, in order to extend its business to the concrete admixture industry and the environmental protection, with a future goal of becoming a general contractor and operator of urban infrastructure construction projects.
