摘要
针对目前国内外涂塑复合钢管应用现状,以及加工工艺和接口方式中存在的问题,设计了新型接口结构和连接方式。通过室内外试验和工程应用证明,该新型涂塑复合钢管和接口具备优良的机械性能和防腐性,结构稳定,涂层光滑,密封可靠,能满足输水工程对管道的要求。同时降低了加工成本,安装便捷、效率高,节省工期,质量易控制。
Based on the worldwide application situation of the plastic-coated steel pipes and their problems in manufacture and connection style,a new kind of plastic-coated pipe with innovative joint structure and connection style was developed. Through indoor and outdoor trials and engineering application,it has been demonstrated that the new plastic-coated steel pipe and its connection had perfect mechanical properties,strong corrosion resistance,stable structure,smooth coating and reliable sealing,which can meet the requirements of pipelines in engineering projects. In addition,it owns advantages such as lower cost,easy installation,high efficiency,time saving,easily controlled quality etc.
