Hardware valve market chaos clustered companies shoddy

The main problems in the valve market are as follows: First, some operators purchase brand names and certifications from well-known manufacturers without purchasing plant names, causing serious damage to the reputation of qualified valve companies. Second, refurbishment of the valve, some operators re-painted the second time after the waste valve re-painted, giving the project quality a serious security risk.

With the shift of oil exploration to oil fields in the interior and offshore oil fields, and the development of thermal power and hydropower and nuclear power from 300,000 kilowatts to less than 300,000 kilowatts in the power industry, the performance and parameters should be changed accordingly in accordance with changes in the application fields of equipment. Urban construction systems generally use a large number of low-pressure valves, and are developing towards environmental protection and energy-saving, that is, the low-pressure iron gate valves used in the past have gradually shifted to environmental-friendly rubber sheet valves, balancing valves, metal sealing butterfly valves and midline sealing butterfly valves. Oil and gas transmission projects are developing in the direction of pipelines. From the perspective of energy conservation, steam traps have to be developed and developed to subcritical and supercritical high parameters.

The construction of the power station has grown to a large scale, so the sum of large diameter and high pressure is needed, and at the same time, valves need to be opened and closed quickly. The needs of a complete set of projects evolved from a single species to multiple varieties and multiple specifications. The need for a valve for an engineering project is increasingly provided by a valve manufacturer.
