In the past few years, the trend of “outward†development of domestic industrial valve companies was quite obvious. At that time, although there were many internal enterprises in the industry, due to the low cost and fierce competition, most companies were relying on lowering the price of their products to obtain a market. As a result, corporate profits are very low. Basically, they can only reach the state of maintaining production, but it is difficult to make money. The consequences are low product prices, low added value, and low profits. Companies do not have sufficient funds to continue to develop. If the enterprise can not progress, the industry will be difficult to upgrade, resulting in unsatisfactory results. Enterprises do not have enough funds to ensure that product design and technological content can not be improved, plagiarism and accepting orders from overseas companies become the ultimate choice for business survival. This will inevitably lead to the absence of domestically produced valve accessories in the high-end market.
In the continuing favorable macroeconomic situation, most of the valve industry's production and sales indicators have maintained rapid growth. However, because of the price war, sales revenue and profits of the industry have dropped significantly from last year. In general, however, the industrial concentration of China's pump and valve market is relatively low, and the production of medium and low-end products is the mainstay. In terms of owning core technologies, there is still a certain gap between domestic enterprises and developed countries in the world.
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 insufficient technology introduction, the leading products of China's valve companies are still low-quality mass products. It is understood that currently all kinds of valves produced by Chinese enterprises have the drawbacks of external leakage, internal leakage, poor appearance quality, short life span, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to the last century. At the international level in the early 1980s, some of the valves needed for high temperature and high pressure and critical equipment still depended on imports.
China's valve industry in the industrial structure, the industrial chain of industrial valves, as well as the industry's degree of specialization and foreign companies have a large gap between the quality of domestic valve products caused by the low: due to the rapid expansion of the market, the original state-owned valve companies have Shut down and switch. According to a survey conducted by the Air Conditioning and Refrigeration Market, although a number of township and village enterprises have developed rapidly, due to the low starting point of the township and township enterprises, the technical strength is very weak, equipment is poor, and most of the products are modelled on production. In particular, the problem of low pressure valves for water supply and drainage is serious. The above problems do 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 Transmissionâ€, “West-to-East Electricity Transmissionâ€, and “South-to-North Water Transfer†projects require a large number of valve products .
Last year, China's valve industry import and export totaled 24.1 billion U.S. dollars, a year-on-year increase of 28.2%. The total export value was 22.4 billion U.S. dollars, a year-on-year increase of 29.3%; the total import volume was 20.134 billion U.S. dollars, a year-on-year increase of 27%. With the warming 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 coming period. bottleneck.
Until recently, Chinese valve makers were limited to a few profitable target markets such as Ethiopia, Sudan, Iran, Iraq, and some Southeast Asian markets. These markets are small in scale, and the decision-making process is entirely dependent on prices, with limited profit margins. China's import valve manufacturers must pay attention to such an undeniable fact: If they want to survive in the future, they must improve their previous sluggish performance and gain large profits for export. The main reason for the current lack of export revenue is the large number of business opportunities in the Chinese domestic market, and the quality of equipment manufactured by China's imported valves is not enough to sell overseas.
Single Plug Cement Head
The single plug cement head is used to store a lower rubber plug (or upper rubber plug) before the rubber plug is pumped into the casing during the cement injection process. The general practice is to install the lower plug and put it in front of the isolation fluid or cement slurry. Then open the cement head, install the upper plug between the two inlets, put it in after pumping the cement slurry.
Single plug cement head is a special tool used to inject grout and release rubber plug. Single plug cement head can be connected with casing.
1. The single-plug cement head has novel structure and reasonable design. The main body is made of high-strength alloy structural steel and is resistant to high pressure.
2. The DSC cement head is equipped with a quick-fitting joint, which is convenient to connect, and can be connected with API long round buckle/short round buckle/trapezoid buckle, and has a wide range of use.
3. The rubber plug drop indicator is designed to facilitate on-site operators to judge whether the rubber plug has passed.
4. The cement head is equipped with a balance pipe, so that the pressure at the upper and lower ends of the rubber plug during cement injection is the same, eliminating the negative pressure suction caused by the stop pin
