Valve products of domestic enterprises are developing in the direction of energy saving, environmental protection and green

by:Sino Valves     2021-03-02
The domestic demand and export value of valve products are showing an upward trend every month and every quarter. The overall situation is performing well, and the competition among domestic valve companies is gradually improving. Products are developing in the direction of energy saving, environmental protection and green. The valve industry plays a very important role in the development of the national economy as an important part of preparing for the manufacturing industry. As there is still a certain gap between the level of China’s domestic valve manufacturing industry and the international advanced level, many key valves with high parameters, high temperature and pressure, and high pounds have been dependent on imports. In order to promote the localization of valves, the State Council issued the 'About Accelerating Revitalization After the 'Several Opinions on the Equipment Manufacturing IndustryDeployed and formulated valve localization plans for major equipment in related fields, and coordinated with relevant departments many times. Nowadays, valve localization has reached a consensus in the domestic valve industry. At present, my country's valve manufacturing industry has been able to provide user departments with about twelve categories, more than 3,000 models, and more than 4,000 specifications. Its performance parameters range from vacuum valves to 600Mpa ultra-high pressure valves, and the temperature ranges from cryogenic 196 degrees Celsius. To a high temperature of 570 degrees Celsius. Its main products have basically been able to meet the needs of the domestic market, and the complete set rate, complete set level and complete set capacity of the valve market have been greatly improved, and domestic valves have already had a certain foundation for revitalization. With the transfer of petroleum development to inland oil fields and offshore oil fields, and the development of the power industry from thermal power below 300,000 kilowatts to thermal power and hydropower and nuclear power above 300,000 kilowatts, products such as breathing valves, flame arresters, filters, pipe sight glasses, etc. The performance and parameters of the equipment should also be changed according to changes in the application field of the equipment. Urban construction systems generally use a large number of low-pressure valves, and they are developing towards environmental protection and energy-saving. That is, the low-pressure iron gate valves used in the past are gradually shifting to environmentally-friendly rubber plate valves, balance valves, metal seal butterfly valves, and centerline seal butterfly valves. The development of oil and gas transmission projects towards pipelines requires a large number of flat gate valves and ball valves.     The other side of energy development is energy saving. Therefore, from the perspective of energy saving, steam traps should be developed and developed towards subcritical and supercritical high parameters. The construction of power stations is developing towards large-scale development, so large-diameter and high-pressure safety valves and pressure reducing valves are needed, and fast opening and closing valves are also needed. For the needs of complete sets of construction machinery, the supply of valves has developed from a single variety to multiple varieties and specifications. There is a growing trend that a single valve manufacturer provides all the valves required by an engineering project.     Generally speaking, the valve market price in my country is relatively stable. Although there is a slight fluctuation every year, the range is very small. Judging from the North China valve market, it was discovered that many companies used shoddy profits for profit, which seriously disrupted the valve market. The main problems in the valve market are: 1. Some operators buy valves without a factory name and print the nameplates and certificates of well-known manufacturers, causing serious harm to the reputation of qualified valve companies. 2. Refurbished valves. Some operators repainted the used valves and sold them for the second time, which brought serious safety hazards to the project quality.     Through the analysis of the valve market, it is not difficult to find that my country's valve product market has a good development prospect, but it is necessary to standardize the market order and strict management to eliminate vicious competition and enhance the overall competitiveness of the industry itself.
