Generally speaking, the price of hardware valves in China is relatively stable. Although there is a slight increase and decrease every year, the range is very small. In the North China valve market, many companies have found that the profits are shoddy, which seriously disrupts the valve market.
The main problems in the valve market are as follows: 1. Some operators who purchase unnamed factories and print famous brands and certificates of well-known manufacturers cause serious damage to the reputation of qualified valve companies. Second, the renovation of the valve, some operators through the re-painting of the old valve after the second sale, bringing serious safety risks to the project quality.
With the transfer of oil development to inland oilfields and offshore oil fields, and the development of thermal power from 300,000 kilowatts of thermal power to more than 300,000 kilowatts of thermal power and hydropower and nuclear power, it should also change its performance and parameters according to changes in equipment applications. Urban construction systems generally use a large number of low-pressure valves, and the development of environmentally friendly and energy-saving type, that is, the transition from low-pressure iron gate valves used in the past to environmentally friendly rubber-plate valves, balance valves, metal-sealed butterfly valves and mid-line sealing butterfly valves. Oil and gas transmission projects are developing in the direction of pipelines. From the perspective of energy conservation, it is necessary to develop steam traps and develop to high parameters of subcritical and supercritical.
The construction of power stations is going to be large-scale, so it is necessary to use large-diameter and high-pressure sums, as well as fast opening and closing valves. The needs of complete sets of projects have evolved from single varieties to multiple varieties and multiple specifications. The valve required for an engineering project is increasingly being provided by a valve manufacturer.
