直縫焊(han)(han)管(guan)(guan),用熱軋或冷(leng)軋鋼(gang)板或鋼(gang)帶卷焊(han)(han)制成的(de)鋼(gang)管(guan)(guan)在焊(han)(han)接設備上進行直縫焊(han)(han)接得(de)到的(de)管(guan)(guan)子都叫直縫焊(han)(han)管(guan)(guan)。(由于鋼(gang)管(guan)(guan)的(de)焊(han)(han)接處成一條直線(xian)故(gu)而得(de)名)。
其中按照用途(tu)不同,又不同的(de)后道生產(chan)工序,.(大致(zhi)可分為腳(jiao)手(shou)架管(guan)(guan)(guan)(guan),流(liu)(liu)體管(guan)(guan)(guan)(guan),電線(xian)套管(guan)(guan)(guan)(guan),支架管(guan)(guan)(guan)(guan),護欄管(guan)(guan)(guan)(guan)等幾種(zhong)(zhong))。直縫焊(han)(han)(han)管(guan)(guan)(guan)(guan)標準(zhun) GB/T3091-2008而(er)低壓流(liu)(liu)體焊(han)(han)(han)管(guan)(guan)(guan)(guan)是直縫焊(han)(han)(han)管(guan)(guan)(guan)(guan)的(de)一種(zhong)(zhong),一般用水(shui),煤(mei)氣的(de)輸送, 在(zai)焊(han)(han)(han)接(jie)完畢(bi)后比普通(tong)(tong)焊(han)(han)(han)管(guan)(guan)(guan)(guan)多加(jia)以(yi)一道水(shui)壓測試,當前(qian)低壓流(liu)(liu)體管(guan)(guan)(guan)(guan)比普通(tong)(tong)直縫焊(han)(han)(han)管(guan)(guan)(guan)(guan)價格高出一點(按當前(qian)的(de)市場價來說,大概(gai)高出80元左右) 例如:焊(han)(han)(han)接(jie)鋼管(guan)(guan)(guan)(guan)流(liu)(liu)體管(guan)(guan)(guan)(guan)1寸(DN25)(就是Φ33.5*3.25) 價格大概(gai)在(zai)4500每噸,而(er)普通(tong)(tong)直縫焊(han)(han)(han)管(guan)(guan)(guan)(guan)在(zai)4400左右。
