球墨铸铁管安装施工探究

Research on Installation and Construction of Ductile Iron Pipe

管道安装是水利枢纽工程中的重要步骤之一,涉及水利的运输安全,所以,在施工过程中需要严格遵守工程的相关规定,解决施工过程中遇到的每个问题,保障水利工程在运输过程中工艺质量。随着科学技术的发展,各种管道新工艺层出不穷。球墨铸铁管是低稀土硅钡镁球化剂在浇筑前加入铁水中,使石墨球化、应力集中降低而形成的铸铁管,管材本身具有很强的延伸率。

Pipeline installation is one of the important steps in the water conservancy project,which involves the transportation safety of water conservancy.Therefore,in the construction process,it is necessary to strictly abide by the relevant regulations of the project,solve every problem encountered in the construction process,and ensure the process quality of the water conservancy project in the transportation process.With the development of science and technology,a variety of new pipeline technologies emerge in endlessly.Ductile iron pipe is a kind of cast iron pipe with low rare earth silicon barium magnesium nodulizing agent added into molten iron before pouring,which makes graphite spheroidized and stress concentration reduced.The pipe has a strong elongation.
