沖(chong)(chong)孔(kong)(kong)管(guan)，沖(chong)(chong)孔(kong)(kong)螺旋(xuan)管(guan)，螺旋(xuan)沖(chong)(chong)孔(kong)(kong)不銹(xiu)鋼(gang)(gang)管(guan)，不銹(xiu)鋼(gang)(gang)過濾(lv)管(guan)，不銹(xiu)鋼(gang)(gang)沖(chong)(chong)孔(kong)(kong)管(guan)，石(shi)油防砂管(guan)是(shi)的(de)(de)首要產品，沖(chong)(chong)孔(kong)(kong)管(guan) 的(de)(de)用(yong)處是(shi)沖(chong)(chong)孔(kong)(kong)管(guan)廣泛用(yong)于：石(shi)油 采油、化工、污水處理(li)(li)、凈化水處理(li)(li)設備(bei)等(deng)環保范疇原料(liao)碳(tan)鋼(gang)(gang)，最長達80m.螺旋(xuan)焊(han)管(guan)有(you)單面焊(han)和雙(shuang)面焊(han)。

    工藝流程： 開卷(juan)--上卷(juan)--校平--對接(jie)焊(han)(han)--銑邊--成(cheng)型--內焊(han)(han)--外(wai)焊(han)(han)--切管(guan)(guan)--破(po)口--后續焊(han)(han)-實驗外(wai)形尺寸：鋼管(guan)(guan)外(wai)徑、壁(bi)厚、橢圓度(du)、彎曲度(du)、管(guan)(guan)端筆直度(du)、可根(gen)據客戶要(yao)求加工出產用處(chu)：首(shou)要(yao)用于石油(you)、天然氣的(de)運送(song)管(guan)(guan)線。

    螺旋(xuan)管(guan)(guan)特色：直縫(feng)焊(han)(han)(han)管(guan)(guan)出(chu)產工藝簡略，出(chu)產效率(lv)高，成本低，開展較快。螺旋(xuan)焊(han)(han)(han)管(guan)(guan)的強度(du)(du)一般比直縫(feng)焊(han)(han)(han)管(guan)(guan)高，能(neng)用較窄(zhai)的坯(pi)料(liao)出(chu)產管(guan)(guan)徑(jing)較大(da)的焊(han)(han)(han)管(guan)(guan)，還可以用相同(tong)(tong)寬度(du)(du)的坯(pi)料(liao)出(chu)產管(guan)(guan)徑(jing)不同(tong)(tong)的焊(han)(han)(han)管(guan)(guan)。可是與(yu)相同(tong)(tong)長度(du)(du)的直縫(feng)管(guan)(guan)比較，焊(han)(han)(han)縫(feng)長度(du)(du)添加30~100百(bai)分(fen)之(zhi)。

    并(bing)且出產(chan)速度較低。因而，較小口徑的焊管(guan)(guan)(guan)(guan)大(da)都選用直縫焊，大(da)口徑焊管(guan)(guan)(guan)(guan)則大(da)多選用螺(luo)旋(xuan)焊。不(bu)銹(xiu)(xiu)鋼(gang)(gang)焊管(guan)(guan)(guan)(guan)分類：銹(xiu)(xiu)鋼(gang)(gang)圓管(guan)(guan)(guan)(guan)： 外(wai)徑0.5mm-1201mm、不(bu)銹(xiu)(xiu)鋼(gang)(gang)方管(guan)(guan)(guan)(guan)： 2×2-351×351mm;不(bu)銹(xiu)(xiu)鋼(gang)(gang)矩(ju)管(guan)(guan)(guan)(guan)： 2×3-501×701mm;、不(bu)銹(xiu)(xiu)鋼(gang)(gang)橢(tuo)圓管(guan)(guan)(guan)(guan)效果產(chan)品(pin)用處：裝修用管(guan)(guan)(guan)(guan)，工業(ye)用管(guan)(guan)(guan)(guan)，機(ji)械結(jie)構(gou)用管(guan)(guan)(guan)(guan)，流體用管(guan)(guan)(guan)(guan)，氣體運送用管(guan)(guan)(guan)(guan)。
