消防给水用双面涂覆钢管生产及应用

Production and Application of Double Coated Steel Pipe for Fire Water Supply

为了解决传统消防给水用管及其连接件自身防腐蚀、防结垢和抗菌等性能较差,严重影响使用效果的问题,引入了一种新型消防给水用管,即双面涂覆钢管。介绍了双面涂覆钢管防腐层材料的选型及其防腐机理,双面涂覆钢管的生产工艺、检验方法及安装应用等。分析认为,双面涂覆钢管不仅具有钢管的优点,又具有防腐性能优良、水力性能好、耐高温性能强、安装方法多样等优点,其应用范围必将越来越广。

In order to solve the some problems of traditional fire water supply pipe and fitting, which seriously affect the use effect, such as corrosion resistance, anti-scaling and poor antibacterial performance. A new type of fire water supply pipe was introduced, namely double coated steel pipe. In this article, it introduced steel pipe coating material selection and corrosion mechanism of double coated steel pipe, as well as production process, testing method, application and installation. The analysis indicated that the double coated steel pipe not only possesses the advantages of steel pipe, but also possesses some other advantages, including excellent anticorrosive performance, hydraulic performance is good, high temperature resistant performance is strong, installation method variety and so on;its application scope will be more and more widely.
