我們的生活中離不開水，不論是吃的還是用的，最常見的就是自來水了吧。不知道你曾經(jīng)是否思考過自來水的輸送問題，那么，自來水管道的主要材料是什么呢？它又具有怎樣的特性來保證水質(zhì)的安全性和運輸?shù)陌踩阅?？它就?**要來介紹的主體—球墨鑄鐵管，下面小編就對于什么是球墨鑄鐵管做簡單介紹。首先，我們來了解一下什么是球墨鑄鐵管，球墨鑄鐵管是使用18號以上的鑄造鐵水在添加球化劑后，經(jīng)過離心球墨鑄鐵機高速離心后鑄造而成的管材，簡稱球管、球鐵管以及球墨鑄管等，其主要成分有碳、硅、錳、硫、磷和鎂等。球墨鑄鐵管也是自來水管道的理想選材，主要用途自然是輸送自來水。在我國很多地區(qū)，球墨鑄鐵管在中、小口徑的管與管之間的聯(lián)接，主要采用承式或法蘭盤式接口方法；而且球墨鑄鐵，容許限制的轉(zhuǎn)角必須有***的抗震性和密封性。其次，我們必須要知道球墨鑄鐵管有什么樣的特點，顧名思義，球墨鑄鐵管是鑄鐵管中的一種，在質(zhì)量上要求鑄鐵管的球化等級控制為1-3級，即球化率不小于80%，所以球墨鑄鐵管材料本身的機械性就可以得到比較好的改善，從而具有鐵的本質(zhì)和鋼的性能。在退火后，球墨鑄鐵管金相組織為鐵素體加上少量的珠光體，使得具有機械性能良好。阿克蘇給水球墨鑄鐵管便宜。頭屯河區(qū)球墨鑄鐵管公司哪家強</p><p
