The Development And Market Prospect Of Flexible Reinforced Thermoplastic Pipes
In recent years, the construction, municipal administration, water conservancy, agriculture and industry and other industries on the increasing demand for plastic pipeline, promoting the development of China's plastic pipeline industry. China's plastic pipe industry has made great achievements in improving production capacity and application amount, increasing product categories, expanding application fields, promoting industrial scientific and technological progress, and strengthening standardization construction, and has become a big country in the production and application of plastic pipes. During the 12th five-year plan period, the growth rate of plastic pipes will remain around 10%. It is estimated that by 2015, the national output of plastic pipes will exceed 13.2 million tons, and the market share of plastic pipes in all kinds of pipes will exceed 50%.
Plastics have many recognized unique advantages, but low strength is their obvious disadvantage. Therefore, the application of full plastic pipe is bound to be limited. Using other high strength materials and plastic composite, the manufacture of reinforced composite pipe has been a subject of domestic efforts to explore. Steel pipe has the advantages of high strength and can be used in high pressure range, but it has the disadvantages of easy oxidation corrosion, short service life and complex construction. Plastic pipe (such as PE pipe) is just the opposite of steel pipe. Plastic pipe corrosion resistance, construction is simple, but because of low strength, can only be used in the middle and low pressure range, and most can not be made into coil. In order to overcome the shortcomings of plastic pipe and steel pipe, various structural forms of composite pipe came into being. Reinforced thermoplastic pipes (RTP), which can be made into long continuous coils, have unique advantages over metal pipes. As soon as the Reinforced thermoplastic pipes appeared, it received hot pursuit from related industries. At the same time, RTP composite pipe production process is advanced, low cost, excellent performance, less construction costs and easy to support technology, so the universal attention. The United States, Germany, France, Britain, Japan, Russia and other countries as early as the 1970s began to research reinforced thermoplastic pipes (RTP) composite pipe production technology, has been put into industrial production.
