Corrugated expansion joints are widely used in long-distance water diversion projects. As a key supporting component of pipeline systems, corrugated expansion joints play an important role in absorbing thermal expansion and contraction of pipelines, relieving stress caused by geological settlement, and compensating for pipeline displacement. They directly affect the safety, stability, and service life of water transmission projects. Our company has been deeply involved in the water conservancy industry for many years, and has participated in 172 major national water conservancy projects such as the Yunnan Central Water Diversion Project, the Hubei North Water Resource Allocation Project, the Shaanxi Hanji Wei Water Diversion Project, the Inner Mongolia Nao Ji Liao Phase II Project, the Qinghai Daji Huang Water Diversion Project, the Xinjiang Santanghu Naomao Lake Water Supply Project, and the Xinjiang Zhundong Water Supply Phase I Project.

Our company specializes in providing a comprehensive range of valve products for the water conservancy industry, including gate valves, butterfly valves, and flow/pressure regulating valves. These products are widely applied in water conservancy projects, water conveyance trunk lines, and pipeline networks, delivering stable and reliable fluid control solutions for the sector. The company has participated in numerous domestic and international water conservancy valve projects, including: Fujian Pingtan and Minjiangkou Water Resources Supporting Project, Pakistan Karot Hydropower Station Ecological Water Release Project, Philippines WAWA Pumped Storage Power Station, and Pakistan Karot Hydropower Station.
