焊管的焊縫質(zhì)量不斷提高，其種類規(guī)范也日益增多，并在越來越多的范疇替代了無縫鋼管。要使按焊縫方式進(jìn)行區(qū)別的話，焊管能夠分為直縫焊管和螺旋焊管兩種，前者的出產(chǎn)工藝要相對簡略一些，并且本錢比較低；可是強(qiáng)度方面明顯螺旋焊管更勝一籌。<pstyle="margin:0px;padding:0px;color:#666666;text-transform:none;line-height:30px;text-indent:0px;letter-spacing:normal;font-family:arial,helvetica,sans-serif;font-size:12px;font-style:normal;font-weight:400;word-spacing:0px;white-space:normal;orphans:2;widows:2;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;">正是由于如此，較小口徑的焊管大都選用直縫焊，而大口徑焊管則大多選用螺旋焊，確保成型的焊管質(zhì)量能否符合規(guī)定的規(guī)范。</pstyle="margin:0px;padding:0px;color:#666666;text-transform:none;line-height:30px;text-indent:0px;letter-spacing:normal;font-family:arial,helvetica,sans-serif;font-size:12px;font-style:normal;font-weight:400;word-spacing:0px;white-space:normal;orphans:2;widows:2;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;"></pstyle="margin:0px;padding:0px;color:#666666;text-transform:none;line-height:30px;text-indent:0px;letter-spacing:normal;font-family:arial,helvetica,sans-serif;font-size:12px;font-style:normal;font-weight:400;word-spacing:0px;white-space:normal;orphans:2;widows:2;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;">
