3087無縫鋼管的標準是什么

　　什么是3087無縫鋼管?3087無縫鋼管是用鋼(gang)錠(ding)或實心管(guan)(guan)坯(pi)經穿孔制(zhi)成毛管(guan)(guan)，然后經熱軋(ya)、冷(leng)軋(ya)或冷(leng)撥制(zhi)成。3087無縫(feng)鋼(gang)管(guan)(guan)在我國鋼(gang)管(guan)(guan)業中(zhong)具有重要，3087無縫(feng)鋼(gang)管(guan)(guan)的地位。

　　3087無縫管的(de)原(yuan)料是圓(yuan)管(guan)(guan)(guan)坯，圓(yuan)管(guan)(guan)(guan)胚要(yao)(yao)經過(guo)(guo)切(qie)割機(ji)的(de)切(qie)割加工(gong)成(cheng)長度(du)約為1米的(de)坯料，并經傳(chuan)送(song)帶送(song)到熔(rong)爐內加熱。鋼(gang)(gang)坯被(bei)送(song)入熔(rong)爐內加熱，溫度(du)大約為1200攝(she)氏度(du)。燃(ran)料為氫氣(qi)或(huo)乙炔。爐內溫度(du)控制(zhi)是關鍵性(xing)的(de)問題.圓(yuan)管(guan)(guan)(guan)坯出爐后(hou)(hou)要(yao)(yao)經過(guo)(guo)壓(ya)，力穿(chuan)(chuan)孔(kong)(kong)機(ji)進(jin)行穿(chuan)(chuan)空。- -般較常見的(de)穿(chuan)(chuan)孔(kong)(kong)機(ji)是錐形輥穿(chuan)(chuan)孔(kong)(kong)機(ji)，這種穿(chuan)(chuan)孔(kong)(kong)機(ji)生產效率高(gao)，產品質量好，穿(chuan)(chuan)孔(kong)(kong)擴(kuo)徑(jing)(jing)量大，可穿(chuan)(chuan)多種鋼(gang)(gang)種。穿(chuan)(chuan)孔(kong)(kong)后(hou)(hou)，圓(yuan)管(guan)(guan)(guan)坯就先后(hou)(hou)被(bei)三輥斜軋(ya)、連軋(ya)或(huo)擠壓(ya)。擠壓(ya)后(hou)(hou)要(yao)(yao)脫管(guan)(guan)(guan)定徑(jing)(jing)。定徑(jing)(jing)機(ji)通過(guo)(guo)錐形鉆(zhan)頭(tou)高(gao)速旋轉(zhuan)入鋼(gang)(gang)胚打孔(kong)(kong)，形成(cheng)無縫(feng)(feng)管(guan)(guan)(guan)。無縫(feng)(feng)管(guan)(guan)(guan)內徑(jing)(jing)由定機(ji)鉆(zhan)頭(tou)的(de)外徑(jing)(jing)長度(du)來確定。無縫(feng)(feng)管(guan)(guan)(guan)經定徑(jing)(jing)后(hou)(hou)，進(jin)入冷卻塔中，通過(guo)(guo)噴(pen)水冷卻，無縫(feng)(feng)管(guan)(guan)(guan)經冷卻后(hou)(hou)，就要(yao)(yao)被(bei)矯(jiao)直。無縫(feng)(feng)管(guan)(guan)(guan)經矯(jiao)直后(hou)(hou)由傳(chuan)送(song)帶送(song)至金(jin)屬探傷機(ji)(或(huo)水壓(ya)實驗)進(jin)行內部探傷。若鋼(gang)(gang)管(guan)(guan)(guan)內部有裂紋，氣(qi)泡等(deng)問題，將被(bei)探測出。鋼(gang)(gang)管(guan)(guan)(guan)質檢后(hou)(hou)還要(yao)(yao)通過(guo)(guo)嚴格(ge)的(de)手工(gong)挑選。無縫(feng)(feng)管(guan)(guan)(guan)質檢后(hou)(hou)，用油漆噴(pen)上編號(hao)、規(gui)格(ge)、生產批號(hao)等(deng)。并由吊車吊入倉(cang)庫(ku)中。規(gui)格(ge): 3087無縫(feng)(feng)管(guan)(guan)(guan)的(de)規(gui)格(ge)用外徑(jing)(jing)*壁厚亳米數表(biao)示(shi)。

　　3087無(wu)(wu)縫(feng)(feng)(feng)管(guan)(guan)的(de)分(fen)類(lei):無(wu)(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)分(fen)熱軋(ya)和冷軋(ya)(撥)無(wu)(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)兩(liang)類(lei)。熱軋(ya)無(wu)(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)分(fen)- - 般鋼(gang)管(guan)(guan)，低、中壓鍋爐鋼(gang)管(guan)(guan)，高(gao)壓鍋爐鋼(gang)管(guan)(guan)、合(he)金鋼(gang)管(guan)(guan)、不銹(xiu)鋼(gang)管(guan)(guan)、石(shi)油(you)裂化管(guan)(guan)、地質鋼(gang)管(guan)(guan)和其(qi)它鋼(gang)管(guan)(guan)等(deng)。
