單就種類上看，無縫鋼管的種類是比較多樣的，市面上，需求量較高的有熱擴無縫管和大口徑無縫管這兩種，通常會根據用途的差異，來選擇無縫鋼管的具體尺寸，至于長度和厚度的方面，都可以進行定制。

在(zai)中(zhong)國，比較著名的(de)無縫(feng)鋼(gang)管生產地，主要集中(zhong)在(zai)崇(chong)鋼(gang)、包(bao)鋼(gang)，無錫、山東、冶(ye)鋼(gang)、鞍(an)鋼(gang)等地，可以說(shuo)，需(xu)求量還(huan)是很大(da)的(de)。而在(zai)材質上，也(ye)會根據用途(tu)的(de)不(bu)同而略有差(cha)異。

如果將無(wu)(wu)縫(feng)(feng)管(guan)進(jin)行細致的劃(hua)分(fen)，可(ke)以(yi)被分(fen)為冷拔無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)，熱軋無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)、大口徑(jing)厚壁無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)，中(zhong)低壓鍋爐用無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)、輸送流體(ti)用無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)、結構用無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)、建筑用無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)等幾大系列，再根據具體(ti)的用途來進(jin)行選擇，不但(dan)簡(jian)單方(fang)便(bian)，同時這種有針(zhen)對性的管(guan)道材(cai)料(liao)，也能從一定程度上提升工作效率。

無(wu)縫鋼管因其用(yong)途不同的各種分類

無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)在各個領域有著不(bu)同的(de)(de)作用(yong)(yong)(yong)(yong)(yong)，具體(ti)幾大(da)分類如下1.結構(gou)用(yong)(yong)(yong)(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)：主要用(yong)(yong)(yong)(yong)(yong)于(yu)一般結構(gou)和(he)機(ji)械結構(gou)。2.輸送(song)流體(ti)用(yong)(yong)(yong)(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)：主要用(yong)(yong)(yong)(yong)(yong)于(yu)工程及(ji)大(da)型設備上輸送(song)流體(ti)管(guan)(guan)(guan)(guan)(guan)道(dao)3低(di)中壓鍋(guo)(guo)爐(lu)用(yong)(yong)(yong)(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)是(shi)用(yong)(yong)(yong)(yong)(yong)于(yu)制造各種結構(gou)低(di)中壓鍋(guo)(guo)爐(lu)過熱(re)(re)(re)(re)蒸汽管(guan)(guan)(guan)(guan)(guan)、沸水管(guan)(guan)(guan)(guan)(guan)及(ji)機(ji)車鍋(guo)(guo)爐(lu)用(yong)(yong)(yong)(yong)(yong)過熱(re)(re)(re)(re)蒸汽管(guan)(guan)(guan)(guan)(guan)、大(da)煙管(guan)(guan)(guan)(guan)(guan)、小煙管(guan)(guan)(guan)(guan)(guan)和(he)拱磚管(guan)(guan)(guan)(guan)(guan)用(yong)(yong)(yong)(yong)(yong)的(de)(de)碳(tan)素(su)(su)結構(gou)鋼(gang)(gang)(gang)熱(re)(re)(re)(re)軋(ya)和(he)冷拔(ba)（軋(ya)）無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)。4.高(gao)壓鍋(guo)(guo)爐(lu)用(yong)(yong)(yong)(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)是(shi)用(yong)(yong)(yong)(yong)(yong)于(yu)制造高(gao)壓及(ji)其以(yi)上壓力的(de)(de)水管(guan)(guan)(guan)(guan)(guan)鍋(guo)(guo)爐(lu)受熱(re)(re)(re)(re)面用(yong)(yong)(yong)(yong)(yong)的(de)(de)碳(tan)素(su)(su)鋼(gang)(gang)(gang)、合(he)金鋼(gang)(gang)(gang)和(he)不(bu)銹耐熱(re)(re)(re)(re)鋼(gang)(gang)(gang)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)。5高(gao)壓化肥設備用(yong)(yong)(yong)(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)是(shi)適用(yong)(yong)(yong)(yong)(yong)于(yu)工作溫度為-40~400℃、工作壓力為10~30Ma的(de)(de)化工設備和(he)管(guan)(guan)(guan)(guan)(guan)道(dao)的(de)(de)碳(tan)素(su)(su)結構(gou)鋼(gang)(gang)(gang)和(he)合(he)金鋼(gang)(gang)(gang)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)。6．石油裂化用(yong)(yong)(yong)(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)，主要用(yong)(yong)(yong)(yong)(yong)于(yu)石油冶(ye)煉(lian)廠的(de)(de)鍋(guo)(guo)爐(lu)、熱(re)(re)(re)(re)交換器(qi)及(ji)其輸送(song)流體(ti)管(guan)(guan)(guan)(guan)(guan)道(dao)。7.地質鉆探(tan)用(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)（YB235-70）是(shi)供地質部門進(jin)行巖(yan)心鉆探(tan)使用(yong)(yong)(yong)(yong)(yong)的(de)(de)鋼(gang)(gang)(gang)管(guan)(guan)(guan)(guan)(guan)等

無(wu)縫鋼管出廠前(qian)的基礎檢測(ce)有哪些(xie)？

熱(re)(re)軋(ya)無(wu)(wu)縫(feng)鋼管的(de)(de)交(jiao)貨(huo)(huo)狀態(tai)一(yi)般是在(zai)(zai)熱(re)(re)軋(ya)狀態(tai)經(jing)過熱(re)(re)處(chu)理(li)后進(jin)(jin)行(xing)(xing)交(jiao)貨(huo)(huo)的(de)(de)。因為，熱(re)(re)軋(ya)無(wu)(wu)縫(feng)鋼管在(zai)(zai)經(jing)過質(zhi)檢后要(yao)經(jing)過工作人(ren)員的(de)(de)嚴(yan)格的(de)(de)手工挑選，每一(yi)個步(bu)(bu)驟(zou)(zou)都(dou)力(li)臻(zhen)完美，做到(dao)精益求精。在(zai)(zai)質(zhi)檢后要(yao)進(jin)(jin)行(xing)(xing)表面涂油，然后緊接著是多(duo)次的(de)(de)冷拔實驗，熱(re)(re)軋(ya)處(chu)理(li)后要(yao)進(jin)(jin)行(xing)(xing)穿孔(kong)的(de)(de)實驗，如果穿孔(kong)擴徑過大就要(yao)進(jin)(jin)行(xing)(xing)矯(jiao)直矯(jiao)正。在(zai)(zai)矯(jiao)直后再由傳送裝置傳送到(dao)探(tan)傷機進(jin)(jin)行(xing)(xing)探(tan)傷實驗，這個步(bu)(bu)驟(zou)(zou)也同樣必不可少，貼上標(biao)簽、進(jin)(jin)行(xing)(xing)規格編排后放置到(dao)到(dao)倉庫當中。通過這一(yi)系列的(de)(de)步(bu)(bu)驟(zou)(zou)，為的(de)(de)就是更好(hao)的(de)(de)保(bao)證無(wu)(wu)縫(feng)鋼管出廠前的(de)(de)質(zhi)量(liang)。

所以，選擇(ze)購(gou)買(mai)這(zhe)種類型(xing)的管(guan)道(dao)(dao)材料是完全可以放(fang)心的，因為無(wu)縫鋼管(guan)在出場前都需要接受(shou)專業的檢測，這(zhe)樣不但保證了質量(liang)，同時，也讓客戶買(mai)的更加放(fang)心，不用擔心買(mai)到以次充好的管(guan)道(dao)(dao)材料。
