Founded in August 2002, Shandong Longquan Pipeline Engineering Co., Ltd. is a leading business in the production of prestressed concrete cylinder pipes (PCCP) in China’s building industry. Our head office is located in Boshan Economic Development Area, Zibo, Shandong. On April 26, 2012, our company was listed as Share A among small and medium enterprises in Shenzhen Stock Exchange (name of security: Longquan stock; security code: 002671). Presently Longqian has obtained many titles, such as vice president unit of China Concrete and Cement Association (CCPA), vice president unit of Chinese Cankerous and Protection Society, vice president unit of Shandong Silicate Society, one of the organizations that involve in drafting the national and industrial standard on PCCP, and member unit of Research on Major Issues before the 13th Five Year Plan of China’s Building Material Industry. Our company has a provincial enterprise technical center and is rated as Shandong Research Center on PCCP Engineering. We have also set up the Longquan Research Institute on New Material Engineering and Technology with Beijing University of Technology, which is aimed at the design and research of PCCP featuring long service life, corrosion resistance and long efficiency. Now our company has obtained 61 patents for invention and utility model patents related to production, research and anticorrosion of PCCP.

　　Following the development concept of “market comes before factory” and “solid efforts lead to a large business; intelligence brings about prosperity”, our company takes the lead in advancing and effectively applying the innovative business model featuring “establishing factory in other cities as well as flow production” and has set the Build a time-honored enterprise in Longquan, and realize the sales revenue of RMB 10 billion.
