I believe a lot of people for what is the ductile iron fittings is not very clear, it is actually a good eighteen more than using cast iron as raw materials, metal pipes and as a manufacturing production equipment using high-speed centrifuge. The pipeline while the production of raw materials are iron, but in the actual use of the process this is the performance of pipeline, and stainless steel tubes are very close, so in modern society, this kind of pipe is often used as a sewage treatment project, municipal construction and so on in liquid pipelines, moreover, the pipeline can also be used as natural gas, gas pipeline gas and so on. But for relevant personnel if they want to ensure the pipeline, the maximum effect of the use of words, so in the process of using, they must pay attention to the correct The installation mode of transportation. Because of this kind of ductile iron pipes compared to other pipeline is relatively heavy, so in the process of pipeline transportation, related personnel must pay attention to the fixed pipeline, otherwise the pipeline will fall and so on. When installing ductile cast iron pipe, the installation staff should also avoid using hard tool tap on a pipe.
