  Q345D無縫管哪里有

  Q345D無縫鋼管主要特性:

  綜合力學性(xing)能(neng)好(hao),焊接性(xing),冷,熱加工性(xing)能(neng)和耐(nai)腐蝕(shi)性(xing)能(neng)均(jun)好(hao),具有(you)良好(hao)的低溫韌(ren)性(xing)

  Q345D無縫鋼管產品應用:

  船舶,鍋爐(lu),壓力容器,石油儲(chu)罐,橋梁,電站設備,起重運輸機械(xie)及其他(ta)較高載(zai)荷的焊接結構件

  Q345D無縫鋼管舊標準對照:

  18Nb含Nb鎮靜鋼,性能(neng)與(yu)14MnNb相近,主要用于起重(zhong)機,鼓風(feng)機,化(hua)工機械等

  09MnCuPTi耐大氣腐(fu)蝕(shi)用鋼,低溫沖(chong)擊韌性好,可焊性,冷熱(re)加工性能(neng)都(dou)好,主(zhu)要用于潮濕多雨地(di)區和(he)腐(fu)蝕(shi)氣氛環境的各種(zhong)機械

  12MnV工作(zuo)溫(wen)度為-70度低溫(wen)用鋼,主(zhu)要用于冷凍機械,低溫(wen)下工作(zuo)的結構件(jian)

  14MnNb性能與18Nb鋼相近(jin),主要用(yong)于(yu)工作溫度-20--450度的容器及其他結構件

  16Mn綜合力(li)學性(xing)(xing)(xing)能好,低溫性(xing)(xing)(xing)能,冷沖(chong)壓性(xing)(xing)(xing)能,焊接性(xing)(xing)(xing)能和(he)可(ke)切削性(xing)(xing)(xing)能都(dou)好,主(zhu)要用于礦山,運輸,化工等各種機械

  16MnRE性(xing)能(neng)與(yu)16Mn鋼(gang)相似,沖擊韌性(xing)和冷彎性(xing)能(neng)比16Mn好,用途同于16Mn鋼(gang)

  按照斷面形(xing)(xing)(xing)狀(zhuang),Q345D無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)分(fen)圓形(xing)(xing)(xing)和(he)異形(xing)(xing)(xing)兩種,異形(xing)(xing)(xing)管(guan)(guan)(guan)有方(fang)形(xing)(xing)(xing)、橢圓形(xing)(xing)(xing)、三(san)角(jiao)形(xing)(xing)(xing)、六角(jiao)形(xing)(xing)(xing)、瓜子形(xing)(xing)(xing)、星形(xing)(xing)(xing)、 帶(dai)翅(chi)管(guan)(guan)(guan)多種復雜形(xing)(xing)(xing)狀(zhuang)。******直(zhi)徑達650mm,***小(xiao)直(zhi)徑為 0.3mm。根據用(yong)途不同(tong), 有厚壁管(guan)(guan)(guan)和(he)薄壁管(guan)(guan)(guan)。無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)主要(yao)用(yong)做石油地(di)質鉆探管(guan)(guan)(guan)、石油化工用(yong)的裂化管(guan)(guan)(guan)、鍋(guo) 爐管(guan)(guan)(guan)、軸承管(guan)(guan)(guan)以及汽(qi)車、拖(tuo)拉(la)機、航空用(yong)高精度(du)結構(gou)鋼(gang)管(guan)(guan)(guan)。

  沿其橫截面的周邊上無接(jie)縫的鋼(gang)(gang)管(guan)(guan)。Q345D無縫鋼(gang)(gang)管(guan)(guan)Q345D無縫鋼(gang)(gang)管(guan)(guan)根(gen)據生產方(fang)法不同分為熱(re)軋(ya)管(guan)(guan)、冷軋(ya)管(guan)(guan)、冷拔(ba)管(guan)(guan)、擠(ji)壓管(guan)(guan)、頂(ding)管(guan)(guan)等,均有各自(zi)工藝規定(ding)。材質有普通和(he)(he)優質碳素結構鋼(gang)(gang)(Q215-A~Q275-A和(he)(he)10~50號鋼(gang)(gang))、低(di)合金鋼(gang)(gang)(09MnV、16Mn等)、合金鋼(gang)(gang)、不銹(xiu)耐酸(suan)鋼(gang)(gang)等。按用(yong)途分為一(yi)般用(yong)途的(用(yong)于輸水(shui)、氣管(guan)(guan)道和(he)(he)結構件、機械零件)和(he)(he)專用(yong)的(用(yong)于鍋爐(lu)、地質勘(kan)探、軸承、耐酸(suan)等)兩類。

  Q345D無(wu)縫(feng)鋼(gang)(gang)(gang)管(guan)(guan)用(yong)途(tu)很(hen)廣(guang)泛。一般用(yong)途(tu)的無(wu)縫(feng)鋼(gang)(gang)(gang)管(guan)(guan)由(you)普通的碳素結(jie)(jie)構(gou)(gou)(gou)鋼(gang)(gang)(gang)、低合金結(jie)(jie)構(gou)(gou)(gou)鋼(gang)(gang)(gang)或(huo)合金結(jie)(jie)構(gou)(gou)(gou)鋼(gang)(gang)(gang)軋制,產量***多,主(zhu)要(yao)用(yong)作輸送流(liu)體的管(guan)(guan)道或(huo)結(jie)(jie)構(gou)(gou)(gou)零件。.2、根(gen)據用(yong)途(tu)不(bu)同分(fen)三類(lei)供(gong)(gong)應:a、按(an)化學成分(fen)和(he)機械性(xing)能供(gong)(gong)應;b、按(an)機械性(xing)能供(gong)(gong)應;c、按(an)水(shui)壓試(shi)驗供(gong)(gong)應。按(an)a、b類(lei)供(gong)(gong)應的鋼(gang)(gang)(gang)管(guan)(guan),如用(yong)于承(cheng)受液體壓力(li),也要(yao)進(jin)行水(shui)壓試(shi)驗。3、專(zhuan)門用(yong)途(tu)的無(wu)縫(feng)管(guan)(guan)有鍋爐用(yong)無(wu)縫(feng)管(guan)(guan)、化工電力(li)用(yong),地質用(yong)無(wu)縫(feng)鋼(gang)(gang)(gang)管(guan)(guan)及石油用(yong)無(wu)縫(feng)管(guan)(guan)等多種。

  Q345D無(wu)縫(feng)鋼(gang)(gang)管(guan)具有(you)中空截(jie)面,大(da)量用作輸送(song)流體的(de)管(guan)道,如(ru)輸送(song)石油(you)、天然氣、煤氣、水及某(mou)些固(gu)體物(wu)料(liao)的(de)管(guan)道等。Q345D無(wu)縫(feng)鋼(gang)(gang)管(guan)與圓鋼(gang)(gang)等實心鋼(gang)(gang)材相(xiang)比,在抗(kang)彎抗(kang)扭強度相(xiang)同時,重量較輕,是一種經濟截(jie)面鋼(gang)(gang)材。

  廣泛用(yong)(yong)于制造結構件(jian)和(he)機械(xie)零(ling)件(jian),如石油鉆(zhan)桿、汽(qi)車(che)傳動軸、自行車(che)架以(yi)及建筑(zhu)施工(gong)(gong)中用(yong)(yong)的(de)鋼(gang)腳手架等用(yong)(yong)鋼(gang)管制造環形零(ling)件(jian),可提高材料利用(yong)(yong)率,簡化(hua)制造工(gong)(gong)序,節(jie)約材料和(he)加工(gong)(gong)工(gong)(gong)時,已廣泛用(yong)(yong)鋼(gang)管來制造。
