style="text-indent:25px">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(jí)，質(zhì)量上要求鑄管的球化等級(jí)控制為1-3級(jí)（球化率≥百分之八十），所以材料本身的機(jī)械性能取得了較好的改善，具有鐵的本質(zhì)，鋼的性能。退火后的球墨鑄鐵管，其金相**為鐵素體加少量珠光體，機(jī)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，防腐性能好、延展性能好，密封效果好，安裝簡(jiǎn)單、主要用于市政、工礦企業(yè)給水、輸氣,輸油等。是供水管材的理想選擇，具有很高的性價(jià)比。</p><p style="text-indent:25px">作為鑄鐵管中應(yīng)用十分廣的一款鐵管，球墨鑄鐵給水管是一款輕度高、管壁薄，同時(shí)具備耐腐蝕以及抗震性能的鑄鐵管。與傳統(tǒng)的鑄鐵管不同，其有著一定的延伸率以及偏轉(zhuǎn)角，因此在一定程度上我們可以將其理解成具備了生鐵管和鋼管材質(zhì)的優(yōu)點(diǎn)，但是也避免了鐵和鋼的缺點(diǎn)的一種鑄鐵管類型。和所有的工業(yè)配件一樣，其作為一種工業(yè)管件，也有著嚴(yán)格的規(guī)格標(biāo)準(zhǔn)，其中，比較常見(jiàn)的就是公稱直徑為80mm以及100mm的球墨鑄鐵給水管，其外徑一般比比直徑多十公分，而壁厚也*為6mm左右，在300mm的公稱直徑基礎(chǔ)之上，其規(guī)格就以10mm的直徑長(zhǎng)度遞增，共有二十余種球墨鑄鐵給水管規(guī)格。鑄鐵管我們需要了解哪些方面？</p><div

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(pán)接口，從而實(shí)現(xiàn)標(biāo)準(zhǔn)對(duì)接。盤(pán)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(pán)接口，只需與對(duì)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*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(shì)是，如果直接埋地，螺栓腐蝕風(fēng)險(xiǎn)較大，將來(lái)可能出現(xiàn)接口漏水等問(wèn)題，有的設(shè)計(jì)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。球墨鑄鐵管為什么受到大家的喜愛(ài)？廈門(mén)離心球墨鑄鐵管購(gòu)買(mǎi)</p><p
