Sponsored by the National Energy Board, "Natural Gas Pipeline localization of key equipment development work to start and Signing Ceremony" recently held at Beijing's Diaoyutai State Guesthouse, Shanghai NELES JAMESBURY gas Valve Co., Ltd. as the key to long-distance pipeline equipment at home full-welded large-diameter high-pressure valve in the development of one of the units, was invited to attend this meeting. Shanghai NELES JAMESBURY valve, general manager Mr. Li Zhongguang officially in the "Natural Gas Pipeline localization of key equipment for large-diameter welded high-pressure valve in the development of contract" to sign it. In this signing ceremony, the National Energy Bureau, China National Petroleum Corporation and China Machinery Industry Federation organized a great deal of research and study, eventually Valve Co., Ltd. Shanghai NELES-JAMESBURY Company stand out from the numerous valves become a high-pressure large-diameter welded ball valve, one of the designated manufacturers. Signing ceremony in this state for the first time as a high-pressure large-diameter valves, one of major equipment, reflecting the large-diameter high-pressure valves to accelerate the pace of domestic production as soon as possible to break the monopoly of foreign determination and confidence. The parties signed a contract to use the oil to China West-East Gas Pipeline Company, the witnesses for the State Energy Bureau, China National Petroleum Corporation and China Machinery Industry Federation and other units. Signing the contract requirements Shanghai NELES JAMESBURY Valve Co., Ltd. in April 2010 before the developed to adapt to on the ground installation (with electric actuator) and the underground installation (gas-liquid interaction with implementing agencies, with a plus pole ) of the three specifications, two types of high-pressure-driven large-diameter welded ball valve. The company said it will strictly follow the "high-pressure large-diameter welded ball valve made of trial and technical conditions" requirements, develop a comprehensive design and production plans to ensure production of high-quality products, and by the China National Petroleum Corporation and China Machinery Industry Federation, organizations, experts, acceptance, sent to the China National Petroleum Corporation West-East second-tier industrial designated test site, in order to make new contributions to China's pipeline construction.
