摘　　要：针对市场上给水螺纹管件存在的问题,我们在外镀锌内涂塑可锻铸铁管件的塑粉涂料和机械加工工艺方面做了较大改进,较好地解决了小于DN100热镀锌内涂塑钢管的接口螺纹连接涂塑膜质量问题,保证了管件的防蚀和密封性能,使涂塑管路全程性能得到保证,整体管路和高层建筑同寿命,免维修。For the shortcoming of thread fittings for water supply,we do great progress in plastic powder and mechanical processing technology for the malleable iron hot-dip galvanizing fittings ,the quality of plastic membrane was solved in thread connection fittings of the DN〈100 outside surface coated galva- nizing inside surface plastic-coating steel tube.Better anti-corrosion and seal performances of the fittings ensure the full performance of the coating pipe.The life of overall coating pipe are the same as the high-rise buildings and maintenance-free.
