Plastic hose application in various industries and the development speed

Plastic hose in a variety of different industries on the application and development in foreign countries, plastic tubing is replacing the metal pipes or other traditional material, is developing very quickly. From 80 s to 90 s in the 10 years or so, in addition to plastic tubes, pipes of various materials, the growth rate of less than 2%, but the growth rate of plastic pipe is four times that of other kinds of pipes, the growth rate of 8%, to the demand of plastic pipe is 4 per year in the ninety s. Growth of 2%, the output is growing at about 8% per year. Since the 1970 s in China plastic pipe material, in the early 80 s began to popularization and application in the engineering construction, over the past 20 years, plastic pipe material, regardless of the number and varieties, specifications have made considerable development. By the end of 2000, China about 2000 plastic pipe production lines, including imported equipment accounted for about 15%. In 2000, our country all kinds of plastic pipe production capacity of 1. 65 million tons, the actual output of about 1 million tons. Among them, the PVC - The U tube 500000 tons, accounting for 50%; PE pipe 360000 tons, accounting for 36%. In recent years, as construction has become an important pillar industry of national economy and the rapid development of housing industry, building the indoor plastic pipe has been developing rapidly, has now become investment hot spot. At present, the development of plastic pipe are mainly composed of UPVC pipe and PE pipe, develop the new type of composite modified plastic pipe. In 2010, the main products plastic tubing to meet the market requirements, complete market products, quality, grade and level has obviously improved, the overall level of close to international advanced level. 80% of the building, rebuilding and expansion of engineering construction using plastic drainage pipes. 80% of the water supply, hot water use plastic pipe, heating pipe; 90% of the wire casing use plastic pipe; 70% of the buildings of rainwater drain use plastic pipe; 70% of urban water supply pipeline and 70% of rural water supply pipeline in plastic pipe. 50% of the urban drainage pipe, plastic pipe 60% of the city gas pipeline in plastic pipe.
