Valve manufacturing level to keep up with the needs of the development of the situation

At present China from general machinery industry association valve to understand, the future chapter 10 years, thermal power, nuclear power, water and electricity, large oil chemical, oil and gas gathering and transportation pipelines, coal liquefaction and metallurgical and other major construction of new products, supporting the valve will be the key to the development of the market leading China Valve high growth.

According to introducing, the next 10 years, China will have more than 20000 kilometers to the oil pipeline construction, including Russia, kazakhstan transnational oil pipelines. In addition, the "west-east gas transmission", our country also after construction of more than 20000 kilometers of the multinational gas transmission pipeline and regional. The project is about more than 20000 only big diameter pipeline ball valve and small and medium-sized diameter ball valve, the valve plate; Will also construction 10 to 20 a large refineries, and new construction, expansion a batch of 800000 ~ 100 large ethylene plant, has DaiPi group and the 500000 ~ 600000 tons/year large PTA plant also has more than ten sets of, this will be for the China Valve industry provides a huge market; Large chemical fertilizer and the construction of the ammonia plant also will provide opportunities for valve manufacturing; Another coal liquefaction directly is likely to form a new industry, because coal liquefaction process work directly to the high temperature, medium high pressure, high content of solid particles, the valve is very high request, will form a new market.

According to expert introduction, in the development association of new products, the valve should be paid attention to the popularization and application of the new technology, such as the development of large diameter long distance pipeline whole ball valve should adopt overall welding technology; In order to improve the corrosion resistance and valve sealing surface and erosion, a few manufacturers are beginning to use the supersonic flame spray and tungsten carbide and, at the same time, the process should be paid attention to nanoscale materials to the sealing surface coating modification, and the process of laser cladding technology development. In addition, DuoNian to the Hydrant Valve industry in application of cobalt chromium tungsten plasma wire automatic welding process should continue to promote to replace manual welding, to ensure that the valve seal face quality; To realize the process automation engineering device control, should strengthen intelligent electric, hydraulic transmission device valve development; To speed up the development new transmission ways such as magnetic transmission, the development of new type equipped with magnetic transmission valve series, eliminate stem and packing of the outer between, applicable to inflammable, explosive, toxic, corrosive medium and requirements lock, avoid mistake on the pipeline.

Therefore, the Hydrant Valve industry shall organize enterprise group, increasing investment in science and technology, the development of the high, big, refined, sharp valve products; Strengthen product standardization work, make the standard in quantity and level keep up with the needs of the development of the situation.
