45#無縫鋼管的現貨資源目前規格齊全,無縫鋼管用途很廣泛,一般用途的無縫鋼管由普通的碳素結構鋼、低合金結構鋼或合金結構鋼軋制,產量多,主要用作輸送流體的管道或結構零件。根據用途(tu)不同(tong)分三類供應:
A、按化學成分和機械性能(neng)供應;
B、按機械)性能供應;
C、按水壓試驗供應。GB9948無縫鋼管主要用來生產氣動或液壓元件的產品,如氣缸或油缸,都是用無縫管。45#無縫鋼管的化學成(cheng)分有(you)(you)碳C、硅Si、錳Mn、硫S、磷(lin)P、鉻Cr。GB5310無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)按(an)照用(yong)(yong)途(tu)分為結(jie)構(gou)用(yong)(yong)無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan);輸送用(yong)(yong)無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan);鍋爐(lu)用(yong)(yong)無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan);鍋爐(lu)用(yong)(yong)高壓無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)、無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)按(an)照斷面(mian)形(xing)(xing)(xing)狀(zhuang),無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)分圓(yuan)形(xing)(xing)(xing)和異形(xing)(xing)(xing)兩種,異形(xing)(xing)(xing)管(guan)(guan)(guan)有(you)(you)方形(xing)(xing)(xing)、橢圓(yuan)形(xing)(xing)(xing)、三(san)角(jiao)(jiao)形(xing)(xing)(xing)、六角(jiao)(jiao)形(xing)(xing)(xing)、瓜子形(xing)(xing)(xing)、星形(xing)(xing)(xing)、帶翅(chi)管(guan)(guan)(guan)多種復雜形(xing)(xing)(xing)狀(zhuang)。按(an)b類供應的(de)鋼管,如(ru)用(yong)于承受液體(ti)壓(ya)力(li),也要進行水壓(ya)(特指:壓(ya)強)試驗(yan)。3、專(zhuan)門用(yong)途(tu)的(de)無縫(feng)管有(you)鍋爐用(yong)無縫(feng)管、化工(gong)電力(li)用(yong),地(di)質(zhi)用(yong)無縫(feng)鋼管及石油(you)(you)用(yong)無縫(feng)管等多種。無縫(feng)鋼管具有(you)中空截面,大量(liang)用(yong)作輸送(song)流體(ti)的(de)管道,如(ru)輸送(song)石油(you)(you)、天(tian)然氣、煤氣、水及某些固體(ti)物(wu)料的(de)管道等。鋼管與圓(yuan)鋼等實(shi)心鋼材相比,在抗彎抗扭強度相同(tong)時,重量(liang)較輕,是一種經濟截面鋼材。
