In terms of product imports, the annual import value was 5.166 billion U.S. dollars, a year-on-year increase of 21.9%. Among them, the measuring tool was 2.673 billion U.S. dollars, up 26.4% year-on-year; the small electric tools were 433 million U.S. dollars, up 16.1% year-on-year; the wrenches were 118 million U.S. dollars. USD, a year-on-year increase of 2.6%; Saw category was US$234 million, an increase of 35.3% year-on-year; Utilities tools were US$40 million, an increase of 53.8%; Pliers were US$36 million, a year-on-year increase of 28.6%; Garden tools were US$0.049 billion. , a year-on-year increase of 28.9%.
It is not difficult to find from customs statistics that traditional hand tool products represented by wrenches, pliers, and saws are still favored by overseas buyers, and the long-term growth rate of around 20% also proves that Chinese hand-tool products are taking over. Bigger market space. Exports of products such as small power tools, gardening tools, and kits have also increased further. This shows that the demand for such products in major markets in Europe and the United States has not been reduced due to the impact of the financial crisis. These products are the major consumers of DIY products.
What is noteworthy is the import aspect. Although the world’s largest wrench and pliers manufacturing companies are almost all in China, the import volume of these two types of products has reached nearly 150 million U.S. dollars; the measurement products are even more so, although there are Oriental Seiko, Great Wall Seiko, etc. A group of leading enterprises led the large-scale production enterprises in Zhejiang Province. In 2011, the export of measuring tools was 897 million US dollars, a growth rate of 50%, while imports reached 2.673 billion US dollars, maintaining a high growth rate of 26.4%, and the measurement of single product trades. The deficit reached 1.776 billion U.S. dollars, which is also rare in the entire hardware industry.
Some people in the industry believe that although China is the world's largest hand tool production base, most of its export tools are OEM-based. Many products are actually produced by domestic companies. Foreign well-known brands purchase and label back to the domestic market. Therefore, domestic tool companies urgently need to make more efforts in brand building and channel construction, to avoid the emergence of production companies to make hard money, and high profits for the foreign brands to earn the embarrassing situation.
When discussing this issue, Wang Qiuqin, secretary general of the Jinhua Tool Hardware Industry Association, said that in 2011 Jinhua’s tool manufacturing companies were basically producing at full capacity. Enterprises generally reflected that orders could not be made, and they wanted to expand production scale but were also subject to recruitment difficulties. . But even so, the profit level of the production enterprises is still very low. Except for a few big companies, profits can reach 20%, most companies' profits are below 10%.
One problem that tool owners are generally aware of is that the Heat has spent over a year, but not much money. The reason is because the product price cannot be sold, and more often it is competing at a low level of homogeneity. Lack of brand awareness and influence, lack of domestic and international market sales channels, making most companies lack of pricing power and market control, can only wait for dinner to wait for orders.
Of course, these are not achieved overnight. It may take quite a long time to realize. We hope that our production companies can realize this problem as soon as possible and gradually improve. Wang Qiuqin said.
Some people in the industry also believe that when our companies are still exporting, they are still winning by volume. The increase in sales actually does not bring about an increase in profitability. It is entirely dependent on the increase in the number of export products, which may become a constraint on the development of the industry. Hidden danger. In particular, the competitiveness of Taiwan’s tools and Indian tools in the international market has also caused great pressure on our companies.
Zhou Jihua believes that there are no hidden dangers. For many years, China’s tool development has been very healthy. High-speed, continuous, steady improvement in quality and market share have been expanding year by year. It is due to the rapid growth of the Chinese tool industry that the Western tool manufacturing industry has been shrinking year by year. . Of course, there is competition in the Chinese tool industry, such as India, or will the Chinese tool not become a volley of roses? In the future, as long as China's tool development maintains the current momentum of development and is not in a hurry to advance steadily, it will certainly be able to achieve the goal of a tool-building power.
Stainless steel ball Valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It is a new type of valve that is widely used.
The stainless steel ball valve can be closed tightly with only a 90-degree rotation and a small torque. The completely equal valve body cavity provides a low resistance, straight-through flow path for the medium. The main feature of the ball valve is its compact structure, easy operation and maintenance, stainless steel ball valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The ball valve body can be integral or combined. This type of valve should generally be installed horizontally in the pipeline.
Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve.
Stainless steel ball valve material: 202, 304, 316, 321
The working principle of stainless steel ball valve is to make the valve unblocked or blocked by rotating the valve core. It is easy to switch, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be eroded by medium, wide application range, diameter from small to several millimeters, As large as several meters, it can be applied from high vacuum to high pressure.
Stainless steel ball valves have been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other sectors, as well as people's daily life.
Stainless steel ball valves are divided into one-piece, two-piece and three-piece according to their composition.
Features of stainless steel ball valve
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length.
2. Simple structure, small size and light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, which has good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and the disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
China has become a tool-manufacturing country and is currently working hard to improve quality. According to customs statistics, in 2011, the export of tool hardware was 10.606 billion U.S. dollars, a year-on-year increase of 26.7%. Among them, small-sized power tools were 2.614 billion U.S. dollars, up 22.3% year-on-year; Saw products were 1.12 billion U.S. dollars, up 24.9% year-on-year; US$897 million, a year-on-year increase of 50%; gardening tools US$563 million, a year-on-year increase of 16.8%; pliers US$608 million, a year-on-year increase of 28.3%; Wrenches US$607 million, a year-on-year increase of 24.1%; kits 4.31 Billion U.S. dollars, a year-on-year increase of 15.9%.
