球墨鑄鐵管是鑄鐵的一種，是一種鐵、碳和硅的合金。球墨鑄鐵中石墨是以球狀形式存在的，一通常般石墨的大小為6-7級，質(zhì)量上要求鑄管的球化等級控制為1-3級（球化率≥百分之八十），所以材料本身的機械性能取得了較好的改善，具有鐵的本質(zhì)，鋼的性能，廈門球墨鑄鐵管管件。退火后的球墨鑄鐵管，其金相**為鐵素體加少量珠光體，機械性能較好。球墨鑄鐵管主要稱之為離心球墨鑄鐵管，它具有鐵的本質(zhì)、鋼的性能，廈門球墨鑄鐵管管件，防腐性能好、延展性能好，密封效果好，安裝簡單、主要用于市政、工礦企業(yè)給水、輸氣，廈門球墨鑄鐵管管件,輸油等。是供水管材的理想選擇，具有很高的性價比。

承插連接，承插連接的方法是，對于球墨鑄鐵管確保連接位置為承口（假如不是，則用雙承套管，使得插口端轉(zhuǎn)換為承口端），鋼管端在其承口外徑焊接一層額外的鋼板，使得鋼管的外徑確保與球墨鑄鐵管外徑相同。之后插入球墨鑄鐵管的承口進行安裝。承插連接的優(yōu)勢是不存在螺栓埋地的腐蝕情況。但是對于大口徑管道，鋼管的壁厚較薄，同時鋼管是從井室中伸出的情況下，可能出現(xiàn)由于井室沉降，導(dǎo)致鋼管經(jīng)向變形過大，從而有接口漏水的狀況。

球墨鑄鐵是通過球化和孕育處理取得球狀石墨，地提高了鑄鐵的機械性能，特別是提高了塑性與韌性，從而取得比碳鋼還高的強度。球墨鑄鐵是二十世紀五十年代發(fā)展起來的一種**度鑄鐵材料，其綜合性能接近于鋼，正是基于優(yōu)良的性能，它已成功地用于鑄造一些受力復(fù)雜，強度、韌性以及耐磨性要求較高的零件。所謂的“以鐵代鋼”，主要就是指球墨鑄鐵。<span
