The plastics industry rapid development of the auspicious prospect
Since the reform and opening up, China's chemical industry rapid development, for the manufacture of plastic products has laid a firm foundation, plastic pipe, pipe fittings production is make a spurt of progress, the annual output of about 2000000 tons of; of new materials, new technology, new products, widely used in construction, municipal systems ( water, gas ), power, telecommunications, agriculture and other industries.
In industrial pipes, plastic pipes have not been fully utilized. This is because on the one hand, industrial pipe fittings requirements than the industry high many, both to tolerance to high temperature and pressure, and tolerance to chemical corrosion or wear, At the same time need to be matched with the valve and instrument; on the other hand, as the plastic material with metal materials significantly different mechanical properties, for it at higher temperatures and pressures, chemical corrosion ability of tolerance and lack of experience, lack of complete data.
In the advanced countries, because the plastic material with unique properties, corrosion resistance, in the economic health and relative metal materials, showing there is nothing comparable to this advantage, in the industrial pipeline field application has been very common, and there have been some successful experiences. How will the plastic pipe applied successfully in our country industrial piping, safety use, long-term benefit, not only is in response to state for energy saving, material saving policy call, it is construction managing model economy. To realize the sustainable development of basic national policy of materialization and implementation. Make plastic pipe in the field of industrial design and application become more scientific, more safe and reliable.
