衬塑给水管及管件

介绍了衬塑给水管件的结构、性能、材质、应用范围和执行标准。通过具体分析衬塑复合钢管和内复不锈钢净水管的特点，指出在外层钢管的内壁复衬聚乙烯塑料管或薄壁不锈钢管，既大大提高了钢管在输水、输热水、输煤气过程中的耐腐蚀性能，又保留了镀锌钢管采用螺纹联接密封性好、机械强度高、价格低廉的优点，是输气输水钢管升级换代的理想产品。

Lining Plastic to Supplying Pipe and Pipe Fittings

It introduces the structure,performance,material,appliance scope and implementing standard of lining plastic to supplying water pipe and fittings.It also analyses characteristics of lining plastic compound pipe and lining stainless steel pipe,put forward lining polyethylene or thinner wall-thickness stainless steel pipe to inside wall of outside layer pipe,thus it not only greatly enhance the pipe anti-corrosion property during transmitting water,hot water and coal gas,but also retain the advantages of galvanized pipe,such as sealing better with thread connection,high physical stress and low price.It will be ideal substitution for transmitting water and gas pipe.
