Pneumatic ball valve level will gradually keep up with the development situation

Pneumatic ball valve learned from the Valve Branch of China General Machinery Industry Association that in the next 10 years, new valve products for thermal power, nuclear power, hydropower, large petrochemical, oil and gas gathering and transportation pipelines, coal liquefaction and metallurgy will be developed. The focus is expected to lead the rapid increase in the entire valve market.
According to the experts of the association, in the development of these new valve products, we should pay attention to the promotion and application of new process technologies. For example, the development of long-distance pipeline large-diameter integral ball valves should adopt the overall welding technology; in order to improve the corrosion resistance and erosion resistance of the valve sealing surface, a few Manufacturers have begun to use supersonic flame spraying tungsten carbide process, while paying attention to the application of nano-scale materials to the modification of the sealing surface, and the development of laser cladding technology. In addition, the cobalt-chromium-tungsten plasma wire automatic surfacing process applied in the valve industry for many years should continue to be promoted to replace manual welding to ensure the quality of the valve sealing surface; in order to realize the automatic control of the engineering process, the intelligent electric motor should be strengthened. Development of hydraulic transmission valve; speeding up the development of new transmission methods such as magnetic transmission, developing a new series of closed magnetic transmission valves, eliminating the leak between the valve stem and the packing, the pneumatic ball valve makes it suitable for flammable, explosive, Toxic, corrosive media and pipelines that require locking and avoiding misuse.
According to reports, in the next 10 years, China will have more than 20,000 kilometers of oil pipelines to be built, including transnational oil pipelines such as Russia and Kazakhstan. In addition, following the "West-East Gas Transmission", China will build more than 20,000 kilometers of transnational gas pipelines and feeder lines. These projects require about 20,000 large-diameter pipeline ball valves and small and medium-sized ball valves and flat valves. They will also build 10 to 20 million-ton large-scale refineries, and build, rebuild and expand a batch of 800,000 to 1 million tons of large-scale ethylene. There are more than a dozen sets of 500,000-600,000 tons/year large-scale PTA units approved and approved, which will provide a huge market for the valve industry; the construction of large-scale fertilizer and ammonia plants will also provide opportunities for the valve manufacturing industry. In addition, direct coal liquefaction is likely to form a new industry. Due to the high working temperature, high pressure and high solid content of the coal direct liquefaction process, the valve has high requirements and will form an emerging market.
To this end, the pneumatic ball valve industry should set up enterprise groups, increase investment in science and technology, develop high, large, fine and sharp valve products; strengthen product standardization work, so that standards can keep up with the development of the situation in quantity and level.
