我公司主要經營螺旋鋼管，雙麵埋弧焊螺旋管，大口徑螺旋管，大口徑厚壁螺旋鋼管，普通流體輸送用螺旋管材質有，Q235B、Q345（16Mn）等材質螺旋焊管。螺旋焊管統稱的種類：luoxuanhanguandeqiangduyibanbizhifenghanguangao，nengyongjiaozhaidepiliaoshengchanguanjingjiaodadehanguan，haikeyiyongtongyangkuandudepiliaoshengchanguanjingbutongdehanguan。danshiyuxiangtongchangdudezhifengguanxiangbi，hanfengchangduzengjia30~100%，而且生產速度較低。因此，較小口徑的焊管大都采用直縫焊，大口徑焊管則大多采用螺旋焊管。1.承壓流體輸送，用螺旋縫埋弧焊鋼管SY5036-83，主要用於輸送石油、天然氣的管線；承壓流體輸送用螺旋縫高頻焊鋼管SY5038-83，用高頻搭接焊法焊接的，用於承壓流體輸送的螺旋縫高頻焊鋼管。鋼管承壓能力強，塑性好，便於焊接和加工成型；一般低壓流體輸送用螺旋縫埋弧焊鋼管SY5037-83，采用雙麵自動埋弧焊或單麵焊法製成的用於水、煤氣、空氣和蒸汽等一般低壓流體輸送用埋弧焊鋼管。
