high large-diameter welded ball valve for localization of key equipment

Recently, developed by domestic enterprises key to long gas pipeline equipment - high-pressure large-diameter welded ball valve through the factory identification. Industry experts said that this means that the key to long gas pipeline development of the localization of equipment to achieve substantive results, will accelerate the electric drive and fuel displacement compressors of domestic development.

    Speed ??localization of key equipment
    July 15 to 19, into a high valve company in Chengdu, Shanghai Neles   valves, Zhejiang Wuzhou Valve Company, respectively, of the 10 developed high-pressure large-diameter welded ball valve in Chengdu, Shanghai, Wenzhou, passed the factory Identification of cum acceptance. cable tray pricing
    It is understood that identification of cum factory acceptance by the State Energy Bureau of the participating experts and user units composed of representatives of the Committee of Experts, listened carefully to the research unit's research summary report, units of Quality Supervision, Inspection and supervision unit test reports of new product trial witness (supervision) report, inspected the manufacturing plant, process equipment and the development of products, and witnessed some of the product performance test sampling.
    Jianding cum Acceptance Committee believes that research and development unit of the product design is reasonable, reliable performance;
 welding technology programs to ensure the quality, performance test and identification test items, content and results are developed to meet the contract and related standards; process equipment manufacturing enterprises, testing and quality assurance system with mass production conditions. Agreed to identify and product acceptance by the factory.
    I understand that high-pressure large-diameter welded ball valve is the key to long gas pipeline is one of the devices, long distance gas pipeline to cross the deserts, swamps, mountains, rivers, geographical, geological situation is complex, climate, poor environmental conditions, to ensure safe and reliable operation of energy artery, requiring the valve has a higher reliability, tightness and strength, service life more than 30 years, the development is very difficult, in the design, materials, manufacturing and other aspects of the proposed development of a high unit requirements.
    According to the National Energy Board stakeholders, at present, China's Natural Gas Pipeline construction, more than 40 inches diameter welded ball valve high pressure mainly depend on imports, not only the products are expensive and difficult to service. The three units of products developed through the identification of cum at the same time acceptance, will greatly speed up the long distance gas pipeline welded large-diameter high-pressure valve of the domestic process.
