螺(luo)旋管(guan)也稱螺(luo)旋鋼(gang)(gang)管(guan)或(huo)螺(luo)旋焊管(guan)，是(shi)將低碳素結(jie)構鋼(gang)(gang)或(huo)低合金結(jie)構鋼(gang)(gang)鋼(gang)(gang)帶按一定(ding)的(de)(de)螺(luo)旋線的(de)(de)角度（叫成(cheng)型(xing)角）卷(juan)成(cheng)管(guan)坯(pi)，然后將管(guan)縫焊接起來制(zhi)成(cheng)的(de)(de)，它(ta)可以用較窄(zhai)的(de)(de)帶鋼(gang)(gang)出產大直徑的(de)(de)鋼(gang)(gang)管(guan)。

       不銹鋼沖孔螺旋管的特(te)征：表面光滑沒(mei)有毛刺，焊縫均(jun)勻美麗，圓度(du)高，抗壓(ya)能力強，可沖壓(ya)多種孔(kong)(kong)(kong)(kong)型，如橋型孔(kong)(kong)(kong)(kong)、圓孔(kong)(kong)(kong)(kong)、方(fang)孔(kong)(kong)(kong)(kong)、長條孔(kong)(kong)(kong)(kong)等孔(kong)(kong)(kong)(kong)型，其他特(te)別孔(kong)(kong)(kong)(kong)型可根據用戶需(xu)求加工(gong)定做。

       不銹鋼沖孔螺旋管(guan)(guan)的(de)用途：廣泛用于石油(you)采油(you)、化工、污(wu)水處(chu)理、凈化水處(chu)理裝(zhuang)置、室內裝(zhuang)飾(shi)等，可(ke)用于石油(you)防沙管(guan)(guan)，也可(ke)作為濾芯骨(gu)架，支撐力大，圓度高，直(zhi)度好，外形尺寸、過濾精度、可(ke)根據客戶(hu)實際需要加工定制。

       不銹(xiu)鋼(gang)沖(chong)(chong)孔(kong)(kong)螺(luo)(luo)旋管的制作工(gong)藝：根(gen)據客(ke)戶(hu)要求將(jiang)相對應板帶沖(chong)(chong)孔(kong)(kong)；將(jiang)沖(chong)(chong)孔(kong)(kong)成(cheng)型(xing)的板帶按螺(luo)(luo)旋狀彎曲成(cheng)形，進(jin)行(xing)氬弧(hu)焊(han)焊(han)接(jie)；將(jiang)焊(han)接(jie)成(cheng)型(xing)的沖(chong)(chong)孔(kong)(kong)螺(luo)(luo)旋管進(jin)行(xing)表面打(da)磨處(chu)理；進(jin)一步進(jin)行(xing)表面拋光處(chu)理成(cheng)型(xing)。
