subject: The China Valve Development Of 2010 Facing The Transformation [print this page] With the transfer of oil development towards mainland and offshore, as well as the power industry changing from under 300,000 kilowatts thermal power to above 300,000 kilowatts of thermal also hydropower and nuclear power, corresponding changes in its performance and parameter shoule be based on changes in equipment applications. Urban systems are generally use a large number of low-pressure valves, and to the development of environment-friendly and energy-saving, that is, from a low-voltage iron gate valves used in the past gradually shifted environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the center line butterfly valve sealing. Oil and gas transmission projects to develop in the direction of the pipeline. From the energy conservation perspective, the steam trap should be developed, and to the high parameters development of the sub-critical and supercritical.
The construction of the power plant move to the large-scale development, and therefore it requires larger diameter and higher pressure and also need quick-open and close valve. The needs of the complete works develop from single species to a multi-species and multi-standard. The valves required for one project are all provided by an exclusive valve manufacturer has become the trend. Such as Guanfa Valve
Generally speaking, China's price system is relatively stable, although has a slight up or down every year. According to the North China valve market, we found a number of companies make a profit shoddy, they disturbed the valve market badly. The main problems in the valve market are: First, some of the operators purchase the factory site of non-factory name, and print the brand-name and the certification of the well-known manufacturers, this cause serious harm to the reputation of businesses of qualified valve. Secondly, valve refurbishment, some of the operators do the second time sales through re-paint the waste valve, it bring serious security risks to the quality of the project.
