The development of plastic hose in China

Our country the development of plastic pipe plastic pipe has light weight, corrosion resistance, small water loss, installation is convenient wait for a characteristic, get the favour of the pipeline engineering, at the same time because of the plastic pipe compared with the traditional metal tubes, it produces less energy consumption, Generally less than 1:4) , the environmental pollution is small, now is becoming more and more attention by the government and related departments. Abroad, plastic pipe material are alternative metal or other traditional materials of pipes, developing very rapidly. The rate of 2% growth, the output value is about increasing at a rate of about 8% a year. Since the seventy s in China plastic pipe, in the early eighty s began to popularization and application in the engineering construction. Over the past twenty years, the plastic tube got great development, not only in quantity, and got great development in varieties and specifications. By the end of 1999, the national plastic pipe production line more than about 2000, including the introduction of equipment accounted for about 15%. In 1999 our country all kinds of plastic pipe production capacity has reached 1. 65 million tons, the actual output is 1 million tons. Among them, the PVC - U tube 500000 tons, accounting for 50%; PE pipe 360000 tons, accounting for 36%. In recent years, along with the construction industry become the important pillar industry of national economy and the rapid development of housing industry, building indoor plastic pipe development soon, has now become a hot spot in today's investment. The development of plastic pipe, the current mainly UPVC pipe and PE pipe, and vigorously develop new composite, modified plastic pipe. In 2010, the main products of plastic piping to meet the market requirements, complete market products, quality, grade and level has obviously improved, the overall level of close to international advanced level. In the building, rebuilding and expansion projects, building a drain 80% use plastic pipe; Building water supply, water supply and heating tube 80% use plastic pipe; Wire to protect the casing 90% use plastic pipe; Building rainwater drain 70% using plastic pipe; City water supply pipe ( Below DN400Inm) Use plastic pipe water supply 70% 70% by plastic pipe, villages and towns; Urban drainage pipe 50% use plastic pipe; City gas pipeline ( In the low pressure pipeline) 60% used plastic pipe.
