鄂爾多斯無縫鋼管價格

　　鄂爾多斯無縫鋼管的無縫化主要是通過張力減徑來完成的，張力減徑過程是空心母材不帶芯棒的連續軋制過程。在保證母管焊接質量的前提下，鄂爾多斯無縫鋼管張(zhang)力減(jian)(jian)徑工藝是(shi)將焊管整體加(jia)熱(re)(re)(re)到950攝(she)氏度以上，再經張(zhang)力減(jian)(jian)徑機(ji)(ji)(張(zhang)力減(jian)(jian)徑機(ji)(ji)共有24道次(ci))軋制成各(ge)種外徑與壁厚(hou)的(de)成品管，采用此工藝所生產的(de)熱(re)(re)(re)軋鋼管與普(pu)通的(de)高(gao)頻焊管有本質(zhi)的(de)區別通過(guo)加(jia)熱(re)(re)(re)爐加(jia)熱(re)(re)(re)后(hou)其(qi)焊縫(feng)與母體的(de)金相組織和機(ji)(ji)械性(xing)能可以達(da)到完全(quan)一致此外 ，通過(guo)多道次(ci)的(de)張(zhang)力減(jian)(jian)徑機(ji)(ji)軋制和自(zi)動控制使得鄂(e)(e)爾多斯(si)無(wu)縫(feng)鋼管的(de)尺寸(cun)精(jing)度(尤其(qi)是(shi)管體圓度和壁厚(hou)精(jing)度)優于(yu)同類鄂(e)(e)爾多斯(si)無(wu)縫(feng)鋼管。
