單就種類上看，無縫管的種類是比較多樣的，市面上，需求量較高的有熱擴無縫鋼管和大口徑無縫鋼管這兩種，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。在中國，比較著名的無縫管生產地，主要集中在崇鋼、包鋼，無錫、山東、冶鋼、鞍鋼等地，可以說，需求量還是很大的。而在材質上，也會根據用途的不同而略有差異。

　　如果將無(wu)(wu)縫(feng)管(guan)(guan)(guan)(guan)進行細致的(de)劃分(fen)，可以被分(fen)為冷拔無(wu)(wu)縫(feng)鋼管(guan)(guan)(guan)(guan)，熱軋無(wu)(wu)縫(feng)鋼管(guan)(guan)(guan)(guan)、大口徑厚壁無(wu)(wu)縫(feng)鋼管(guan)(guan)(guan)(guan)，中低壓鍋(guo)爐用(yong)無(wu)(wu)縫(feng)鋼管(guan)(guan)(guan)(guan)、輸(shu)送流體用(yong)無(wu)(wu)縫(feng)鋼管(guan)(guan)(guan)(guan)、結構(gou)用(yong)無(wu)(wu)縫(feng)鋼管(guan)(guan)(guan)(guan)、建筑用(yong)無(wu)(wu)縫(feng)鋼管(guan)(guan)(guan)(guan)等幾大系列，再(zai)根(gen)據具(ju)體的(de)用(yong)途來進行選擇，不(bu)但簡單方便，同時這(zhe)種(zhong)有針對性(xing)的(de)管(guan)(guan)(guan)(guan)道材料(liao)，也能從某(mou)種(zhong)程度上(shang)提升工作效(xiao)率。

　　無(wu)縫管(guan)因其用途不同的各種(zhong)分類

　　無(wu)(wu)(wu)縫(feng)(feng)管(guan)(guan)(guan)在各個領域有(you)著不同的(de)(de)(de)作(zuo)(zuo)用(yong)(yong)，具體幾大分類如下1.結構(gou)用(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)：主要(yao)用(yong)(yong)于(yu)一(yi)般結構(gou)和機械結構(gou)。2.輸(shu)送流體用(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)：主要(yao)用(yong)(yong)于(yu)工(gong)(gong)程及大型設備(bei)(bei)上(shang)輸(shu)送流體管(guan)(guan)(guan)道3低(di)中(zhong)(zhong)壓(ya)鍋(guo)(guo)(guo)爐用(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)是用(yong)(yong)于(yu)制造各種結構(gou)低(di)中(zhong)(zhong)壓(ya)鍋(guo)(guo)(guo)爐過熱(re)(re)蒸汽管(guan)(guan)(guan)、沸(fei)水管(guan)(guan)(guan)及機車鍋(guo)(guo)(guo)爐用(yong)(yong)過熱(re)(re)蒸汽管(guan)(guan)(guan)、大煙管(guan)(guan)(guan)、小煙管(guan)(guan)(guan)和拱磚(zhuan)管(guan)(guan)(guan)用(yong)(yong)的(de)(de)(de)碳素(su)(su)結構(gou)鋼(gang)(gang)(gang)熱(re)(re)軋和冷(leng)拔（軋）無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)。4.高壓(ya)鍋(guo)(guo)(guo)爐用(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)是用(yong)(yong)于(yu)制造高壓(ya)及其以上(shang)壓(ya)力的(de)(de)(de)水管(guan)(guan)(guan)鍋(guo)(guo)(guo)爐受熱(re)(re)面用(yong)(yong)的(de)(de)(de)碳素(su)(su)鋼(gang)(gang)(gang)、合金鋼(gang)(gang)(gang)和不銹耐熱(re)(re)鋼(gang)(gang)(gang)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)。5高壓(ya)化(hua)(hua)肥設備(bei)(bei)用(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)是適用(yong)(yong)于(yu)工(gong)(gong)作(zuo)(zuo)溫(wen)度為(wei)-40~400℃、工(gong)(gong)作(zuo)(zuo)壓(ya)力為(wei)10~30Ma的(de)(de)(de)化(hua)(hua)工(gong)(gong)設備(bei)(bei)和管(guan)(guan)(guan)道的(de)(de)(de)碳素(su)(su)結構(gou)鋼(gang)(gang)(gang)和合金鋼(gang)(gang)(gang)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)。6．石(shi)(shi)油裂化(hua)(hua)用(yong)(yong)無(wu)(wu)(wu)縫(feng)(feng)鋼(gang)(gang)(gang)管(guan)(guan)(guan)，主要(yao)用(yong)(yong)于(yu)石(shi)(shi)油冶煉廠的(de)(de)(de)鍋(guo)(guo)(guo)爐、熱(re)(re)交換器及其輸(shu)送流體管(guan)(guan)(guan)道。7.地(di)(di)質(zhi)鉆(zhan)探(tan)用(yong)(yong)鋼(gang)(gang)(gang)管(guan)(guan)(guan)（YB235-70）是供地(di)(di)質(zhi)部門進行巖心鉆(zhan)探(tan)使(shi)用(yong)(yong)的(de)(de)(de)鋼(gang)(gang)(gang)管(guan)(guan)(guan)等(deng)

　　無(wu)縫鋼管出廠前的基礎檢測有(you)哪些(xie)？

　　熱(re)(re)軋(ya)無(wu)(wu)縫(feng)鋼(gang)(gang)管(guan)的(de)(de)交貨(huo)狀(zhuang)態(tai)一(yi)般是在(zai)(zai)熱(re)(re)軋(ya)狀(zhuang)態(tai)經(jing)(jing)過(guo)熱(re)(re)處理(li)后(hou)進(jin)(jin)(jin)行(xing)交貨(huo)的(de)(de)。因為(wei)，熱(re)(re)軋(ya)無(wu)(wu)縫(feng)鋼(gang)(gang)管(guan)在(zai)(zai)經(jing)(jing)過(guo)質(zhi)檢(jian)后(hou)要(yao)(yao)經(jing)(jing)過(guo)工(gong)作人(ren)員的(de)(de)嚴(yan)格(ge)的(de)(de)手工(gong)挑(tiao)選，，做到精益求精。在(zai)(zai)質(zhi)檢(jian)后(hou)要(yao)(yao)進(jin)(jin)(jin)行(xing)表(biao)面涂油，然后(hou)緊接(jie)著是多次的(de)(de)冷拔實(shi)(shi)驗，熱(re)(re)軋(ya)處理(li)后(hou)要(yao)(yao)進(jin)(jin)(jin)行(xing)穿(chuan)孔的(de)(de)實(shi)(shi)驗，如果穿(chuan)孔擴徑過(guo)大就(jiu)要(yao)(yao)進(jin)(jin)(jin)行(xing)矯直矯正。在(zai)(zai)矯直后(hou)再由傳送裝置傳送到探(tan)傷機進(jin)(jin)(jin)行(xing)探(tan)傷實(shi)(shi)驗，這(zhe)(zhe)個步驟也同樣不可(ke)少，貼上標簽、進(jin)(jin)(jin)行(xing)規格(ge)編排后(hou)放(fang)置到到倉(cang)庫(ku)當中。通過(guo)這(zhe)(zhe)一(yi)系(xi)列的(de)(de)步驟，為(wei)的(de)(de)就(jiu)是更好的(de)(de)無(wu)(wu)縫(feng)鋼(gang)(gang)管(guan)出廠(chang)前的(de)(de)質(zhi)量。

　　所以，選擇購買這(zhe)種(zhong)類(lei)型的(de)管道材(cai)(cai)料是完全可以放心(xin)的(de)，因為無(wu)縫(feng)鋼管在出場前都需要(yao)接受檢測，同時，也讓客戶(hu)買的(de)放心(xin)，不用擔心(xin)買到以次充好的(de)管道材(cai)(cai)料。
