螺旋焊橋式(shi)濾水管,用于石(shi)油(you)鉆(zhan)井(jing)(jing)、深水(shui)鉆(zhan)井(jing)(jing)行(xing)業(ye)的(de)(de)井(jing)(jing)體控(kong)砂(sha)用的(de)(de)過濾(lv)管(guan)(guan)(guan)。目(mu)前，石(shi)油(you)鉆(zhan)井(jing)(jing)、深水(shui)鉆(zhan)井(jing)(jing)行(xing)業(ye)井(jing)(jing)體控(kong)砂(sha)采用的(de)(de)濾(lv)管(guan)(guan)(guan)為直焊縫(feng)過濾(lv)管(guan)(guan)(guan)，由于直焊縫(feng)濾(lv)管(guan)(guan)(guan)的(de)(de)制(zhi)造(zao)工(gong)藝及結構(gou)特性(xing)，造(zao)成(cheng)直焊縫(feng)濾(lv)管(guan)(guan)(guan)的(de)(de)圓度(du)誤差、軸線(xian)直線(xian)度(du)誤差大，擾度(du)大，剛性(xing)差。直縫(feng)焊濾(lv)水(shui)管(guan)(guan)(guan)因其焊縫(feng)為直線(xian)，常常會內應(ying)力分布不均，造(zao)成(cheng)濾(lv)管(guan)(guan)(guan)易彎扭(niu)變形，濾(lv)管(guan)(guan)(guan)尺寸一致差。  

鑄鐵濾水管的材質一般都是Q235B材質，這種材質的(de)鋼(gang)材含碳適中，綜合性(xing)能(neng)較好(hao)(hao)，強度(du)、塑性(xing)和(he)焊接等性(xing)能(neng)得到(dao)較好(hao)(hao)配合，用途廣泛(fan)。它的(de)壽(shou)命(ming)關乎到(dao)一口(kou)井(jing)的(de)壽(shou)命(ming)，鉆井(jing)要用到(dao)很多的(de)人力物(wu)力和(he)財力，因(yin)此其防腐問題對于(yu)一口(kou)井(jing)的(de)使用壽(shou)命(ming)有(you)著(zhu)極大地(di)影響。
