China's high pressure valves urgently need to be domesticated

Under the continuous optimistic view of the macro-economy, most of the valve industry's production and sales indicators have maintained rapid growth. However, affected by the price war, the industry's sales revenue and profits have dropped significantly from the same period of last year. With the recovery of the world economy, China's valve products have also experienced an increase in imports and exports. However, due to the large gap between high-end technology and foreign manufacturers, the product technology will become a constraint on the development of China's valve products in the future. bottleneck.

In China's current valve market, high-pressure valves still need to rely on imports, except for low-pressure valves that are acceptable in the international market. Under the continuous optimistic view of the macro-economy, most of the valve industry's production and sales indicators have maintained rapid growth. However, affected by the price war, the industry's sales revenue and profits have dropped significantly from the same period of last year. With the recovery of the world economy, China's valve products have also experienced an increase in imports and exports. However, due to the large gap between high-end technology and foreign manufacturers, the product technology will become a constraint on the development of China's valve products in the future. bottleneck.

From the product point of view, China's valve industry has now been able to produce more than 10 categories of products, such as gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, pressure reducing valves, diaphragm valves, Traps, emergency shut-off valves, etc., the maximum operating temperature of 570 °C, the lowest is -196 °C, the maximum pressure of 600MPa, the maximum diameter of 5350 mm. In addition, according to relevant department statistics, China's annual valve market turnover as high as 50 billion yuan, of which more than 100 billion yuan of the market was occupied by foreign valve companies. Valves are indispensable fluid control equipment for various departments of the national economy such as petroleum, chemical industry, power stations, long-distance pipelines, shipbuilding, nuclear industry, various cryogenics, aerospace, and marine oil extraction. After years of development, the number of valve companies in China ranks first in the world. There are about 6,000 valve companies of all sizes, of which 900 have an annual output value of more than 5 million yuan.

At present, China's valve industry still has some problems, such as China's valve companies mainly in low-level, small-scale, family workshop-based enterprises. In terms of products, due to repeated investment and inadequate technology introduction, the leading products of China's valve companies are still low-quality mass products. At present, various types of valves produced by enterprises in China have the disadvantages of external leakage, internal leakage, low appearance quality, short life span, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to the early 1980s. At the international level, some valves required on high temperature and high pressure and critical devices still rely on imports.

China's valve industry in the industrial structure, the industrial chain of the valve industry, as well as the industry's degree of specialization and foreign companies have a large gap between the quality of the domestic valve products caused by the low: due to the rapid expansion of the market, the original state-owned valve companies have Closed and transferred, although a group of township enterprises developed rapidly, but due to the low starting point of the township and village enterprises, the technical force is very weak, and the equipment is simple, most of the products are imitating production, especially the low pressure valve for water supply and drainage is serious but the above problems are also Does not affect the broad prospects of China's valve industry in the future. This is mainly due to the support of national policies and the strong demand for valve product markets. In particular, several projects of the “West-to-East Gas Transmission”, “West-to-East Electricity Transmission”, and “South-to-North Water Transfer” projects require a large number of valve products to be started. .

In addition, China is facing the arrival of the era of industrialization. The petrochemical industry, the power industry, the metallurgical industry, the chemical industry, and the construction of cities and other large-scale valve users will increase the demand for valve products. For example, in the electric power industry, during the “11th Five-Year Plan” period, the total valve demand forecast for large- and medium-sized projects in coal-fired power plants is: total demand for valves is 153,000 tons, average annual demand is 30,600 tons, and total valve demand is 3.96 billion yuan. The average annual demand is 792 million yuan. In addition, China is gradually becoming the largest processing plant in the world, and the processing and manufacturing of valve products face greater development space. Therefore, as long as companies can seize opportunities, strengthen research and development capabilities, and continuously improve product technology content and product quality, Take the initiative in the fierce market competition.
