給水球墨鑄鐵管和排水球墨鑄鐵管的材質(zhì)為灰鑄鐵，由于給水球墨鑄鐵管需要承受壓力，常用HPT200,HT250灰鑄鐵，排水球墨鑄鐵管常用HT150以下的灰球墨鑄鐵管，給水球墨鑄鐵管都采用離心澆筑，鐵管外表光滑，如是承插式球墨鑄鐵管，則承**深，管壁也較厚，單根管長度為6米。排水球墨鑄鐵管有些采用立模澆注，或小型離心澆注機(jī)鑄造，廈門新興球墨鑄鐵管廠，鐵管外表較粗糙，單根管長度為3米，承口較淺，管壁較薄，給水球墨鑄鐵管分為工作壓力0.45MPA的低壓管，0.75MPA的中壓管，1.0MPA的高壓管，廈門新興球墨鑄鐵管廠，出廠前都需要按規(guī)范進(jìn)行水壓試驗，合格后方可出廠，廈門新興球墨鑄鐵管廠，排水球墨鑄鐵管只作外觀檢查和敲一敲聽音檢查，無氣孔，裂縫和破損音響為合格。

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(jìn)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，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(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)行連接即可。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。

對球墨鑄鐵管自身，在一定溫度的危害并非挺大，球墨鑄鐵件具備優(yōu)良的延展性和抗壓強度，延伸率好，球墨鑄鐵管在較低的溫度下還可以運作優(yōu)良。防止球鐵鑄造件裂痕關(guān)鍵是流體力學(xué)物質(zhì)中球墨鑄鐵管，假如流體力學(xué)的零界點較低可適度加上混凝土防凍劑，還可以為球墨鑄鐵管開展適度的調(diào)質(zhì)處理，它能在冬天低溫縫隙的防止。球墨鑄鐵鑄造件的挑選也是一個對策，挑選一個優(yōu)良的低溫冷藏原材料的球墨鑄鐵件制造，在制造高新技術(shù)對策，使球墨鑄鐵在低溫，低溫和高耐磨球墨鑄鐵鍛造成本費是十分貴的。

管道的埋設(shè)深度應(yīng)根據(jù)冰凍程度、外部荷載與其它管道交叉等因素確定。在通常情況下，埋設(shè)深度可在冰凍線以下0.2米處，并符合如下條件：當(dāng)管徑大于100mm時，管頂小埋深為1.20米。設(shè)計溝槽底寬通常為管外徑加0.5米，并根據(jù)土質(zhì)狀況，確定開挖坡度（i）球墨鑄鐵管與其它管材一樣，均勻流的沿程水頭損失為hf=λ/dv2/2g，所不同的只是“λ”（水力摩阻系數(shù)），即水頭損失可按原鑄鐵管局部阻力損失計算。球墨鑄鐵管的出現(xiàn)為我國供水事業(yè)提供了一種性能優(yōu)良的新型管材。為了在工程中更好的應(yīng)用球墨鑄鐵管，設(shè)計與施工人員應(yīng)熟悉球墨鑄鐵管的特性，不斷地發(fā)現(xiàn)問題并加以解決，使設(shè)計更加合理、施工更加規(guī)范，使新型管材在供水工程中發(fā)揮更大的作用。
