　　友發(fa)鋼(gang)(gang)管生產(chan)工藝(yi)流(liu)程：是(shi)以(yi)熱軋帶鋼(gang)(gang)板卷為原料,常常溫(wen)擠壓加(jia)工,以(yi)全自動雙絲兩面電弧焊(han)加(jia)工工藝(yi)電焊(han)焊(han)接而成的螺旋式(shi)縫(feng)無縫(feng)鋼(gang)(gang)管。

　　1、原(yuan)料即熱軋帶鋼卷，焊條，助焊劑。在資金(jin)投入前都需要通過嚴謹的理化檢(jian)測。

　　2、熱軋帶鋼首尾連(lian)接，選用拉絲或雙絲電(dian)弧焊(han)接，在疊成(cheng)無(wu)縫(feng)鋼管后使用自動電(dian)弧焊(han)焊(han)補。

　　3、成(cheng)形前，熱軋帶鋼通過矯平、剪邊、刨邊，表層清除運(yun)輸和(he)予(yu)彎(wan)邊解決。

　　4、選用電(dian)接(jie)點壓力表操縱皮帶輸(shu)送機兩側壓下液壓缸(gang)的工作(zuo)壓力，保證了熱軋帶鋼的穩定運輸(shu)。

　　5、選用外控(kong)或內部控(kong)制輥式成形。

　　6、選用焊(han)接(jie)空(kong)隙(xi)操(cao)縱設備來確保焊(han)接(jie)空(kong)隙(xi)達到電焊(han)焊(han)接(jie)規定，管經(jing)，錯邊量(liang)和(he)焊(han)接(jie)空(kong)隙(xi)都獲(huo)得嚴謹的操(cao)縱。

　　友發鋼(gang)管(guan)是以熱軋帶(dai)鋼(gang)板(ban)卷為原(yuan)料,常常溫擠(ji)壓加工,以全自(zi)動雙絲兩面電弧焊(han)(han)(han)加工工藝電焊(han)(han)(han)焊(han)(han)(han)接而成的(de)(de)螺旋(xuan)式(shi)(shi)縫(feng)無(wu)縫(feng)鋼(gang)管(guan).選用焊(han)(han)(han)接空(kong)(kong)隙操(cao)縱(zong)設備來確(que)保焊(han)(han)(han)接空(kong)(kong)隙達到電焊(han)(han)(han)焊(han)(han)(han)接規定(ding)(ding)，管(guan)經(jing)，錯邊量和(he)焊(han)(han)(han)接空(kong)(kong)隙都獲得嚴(yan)謹的(de)(de)操(cao)縱(zong)。焊(han)(han)(han)接上(shang)面有持續聲波頻率探(tan)傷檢測標識的(de)(de)位置，通(tong)過(guo)(guo)(guo)(guo)手(shou)動式(shi)(shi)超聲和(he)X射(she)線(xian)復(fu)診，如確(que)實(shi)(shi)有缺點，通(tong)過(guo)(guo)(guo)(guo)修復(fu)后(hou)，再度通(tong)過(guo)(guo)(guo)(guo)高質量檢測，直到確(que)定(ding)(ding)問題早已(yi)清除。每根無(wu)縫(feng)鋼(gang)管(guan)通(tong)過(guo)(guo)(guo)(guo)靜水壓力(li)實(shi)(shi)驗，工作(zuo)壓力(li)選用切向密封(feng)性。實(shi)(shi)驗工作(zuo)壓力(li)和(he)時間都由無(wu)縫(feng)鋼(gang)管(guan)壓力(li)微(wei)型(xing)機(ji)檢驗設備嚴(yan)控。實(shi)(shi)驗主要參數全自(zi)動打印(yin)記錄。成形前，熱軋帶(dai)鋼(gang)通(tong)過(guo)(guo)(guo)(guo)矯平、剪邊、刨(bao)邊，表層清除運(yun)輸和(he)予彎邊解決。
