生產丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)所用(yong)(yong)到的(de)加熱(re)(re)(re)爐(lu)，所采(cai)用(yong)(yong)的(de)是環(huan)形(xing)加熱(re)(re)(re)爐(lu)，除了這(zhe)(zhe)種加熱(re)(re)(re)爐(lu)以(yi)外，還(huan)有(you)其(qi)(qi)(qi)他種類的(de)加熱(re)(re)(re)爐(lu)，根(gen)據制作丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)的(de)不(bu)同，在(zai)(zai)具體加熱(re)(re)(re)方式上(shang)也(ye)是有(you)差異(yi)的(de)，在(zai)(zai)熱(re)(re)(re)處理(li)完成之后，還(huan)需進(jin)行(xing)進(jin)一(yi)(yi)步(bu)(bu)的(de)加工(gong)，包括矯直，精整(zheng)和(he)檢(jian)(jian)驗(yan)這(zhe)(zhe)幾(ji)個步(bu)(bu)驟，這(zhe)(zhe)樣(yang)才能(neng)保證丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)在(zai)(zai)出(chu)場時的(de)質(zhi)量(liang)能(neng)保持在(zai)(zai) 水(shui)平，因此檢(jian)(jian)驗(yan)的(de)步(bu)(bu)驟必不(bu)可少。 丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)在(zai)(zai)出(chu)廠前都(dou)需要對其(qi)(qi)(qi)力(li)學(xue)性能(neng)進(jin)行(xing)考察，特別是對丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)的(de)抗拉強度(du)(du)、屈服點、斷后伸長率和(he)硬度(du)(du)指標進(jin)行(xing)考察，這(zhe)(zhe)樣(yang)才能(neng)保證丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)在(zai)(zai)出(chu)廠前能(neng)夠在(zai)(zai)質(zhi)量(liang)方面得到保證。根(gen)據具體使用(yong)(yong)領域的(de)差異(yi)，丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)在(zai)(zai)制作工(gong)藝上(shang)也(ye)有(you)一(yi)(yi)定(ding)的(de)區(qu)別，比較(jiao)常見的(de)有(you)合金結構和(he)碳素結構兩種。在(zai)(zai)管(guan)道運(yun)輸領域中，丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)的(de)利用(yong)(yong)率是很高的(de)，因為與(yu)其(qi)(qi)(qi)他類型的(de)運(yun)輸方式相比，管(guan)道運(yun)輸不(bu)但，而且造價(jia)比較(jiao)低，所以(yi)，對于丹(dan)(dan)(dan)(dan)東(dong)(dong)無(wu)(wu)縫(feng)鋼(gang)管(guan)產量(liang)的(de)需求自然也(ye)會比較(jiao)大(da)一(yi)(yi)些。
