At present, the valve has become one of the fastest growing industries in China's equipment manufacturing industry. The types of valves are constantly increasing, and the requirements of various industries for valve quality and technology are also getting higher and higher. However, like most of the machinery industry, China's valve industry is also facing the bottleneck of the late start, the bottom of the poor development. Enterprises in the procurement, most of them are more inclined to import products, and even those in the industry believe that "domestic goods as joint stock, joint stock is not as good as imported goods." The so-called imported goods, refers to the original imported products, from research and development to production completely in foreign countries of origin, strict implementation of foreign standards; joint venture, as its name suggests by the Chinese side and foreign investors jointly set up the project by foreign countries to provide technology, personnel, Brand, etc., in the domestic assembly, product implementation of European and American standards; domestic goods, it is by the Chinese own design, manufacture, implementation of GB products. Valve as a manufacturing base, in all walks of life have a wide range of applications, therefore, valve localization process has always been a national concern. After many years of hard work, China's valve localization has made very gratifying progress. For example, in the field of valves, the key valves of Nuclear Nuclear Power Supranuclear Nuclear Power Plant have made major breakthroughs; Kaifeng High-pressure Valve million-unit WB36 forged steel valves have been successfully developed; Chengda Chengda Valve Large-caliber Plate Valve, Suzhou Neway Valve Ball Valve In the "West-East Gas Pipeline" The successful application of pipeline ... ... In some areas of high demand, the development of our valve and industrialization have a good performance. In spite of this, when purchasing enterprises, they still lack confidence in domestically produced valves, especially in the high-end fields, but also pursue imports. So, domestic valves and imported valves which one is better? Today, we will analyze the following points. product quality There is no doubt that quality is the key factor that users choose a product. The use of the valve is usually harsh working environment, therefore, the valve quality and service life is very important. As foreign countries started the research on instrument valves earlier, in the processing equipment and research and development level, relative to the country is more advanced. But in recent years, our valve quality has also been greatly improved. In the 1980s, our country began to organize key enterprises to introduce advanced design, process and processing equipment from foreign instrument valves. After decades of absorption and digestion, the manufacturing technology and quality of our instrument valves have been greatly improved. In the field of low-end valves, domestic valve quality can be comparable to foreign countries. In the field of high-end valves, China is also increasing research and development efforts, continue to invest funds, and made a series of breakthroughs. Imported valve recommended index: ★ ★ ★ Domestic valve recommended index: ★ ★ ☆ price However, the price is said that in addition to quality, the user first select the product to consider the factors. Imported valves through the customs, to add one after another tariffs, fire tax, etc., coupled with China's relatively low labor costs, which makes the cost of domestic valves far lower than the import valve. It can be said that the same material, the same effect, the price of imported valves is several times the domestic valve. At the same time, fierce market competition allows enterprises to increase market share, and strive to reduce production costs. In terms of cost-effective, domestic valves have more advantages. Imported valve recommended index: ★ ★ ☆ Domestic valve recommended index: ★ ★ ★ After-sales service Valve product sales service is the key to marketing management, the user increasingly concerned about the after-sales service. In this regard, domestic valves relative to the import valve, occupy the geographical advantage. Most domestic valve companies have professional engineers, and you can come to guide, provide a complete after-sales service. The import valve is more difficult to achieve timely after-sales maintenance of the product, returned work. Imported valve recommended index: ★ ☆ Domestic valve recommended index: ★ ★ ★ Taken together, domestic valves not only do not lose import valves, the sale and the price are slightly better. Prejudice often arise and come from do not understand, domestic valve of the technical strength and product quality has long been incomprehensible, giving more room for development and time, I believe that domestic valves will eventually be recognized by the user. Formic ACID has strong reducing ability and is a by-product of coking. Adding formic acid is more effective than adding inorganic acids such as H2SO4 and HCL, because inorganic acids have only acidification effect, and formic acid can not only reduce the pH value of silage, but also inhibit Plant respiration and poor microbial fermentation.
