埋弧焊鋼管

采用JCOE鋼管成型,一條焊縫,埋弧焊接工藝,規格范圍從325mm--1420mm。當直縫埋弧焊管直徑大于914.4時標準規定允許鋼管有兩條直焊縫。直縫埋弧焊管產品執行GB/T3091-2008的低壓流體鋼管標準、GB/T9711.1(2)-1997石油天燃氣管道執行標準、ASTM A252 焊接結構鋼管美國執行標準。直縫埋弧焊管的生產工藝靈活可生產范圍內的任何規格與壁厚,生產效率較高頻直縫焊鋼管、螺旋焊鋼管要低。直縫埋弧焊管最大優勢就在于可以生產高頻鋼管、螺旋鋼管、甚至無縫鋼管都不能生產的規格型號。直縫埋弧焊管生產成本比高頻鋼管、螺旋鋼管要高,但比起無縫鋼管價格優惠空間很大。直縫埋弧焊管可以生產高頻鋼管以及螺旋鋼管不能生產的材質,比如高頻鋼管通常是生產國內常用規格,并批量生產庫存,通常材質為Q235B、Q345B、L245 L245N,L360 一直到X70.直縫埋弧焊管在國內的重型鋼結構工程和流體管道工程,基礎打樁工程中得到廣范應用。
