产品详情

      在我国很多地区,球墨铸铁管在中、小口径的给管与管之间的联接,采用承插式或法兰盘式接口方法;球墨铸铁,容许限制的转角必须有优胜的抗震性和密封性。

球墨铸铁管的主要成分有碳、硅、锰、硫、磷和镁等。执行标准 GB/T13295-2003 ISO2531/2003。


     球墨铸铁管定义使用18号以上的铸造铁水经添加球化剂后,经过离心球墨铸铁机高速离心铸造成的管道,称球墨铸铁管(Ductile Cast Iron Pipes),简称为球管、球铁管和球墨铸管等


------------------------------------------------------------------------------------------------

In many areas of our country, socket or flange joint method is used for the connection between medium and small diameter ductile iron pipes. For ductile iron, the allowable limited corner must have superior seismic resistance and sealing performance.


The main components of ductile iron pipe are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Executive standard GB / t13295-2003, ISO2531 / 2003.


Ductile iron pipe is defined as the pipe made of high-speed centrifugal casting by centrifugal ductile iron machine after adding nodularizing agent to No. 18 or above molten iron. It is called ductile iron pipes, which is called ductile iron pipe, ductile iron pipe and ductile iron pipe for short
