  Q355B鋼板卷管 直(zhi)徑500-1800mm

  鋼板卷管因其原料和用途不合而分為以下多種規格:1、GB/T3091-2001(低壓流體保送用鍍鋅鋼板卷管)。首要用于保送水、煤氣、空氣、油和取暖熱水或蒸汽等一般較低壓力流體和其它用途管。其代表原料為:Q235A級鋼。2、GB/T14291-2006(礦用流體保送鋼板卷管)。首要用(yong)(yong)于礦山壓(ya)風、排水、軸放瓦斯(si)用(yong)(yong)直縫(feng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷管(guan)(guan)(guan)。,卷管(guan)(guan)(guan)加工選用(yong)(yong)的坯(pi)料(liao)是(shi)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)或(huo)帶(dai)鋼(gang)(gang)(gang)(gang),卷板(ban)(ban)(ban)加工因(yin)其(qi)(qi)焊(han)(han)接技術不(bu)合而(er)分(fen)為(wei)爐(lu)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷管(guan)(guan)(guan)、電(dian)焊(han)(han)(電(dian)阻(zu)焊(han)(han))管(guan)(guan)(guan)和主動電(dian)弧鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷管(guan)(guan)(guan)。因(yin)其(qi)(qi)焊(han)(han)接辦法(fa)的不(bu)合分(fen)為(wei)直縫(feng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷管(guan)(guan)(guan)和螺旋鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷管(guan)(guan)(guan)兩(liang)種。因(yin)其(qi)(qi)端部外形(xing)又分(fen)為(wei)圓(yuan)形(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷管(guan)(guan)(guan)和異型(方、扁等(deng))鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷管(guan)(guan)(guan)。,卷管(guan)(guan)(guan)是(shi)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)通(tong)過滾筒機把鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)成(cheng)形(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)坯(pi),用(yong)(yong)卷板(ban)(ban)(ban)機將鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)卷成(cheng)圓(yuan)弧并將鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)結合處焊(han)(han)接,形(xing)成(cheng)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)。形(xing)象一(yi)點地比喻,就好像用(yong)(yong)一(yi)張(zhang)紙卷成(cheng)一(yi)個(ge)紙筒。然后通(tong)過埋弧焊(han)(han)或(huo)者電(dian)焊(han)(han)等(deng)焊(han)(han)接成(cheng)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan),然后再到其(qi)(qi)他的整(zheng)(zheng)形(xing)設(she)備(bei)上定(ding)徑整(zheng)(zheng)形(xing),這種管(guan)(guan)(guan)子(zi)是(shi)單根生(sheng)產的效率低,管(guan)(guan)(guan)子(zi)質(zhi)量(liang)不(bu)穩定(ding),尺寸(cun)精(jing)度低,但是(shi)設(she)備(bei)簡單投資(zi)少。而(er)直縫(feng)焊(han)(han)管(guan)(guan)(guan)設(she)備(bei)效率高,管(guan)(guan)(guan)子(zi)質(zhi)量(liang)高,精(jing)度高,統一(yi)性(xing)好。

  鋼板卷(juan)管產品完全(quan)符合GB/T8162-2008、GB/T8163-2008、GB3087-2008、GB/T5037-2008GB/T3091/3092-2008\API5L/5CT、ASTMA106/A53、BS1387等標(biao)準。

  鋼板卷(juan)管主(zhu)要材質:10#、20#、45#、Q235B、Q345B、A106GR.B/A53B.20#.Q235B.Q345B.X42-X60.產品廣泛應用于石油,天然氣,煤氣,供熱,供水,以及電力化(hua)工(gong),水利,機械制作等(deng)方面。
