球墨鑄鐵管由于采用承插口連接，而鋼管通常采用焊接，并且兩者管道外徑與內(nèi)徑均不一致，因此需要特別的方法進行連接操作。目前常用的方法主要有以下兩種：法蘭連接?，此種方法為通用連接方法，廈門球墨鑄鐵管生產(chǎn)，此種方法原理是球墨鑄鐵管和鋼管均轉(zhuǎn)換為法蘭盤接口，因而實現(xiàn)標準對接。盤承短管，管件的承口或插口可以與正常管道相連，從而使得管線轉(zhuǎn)換為法蘭盤接口，廈門球墨鑄鐵管生產(chǎn)，只需與對應(yīng)的鋼制法蘭進行連接即可，廈門球墨鑄鐵管生產(chǎn)。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。

PE管的優(yōu)點：PE管具有良好的耐腐蝕性其抗無機物性能比金屬管強得多，在埋地敷設(shè)時不需要防腐，施工方便。小口徑PE管在性能價格比上優(yōu)于鋼管和球墨鑄鐵管。 PE管得缺點：苯、汽油、四氯化碳等有機溶劑對聚乙烯有一定得影響。有機溶劑如果滲入聚乙烯內(nèi)，會出現(xiàn)溶脹現(xiàn)象，其物理性能就下降，其耐壓性、耐溫度變化性能較差。廈門常達管業(yè)有限公司成立于2015年4月，座落于美麗的廈門，主營銷售不銹鋼管、PSP鋼塑復(fù)合壓力管、離心球墨鑄鐵管及配套管件、鑄造制品等相關(guān)業(yè)務(wù)。公司為客戶提供***的球墨鑄鐵管道系統(tǒng)，和各大管道品牌有著良好而深遠的合作，擁有豐富的產(chǎn)品種類，能為客戶提供品種齊全的管道及管件。關(guān)于球墨鑄鐵管我們應(yīng)該知道哪些方面？</p><div
