style="text-indent:25px">球墨鑄鐵管基本上是利用在與我們的下水管道上的，目前社會中的人群基本都在陸陸續(xù)續(xù)的換上了球墨鑄鐵管的使用情況，把普通的塑料管道都統(tǒng)統(tǒng)換掉了。球墨鑄鐵管主要就是由它堅硬的體現(xiàn)，可以起到一種很穩(wěn)定的作用，可以很好的穩(wěn)固我們的樓房，讓我們住的更加安穩(wěn)，并且也是有著很厚的厚度，全都是由專門的鐵所打造的，管道的內(nèi)部有著很光滑的內(nèi)體，能夠很好的疏通水和垃圾。與PE管材相比，從安裝時間上，球墨管比PE管安裝更簡單快捷，且安裝后內(nèi)外承壓力更好。</p><p> 球墨鑄鐵是屬于脆性材料，首先，鑄鐵意味著含碳量大于百分之二點(diǎn)一（球墨鑄鐵含碳量在百分之三點(diǎn)五到百分之三點(diǎn)九，金相**是：鐵素體+珠光體），含碳量高，其硬度肯定高，其次，對球墨進(jìn)行球化處理，意味著金屬微粒尺寸變小，這同樣也會提高材料強(qiáng)度，硬度。所以一般而言球墨鑄鐵的硬度很大（肯定高于一般的鋼）。但是有時對一些球墨鑄鐵做沖擊韌性實驗，研究其斷口，斷口形貌表現(xiàn)韌窩斷口，說明其為韌性斷裂。鑒于研究上的習(xí)慣，球墨鑄鐵我們習(xí)慣稱之為脆性材料。

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(jìn)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。

style="text-indent:25px">法蘭連接，此種方法為通用連接方法，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，從而實現(xiàn)標(biāo)準(zhǔn)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，只需與對應(yīng)的鋼制法蘭進(jìn)行連接就可以。此種方法特點(diǎn)是，連接方式比較通用，法蘭的制作為標(biāo)準(zhǔn)件，保證連接的穩(wěn)定性。需要注意的是，雙方的法蘭不僅需要公稱值一致，PN值也應(yīng)一致才能連接。法蘭連接的劣勢是，如果直接埋地，螺栓腐蝕風(fēng)險較大，將來可能出現(xiàn)接口漏水等問題，有的設(shè)計規(guī)范也要求螺栓不能直接埋地。此外法蘭連接由于采用螺栓緊固確保密封效果，人工操作的影響較大。廈門球墨鑄鐵管銷售</p><p
