目前,中国的塑料管道产量和使用量均占到了全球总数的一半左右。中国每年的塑料管产量约为1 100万t,而全球塑料管总产量大约为2 000万t。中国的这一数字是由中国塑协塑料管道专业委员会提供的,而全球的数字摘自美国市场调研公司Freedonia公司的一份报告。该报告预测,全球塑料管需求将以每年6.2%的速度增长,到2017年将达2 300万t。 At present, China’s plastic pipe production and usage account for about half of the global total. China’s annual output of plastic pipes is about 11 million tons, while the global output of plastic pipes is about 20 million tons. This figure in China is provided by the China Plastic Association Professional Committee, and the global figures are taken from a report by the U.S. market research company Freedonia. The report predicts that the global demand for plastic pipes will grow at a rate of 6.2% per annum and reach 23 million tons by 2017.
