As the first company in China’s water conservancy sector to achieve mass production of ceramic-coated piston rods, Wujin Hydraulic built the country’s first long-stroke ceramic piston rod production line in 2007. In 2013, the company took the lead in drafting the energy industry standard NB/T 35017-2013 Technical Specification for Ceramic Coated Piston Rods, which was promulgated by the National Energy Administration of China. Today, this standard remains a benchmark for the industry, reflecting Wujin Hydraulic’s leading expertise and technological innovation in ceramic-coated piston rod technology.
