Company
Shanghai Hongsheng Special Valve Manufacturing Co., Ltd. was established through the restructuring of the former Shanghai Marine Valve Factory (established in 1981). In 1997, the main departments of technology, production, and operation of the former Shanghai Marine Valve Factory were reorganized according to the requirements of modern enterprises on the basis of all laid-off employees of the original enterprise, and formed this enterprise. Our company currently has 16 engineering and technical personnel, with the goal of developing and updating products, constantly adapting to market demand, and filling market gaps, abandoning the previous large and comprehensive, diverse production model. For many years, we have been committed to the development and production of large-diameter, high-pressure, and high-temperature resistant ball valves, achieving good social and economic benefits. The large-diameter high-pressure explosion-proof and anti burn ball valves produced have been certified by industry experts, filling the gap in China. The company completed the ISO9001 (DNV certification) quality certification work in September 2000< br>
The enterprise obtained the Special Equipment Manufacturing License in 2004< br>
Over the years, our company's large-diameter high-pressure valves have gained a good market in the oil and gas industry. We have successfully participated in projects such as the Zhongji natural gas pipeline, the Luning oil pipeline renovation, the Huangdao oil depot of CPC, and the Shanghai natural gas transmission and distribution, accumulating experience for better participation in petroleum, petrochemical, and natural gas construction in the future< br>
Since 1992, our company has been involved in the development of valves for coal gasification projects at Lunan Fertilizer Plant, Buhai Coking Plant, and Huainan Fertilizer Plant. Over the past decade, we have explored and improved the localization of grey black water and slag water valves. In 2003, we participated in the large-scale fertilizer transformation project of Shandong Dezhou Hualuheng Chemical Co., Ltd. and undertook a special project of the National Development and Reform Commission. At the same time, our company's hard sealed ball valve was installed at Jinling Petrochemical; Nanhua Phase I and II; Yankuang Guohong Chemical, Heilongjiang Haolianghe Fertilizer Plant, Shaanxi Shenmu Chemical, Shanxi Fengxi Chemical, Inner Mongolia Sanwei and other coal gasification projects have been widely used. The company has made efforts to research and develop coalification ball valves, forming four major varieties: lock bucket valves, switch valves, molecular sieve cut-off ball valves, and manual cut-off pipeline valves for black grey water, with more than ten series and hundreds of specifications. Since 2005, slag locking valves have been used in companies such as Hualu Hengsheng Chemical and Shanxi Fengxi Chemical, and have received positive feedback.
The company is located at 368 Jinbai Road, Jinshan Industrial Park, a first-class industrial park in Shanghai. The company covers an area of more than 40 acres and has a factory area of over 20000 square meters.
