Standardization Of Pneumatic Ball Valve Manufacturing And Development

According to the experts of the association, we should pay attention to the popularization and application of new technological skills when developing new products of these valves, such as all welding skills for developing large-caliber ball valves in long-distance pipelines; in order to improve the corrosion resistance and erosion resistance of valve sealing surfaces, a few manufacturers have begun to use the supersonic flame spraying tungsten carbide process, together with other manufacturers. Emphasis is laid on the selection of nano-materials to modify the sealing surface and the development of laser cladding technology. In addition, cobalt chromium tungsten plasma wire feeding active surfacing technology used in valve industry for many years should continue to be promoted to replace manual welding to ensure the quality of valve sealing surface; in order to complete the active control of process flow of Engineering equipment, the development of intelligent electric and hydraulic transmission equipment valves should be strengthened; and the development of new transmission side should be accelerated. For example, magnetic transmission, the development of new closed magnetic transmission valve series, eliminating leakage between stem and filler, pneumatic ball valves make it suitable for inflammable, explosive, toxic, corrosive media and requirements to determine, prevent misoperation pipelines.

It is reported that in the next 10 years, more than 20,000 kilometers of oil pipelines will be built in China, including transnational pipelines such as Russia and Kazakhstan. In addition, China will build more than 20,000 kilometers of transnational gas pipelines and feeder lines after the "West-to-East Gas Transmission Project". These projects require more than 20,000 large-caliber pipeline ball valves, medium and small-caliber ball valves and flat valves; 10-20 large-scale refineries of 10-20 million tons will be built, a batch of 800,000-1,000,000 tons of large-scale ethylene equipment will be built, rebuilt and expanded, and more than a dozen sets of large-scale PTA equipment of 500,000-600,000 tons/year have been batched and to be batched, which will serve as valves. Industry supplies a huge shopping mall; the creation of large-scale chemical fertilizer and ammonia plant will provide opportunities for valve manufacturing industry; other coal direct liquefaction is likely to constitute a new industry, because of the high working temperature, high pressure and high solid particle content of coal direct liquefaction process media, high requirements for valves will be formed. A new shopping mall.

To this end, the pneumatic ball valve profession should form an enterprise group, increase investment in science and technology, develop high, large, fine and pointed valve products, and strengthen product standardization to keep up with the development of the situation in quantity and level.
