一、球墨鑄鐵管是鋼管嗎

球(qiu)(qiu)(qiu)墨鑄(zhu)鐵(tie)管(guan)(guan)(guan)(guan)(guan)(guan)不(bu)是鋼管(guan)(guan)(guan)(guan)(guan)(guan)。球(qiu)(qiu)(qiu)墨鑄(zhu)鐵(tie)管(guan)(guan)(guan)(guan)(guan)(guan)也被(bei)成為鑄(zhu)鐵(tie)鋼管(guan)(guan)(guan)(guan)(guan)(guan)，但其(qi)本質(zhi)并不(bu)是鋼管(guan)(guan)(guan)(guan)(guan)(guan)，因(yin)球(qiu)(qiu)(qiu)墨鑄(zhu)鐵(tie)管(guan)(guan)(guan)(guan)(guan)(guan)有(you)鐵(tie)的(de)本質(zhi)、鋼的(de)性能(neng)，所以有(you)此叫法(fa)。球(qiu)(qiu)(qiu)墨鑄(zhu)鐵(tie)管(guan)(guan)(guan)(guan)(guan)(guan)是指(zhi)使用(yong)18號以上的(de)鑄(zhu)造鐵(tie)水經添(tian)加(jia)球(qiu)(qiu)(qiu)化劑后，經過(guo)離心(xin)球(qiu)(qiu)(qiu)墨鑄(zhu)鐵(tie)機高(gao)速(su)離心(xin)鑄(zhu)造成的(de)管(guan)(guan)(guan)(guan)(guan)(guan)材，簡稱為球(qiu)(qiu)(qiu)管(guan)(guan)(guan)(guan)(guan)(guan)、球(qiu)(qiu)(qiu)鐵(tie)管(guan)(guan)(guan)(guan)(guan)(guan)和球(qiu)(qiu)(qiu)墨鑄(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)等。主要用(yong)于自(zi)來(lai)水的(de)輸(shu)送，是自(zi)來(lai)水管(guan)(guan)(guan)(guan)(guan)(guan)道理想的(de)選(xuan)擇用(yong)料。

1、用途不同

鑄鐵管(guan)(guan)(guan)(guan)適(shi)用于(yu)新建(jian)、擴建(jian)、改建(jian)的民用和(he)工(gong)業建(jian)筑室內及卡(ka)箍式連接的生活排水管(guan)(guan)(guan)(guan)、雨水管(guan)(guan)(guan)(guan)、工(gong)業廢水管(guan)(guan)(guan)(guan)和(he)雨滴管(guan)(guan)(guan)(guan)。鋼管(guan)(guan)(guan)(guan)用于(yu)輸送(song)流體(ti)和(he)粉末固(gu)體(ti)，交換熱能，制造機(ji)械(xie)(xie)零件和(he)容(rong)器(qi)，是一種經濟型鋼。采用鋼管(guan)(guan)(guan)(guan)制造建(jian)筑結構的空(kong)間桁架、立柱和(he)機(ji)械(xie)(xie)支架，可以減輕重量，節約20-40%的金屬，實現工(gong)業化機(ji)械(xie)(xie)化施工(gong)。

2、特點不同

鑄鐵管具有操作安全可靠、損壞率低、施工維護方便、防腐性能優良等優點。鋼管具有生產工藝簡單，生產效率高，品種規格多，設備投資少；無縫鋼管與圓鋼等實心鋼相比，是一種具有相同抗彎、抗扭強度的經濟型鋼。

3、分類不同

鑄鐵管可分為三類：直管、管件及附件。從接口形式上可分為W型柔性鑄鐵排水管、B型柔性鑄鐵排水管和A型柔性鑄鐵排水管。從材質上看：球墨鑄鐵排水管、灰鑄(zhu)鐵(tie)排水(shui)管(guan)(guan)(guan)(guan)(guan)。根據生(sheng)產(chan)方法，鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)可分為(wei)無(wu)(wu)縫鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)和(he)無(wu)(wu)縫鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)。無(wu)(wu)縫鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)簡稱(cheng)直縫鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)。鑄(zhu)鐵(tie)管(guan)(guan)(guan)(guan)(guan)適(shi)用于新建(jian)(jian)、擴建(jian)(jian)和(he)改建(jian)(jian)的(de)(de)民(min)用和(he)工業(ye)建(jian)(jian)筑室內、外(wai)管(guan)(guan)(guan)(guan)(guan)徑為(wei)DN50mm~DN300mm、內壓不大于0.3MPa的(de)(de)承(cheng)插式(shi)和(he)卡(ka)箍式(shi)連(lian)接(jie)的(de)(de)灰口鑄(zhu)鐵(tie)管(guan)(guan)(guan)(guan)(guan)及其配套管(guan)(guan)(guan)(guan)(guan)件的(de)(de)生(sheng)活排水(shui)管(guan)(guan)(guan)(guan)(guan)道、雨水(shui)管(guan)(guan)(guan)(guan)(guan)道、無(wu)(wu)侵蝕作用的(de)(de)工業(ye)生(sheng)產(chan)廢水(shui)管(guan)(guan)(guan)(guan)(guan)道和(he)雨落管(guan)(guan)(guan)(guan)(guan)。鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)不僅(jin)用于輸送流體和(he)粉(fen)狀固體、交換(huan)熱能、制(zhi)造機械零件和(he)容器，它(ta)還是一種(zhong)經濟鋼(gang)(gang)(gang)材(cai)。
