塑料管材具有重量轻、耐腐蚀、导热系数低、绝缘性能好、不结垢,易着色、好施工安装和维修方便等优特点,它与金属管材相比,在生产与使用方面更能节约能源。尤其是不会腐蚀物质土壤,有利环境保护。将它运用于输水灌溉、邮电通讯线材包装等方面功效最大,大小口径不同规格的塑管年需求量不断攀升,市场开发前景看好。据有关部门的一项规划,到2000年地埋输水管将
Plastic pipe has the advantages of light weight, corrosion resistance, low thermal conductivity, good insulation performance, no scaling, easy coloring, good construction installation and easy maintenance, etc. Compared with metal pipe, it can save energy in terms of production and use. . In particular, it will not corrode the material soil and it is beneficial to environmental protection. It is most effective in water supply irrigation, post and telecommunication wire rod packaging, etc. The annual demand for plastic pipes of different sizes and sizes is constantly rising, and the market development prospects are promising. According to a plan of the relevant department, by the year 2000, buried water pipes will be
