直縫鋼管

直(zhi)(zhi)縫鋼(gang)管(guan)(guan)(guan)是焊(han)(han)縫與(yu)鋼(gang)管(guan)(guan)(guan)縱向平(ping)行的鋼(gang)管(guan)(guan)(guan),通常分(fen)為公制電焊(han)(han)鋼(gang)管(guan)(guan)(guan)、電焊(han)(han)薄壁管(guan)(guan)(guan)、變壓器冷卻(que)油管(guan)(guan)(guan)等等。直(zhi)(zhi)縫焊(han)(han)管(guan)(guan)(guan)生產工藝簡單,生產效率(lv)高,成(cheng)本低,發展較快(kuai)。


螺旋(xuan)焊管(guan)(guan)的(de)(de)強度(du)一般比直縫焊管(guan)(guan)高,能用較(jiao)窄(zhai)的(de)(de)坯料生產管(guan)(guan)徑較(jiao)大的(de)(de)焊管(guan)(guan),還可以用同(tong)樣寬度(du)的(de)(de)坯料生產管(guan)(guan)徑不同(tong)的(de)(de)焊管(guan)(guan)。但是與相同(tong)長度(du)的(de)(de)直縫管(guan)(guan)相比,焊縫長度(du)增(zeng)加30~100%,而且生產速度(du)較(jiao)低(di)。


直縫(feng)鋼(gang)管是一種(zhong)籠統得(de)叫法,方式用鋼(gang)帶生產,在高頻焊(han)接設備直縫(feng)焊(han)接的管子都叫直縫(feng)鋼(gang)管。(由于鋼(gang)管的焊(han)接處成一條直線故(gu)而得(de)名)。


其中按(an)(an)照用途不同,又(you)不同的后(hou)(hou)道生產工序.(大致可分為腳(jiao)手架管(guan)(guan)(guan),流體(ti)管(guan)(guan)(guan),電線(xian)套管(guan)(guan)(guan),支架管(guan)(guan)(guan),護欄管(guan)(guan)(guan)等(deng)幾種) 而低壓流體(ti)焊(han)(han)(han)(han)管(guan)(guan)(guan)是(shi)直縫焊(han)(han)(han)(han)管(guan)(guan)(guan)的一(yi)種,一(yi)般用水,煤氣的輸送,在焊(han)(han)(han)(han)接(jie)(jie)完畢后(hou)(hou)比(bi)普通焊(han)(han)(han)(han)管(guan)(guan)(guan)多加(jia)以一(yi)道水壓測試,故(gu)而低壓流體(ti)管(guan)(guan)(guan)比(bi)普通直縫焊(han)(han)(han)(han)管(guan)(guan)(guan)價格一(yi)般高(gao)出一(yi)點(按(an)(an)現在的市(shi)場價來說,大概高(gao)出80元(yuan)左右) 例如(ru):焊(han)(han)(han)(han)接(jie)(jie)鋼(gang)管(guan)(guan)(guan)流體(ti)1寸(DN25)(就(jiu)是(shi)Φ33.5*3.25) 焊(han)(han)(han)(han)接(jie)(jie)鋼(gang)管(guan)(guan)(guan):也(ye)叫(jiao)焊(han)(han)(han)(han)管(guan)(guan)(guan),是(shi)用鋼(gang)板或鋼(gang)帶經過彎曲成(cheng)(cheng)型,然后(hou)(hou)經焊(han)(han)(han)(han)接(jie)(jie)制(zhi)成(cheng)(cheng)。按(an)(an)焊(han)(han)(han)(han)縫形(xing)式分為直縫焊(han)(han)(han)(han)管(guan)(guan)(guan)和螺旋焊(han)(han)(han)(han)管(guan)(guan)(guan)。按(an)(an)用途又(you)分為一(yi)般焊(han)(han)(han)(han)管(guan)(guan)(guan)、鍍鋅焊(han)(han)(han)(han)管(guan)(guan)(guan)、吹氧焊(han)(han)(han)(han)管(guan)(guan)(guan)、電線(xian)套管(guan)(guan)(guan)、公制(zhi)焊(han)(han)(han)(han)管(guan)(guan)(guan)、托輥管(guan)(guan)(guan)、深(shen)井泵管(guan)(guan)(guan)、汽車用管(guan)(guan)(guan)、變壓器管(guan)(guan)(guan)、電焊(han)(han)(han)(han)薄壁管(guan)(guan)(guan)、電焊(han)(han)(han)(han)異(yi)型管(guan)(guan)(guan)和螺旋焊(han)(han)(han)(han)管(guan)(guan)(guan)。


一般焊管(guan)(guan)(guan):一般焊管(guan)(guan)(guan)用(yong)來輸送低壓(ya)流體。用(yong)Q195A、Q215A、Q235A鋼(gang)(gang)制造 。也(ye)可(ke)采用(yong)易于焊接的其它軟(ruan)鋼(gang)(gang)制造。鋼(gang)(gang)管(guan)(guan)(guan)要進行水壓(ya)、彎曲(qu)、壓(ya)扁(bian)等實驗(yan),對表面質量(liang)有一定要求(qiu),通(tong)常交(jiao)貨長度為4-10m,常要求(qiu)定尺(chi)(chi)(或倍尺(chi)(chi))交(jiao)貨。焊管(guan)(guan)(guan)的規格用(yong)公(gong)稱(cheng)口徑(jing) 表示(毫米或英(ying)寸(cun))公(gong)稱(cheng)口徑(jing)與實際不同,焊管(guan)(guan)(guan)按規定壁厚有普通(tong)鋼(gang)(gang)管(guan)(guan)(guan)和加厚鋼(gang)(gang)管(guan)(guan)(guan)兩(liang)種,鋼(gang)(gang)管(guan)(guan)(guan)按管(guan)(guan)(guan)端(duan)形式又(you)分(fen)帶螺紋和不帶螺紋兩(liang)種,為焊接鋼(gang)(gang)管(guan)(guan)(guan)尺(chi)(chi)寸(cun)。
