The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.

For packaging machinery and equipment with large market demand and great technical difficulty, China's food machine companies need to focus on the advantages of the industry, take the road of integration of production, learning, and research, organize and conduct targeted digestion and research, and develop research and development. The intellectual property packaging machinery breaks the foreign technology monopoly and accelerates the upgrading of China's packaging technology and self-sufficiency. At present, the global demand for packaging machinery is growing at a rate of 5.3% per year. The United States has the largest manufacturer of packaging equipment, followed by Japan, and other major producers also come from Germany, Italy and China. However, the fastest growing production of packaging equipment is in developing countries and regions.
Demand for packaging machinery rises
Food and beverage packaging is the largest market segment in the packaging machinery and equipment industry. The production of beverage packaging equipment is mainly the entire growth line, with a high degree of automation. At present, the per capita consumption of beverages in China, especially mineral water, and the advanced countries in the world There is a large gap between the levels, the market space is large, and our country has a large population. If the rural market is developed, the demand is very considerable.
Pharmaceutical industry packaging, the overall characteristics of such packaging machinery and equipment is small, high prices, production value of about 12-15% of the drug. Therefore, this type of packaging equipment also requires a higher level of automation, and the corresponding enterprise's ability to purchase automated equipment is also strong. At present, the national pharmaceutical reform can only be more stringent for packaging requirements, especially Western medicine, in order to avoid secondary pollution as much as possible in bulk. Traditional paper subcontracting bags have basically been eliminated. This market will also maintain a steady increase above GDP.
The application of packaging machinery and equipment in daily chemical industry is also relatively extensive. The daily chemical packaging is similar to the medical packaging. It is small in size and high in price. Many mechanical equipment and pharmaceutical packaging machinery and equipment can be shared, such as: Star Packing Machinery Co., Ltd. paste filling machine, can be filled with daily chemical products, such as facial cleanser, shampoo, etc., this packaging equipment can also be used In the pharmaceutical industry, such as erythromycin ointment and other pharmaceutical products, with the development of the food industry, China's demand for packaging machinery and equipment will appear a big leap forward.
How to adjust
By 2010, China's packaging machinery may increase to 930,000 units (sets). However, extensive operations relying solely on increasing capital investment and expanding production capacity can no longer meet the needs of the development of the situation. China's packaging production has entered a new era of adjusting product structure and improving development capabilities. Technology upgrading, product replacement, and business management are industries. Important issues for development.
Adjust industrial structure, increase production concentration, promote specialization, serialization of production, improve product quality and adaptability to the market; accelerate the establishment of an innovation system, form the company’s self-development ability as soon as possible, and make China’s packaging machinery products perfect. Do fine, special, and strong.
The technological level of China's packaging machinery as a whole looks at the level of skills of advanced countries for 20 years, and it is at a disadvantage in the competition of product development, performance, quality, reliability, and service.
In terms of product structure, it should be market-oriented, change the current situation of low-tech-based, low-level competition, eliminate a group of low-efficiency, high-consumption, low-grade, low-value-added, labor-intensive products, and strive to develop efficient production Low-cost, large-scale complete sets of equipment and high-tech products for production and sales. In the packaging function, industrial and agricultural products tend to be refined and diversified.
China's packaging machinery can not keep up with the market
China's packaging machinery technology level can not keep up with market demand, the need for food companies to focus on R & D efforts to break the monopoly of foreign technology, improve the packaging technology and self-sufficiency.
