Valve manufacturing industry needs to keep up the level of international standards

Valves Branch of China General Machinery Industry Association, in the next 10 years, major projects of thermal power, nuclear power, hydropower, large petrochemical, oil and gas gathering and transportation pipelines, coal liquefaction and supporting new products, valves and metallurgical and other construction lesson, focus will be on development, growth is expected to drive the entire valve market. 

According to reports, the next 10 years, China will have more than 20,000 kilometers of oil pipeline construction and more, including Russia, Kazakhstan and other transnational oil pipeline. In addition, following the "East", but also more than 20,000 km of cross-border gas pipeline construction and branches. These projects require more than 20,000 or so of large diameter and small diameter pipeline valve, flat valve; will be built built 10-20 million ton large-scale oil refinery, renovation, expansion of large number of 800,000 one million tons of ethylene device has been approved? and PTA plant is applying for 50 to 60 million tons / year have more than a dozen large, it will give Zigong valve industry provides a huge market, the valve industry; building large fertilizer and ammonia plant will also provide an opportunity for valve manufacturing; another direct coal liquefaction is likely to form a new industry, due to the high temperature coal direct liquefaction process medium, high pressure, high solids, high demands valve models, will form an emerging market. 

According to the Association to experts, in the development of these new valves, attention should be paid to promote the application of new technologies, such as large-caliber long pipeline ball valves should be used as a whole, the overall development of welding technology; to improve the valve sealing surface corrosion and erosion, a few manufacturers have started using tungsten carbide HVOF process, but pay attention to the development of nano-materials sealing surface modification coating, laser cladding technology. In addition, cobalt - chromium - tungsten years automatic plasma welding process valve industry should continue to promote the application to replace the manual welding, ensuring quality valve sealing surface; process to achieve automatic control engineering equipment, should be strengthened intelligent electric, hydraulic development actuator valve; accelerate the transfer of new methods, such as magnetic drive, magnetic drive the development of new developments closed valve, eliminate leakage between the stem and the packing for flammable, explosive, toxic, corrosive media is locked and requirements in order to prevent misuse by pipeline. 

To this end, the valve industry should form enterprise groups, investments in technology, high, high, fine, sharp valve product development; strengthen the standardization of products, so that standards need to keep up with the number and level of development of the situation.
