一、球墨鑄鐵管是鋼管嗎

球(qiu)(qiu)墨鑄鐵(tie)(tie)管(guan)不是(shi)(shi)鋼管(guan)。球(qiu)(qiu)墨鑄鐵(tie)(tie)管(guan)也被成為鑄鐵(tie)(tie)鋼管(guan)，但(dan)其本質并不是(shi)(shi)鋼管(guan)，因球(qiu)(qiu)墨鑄鐵(tie)(tie)管(guan)有鐵(tie)(tie)的本質、鋼的性能(neng)，所以有此叫法。球(qiu)(qiu)墨鑄鐵(tie)(tie)管(guan)是(shi)(shi)指(zhi)使(shi)用(yong)(yong)18號以上的鑄造鐵(tie)(tie)水經(jing)添加球(qiu)(qiu)化劑后(hou)，經(jing)過離心球(qiu)(qiu)墨鑄鐵(tie)(tie)機高速(su)離心鑄造成的管(guan)材，簡(jian)稱為球(qiu)(qiu)管(guan)、球(qiu)(qiu)鐵(tie)(tie)管(guan)和球(qiu)(qiu)墨鑄管(guan)等。主要用(yong)(yong)于自來(lai)水的輸送(song)，是(shi)(shi)自來(lai)水管(guan)道理(li)想的選(xuan)擇用(yong)(yong)料。

1、用途不同

鑄(zhu)鐵管(guan)(guan)(guan)適用(yong)(yong)于(yu)新建(jian)(jian)、擴建(jian)(jian)、改建(jian)(jian)的(de)(de)民用(yong)(yong)和(he)工(gong)(gong)業(ye)建(jian)(jian)筑室內及(ji)卡箍式(shi)連接的(de)(de)生活(huo)排水管(guan)(guan)(guan)、雨水管(guan)(guan)(guan)、工(gong)(gong)業(ye)廢水管(guan)(guan)(guan)和(he)雨滴(di)管(guan)(guan)(guan)。鋼(gang)管(guan)(guan)(guan)用(yong)(yong)于(yu)輸送流體和(he)粉末固體，交換熱能(neng)，制(zhi)造機械(xie)零(ling)件和(he)容(rong)器，是(shi)一種經濟型鋼(gang)。采用(yong)(yong)鋼(gang)管(guan)(guan)(guan)制(zhi)造建(jian)(jian)筑結(jie)構的(de)(de)空(kong)間(jian)桁架、立柱和(he)機械(xie)支架，可以減輕重(zhong)量，節約20-40%的(de)(de)金屬，實現工(gong)(gong)業(ye)化機械(xie)化施工(gong)(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(gang)等實心鋼(gang)相比，是一種具有(you)相同抗彎、抗扭強度(du)的經濟型(xing)鋼(gang)。

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、灰鑄鐵排(pai)水管(guan)(guan)(guan)(guan)(guan)。根據(ju)生產(chan)方法，鋼(gang)管(guan)(guan)(guan)(guan)(guan)可分為(wei)無(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)和(he)無(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)。無(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)簡稱直縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)。鑄鐵管(guan)(guan)(guan)(guan)(guan)適用(yong)于新(xin)建(jian)、擴建(jian)和(he)改(gai)建(jian)的(de)民用(yong)和(he)工業(ye)(ye)建(jian)筑室內、外管(guan)(guan)(guan)(guan)(guan)徑為(wei)DN50mm~DN300mm、內壓(ya)不大于0.3MPa的(de)承插式(shi)(shi)和(he)卡(ka)箍式(shi)(shi)連接的(de)灰口鑄鐵管(guan)(guan)(guan)(guan)(guan)及其配套管(guan)(guan)(guan)(guan)(guan)件的(de)生活排(pai)水管(guan)(guan)(guan)(guan)(guan)道(dao)、雨水管(guan)(guan)(guan)(guan)(guan)道(dao)、無(wu)侵(qin)蝕作用(yong)的(de)工業(ye)(ye)生產(chan)廢(fei)水管(guan)(guan)(guan)(guan)(guan)道(dao)和(he)雨落管(guan)(guan)(guan)(guan)(guan)。鋼(gang)管(guan)(guan)(guan)(guan)(guan)不僅用(yong)于輸(shu)送流(liu)體和(he)粉(fen)狀固體、交換熱能、制造機械(xie)零件和(he)容(rong)器，它還是一種經濟鋼(gang)材。
