<p>焊接钢管：&nbsp; 焊接钢管<br /> 也叫焊管，它是由钢带切割成窄钢条，然后用模具冷加工裹成管状。然后专用焊机接着将一条管缝焊接。外焊缝打磨光亮。一般的焊管的内毛刺不打的。只有精密焊管才打内毛刺。 　　防腐蚀分：焊接钢管是指用钢带或钢板弯曲变形为圆形、方形等形状后再焊接成的、表面有接缝的钢管。按焊接方法不同可分为电弧焊管、高频或低频电阻焊管、气焊管、炉焊管、邦迪管等。按焊缝形状可分为直缝焊管和螺旋焊管。电焊钢管用于石油钻采和机械、制造业等。炉焊管可用作水煤气管等，大口径直缝焊管用于高压油气输送等；螺旋焊管用于油气输送、管桩、桥墩等。焊接钢管比无缝钢管成本低、生产效率高。</p> <p>镀锌管 Ф48*3.25 Q195-215 邯郸友发 5030 5030 -&nbsp; <br /> 镀锌管 Ф114*3.75 Q195-235 邯郸友发 4840 4840 -&nbsp; <br /> 镀锌管 Ф114*3.75 Q195-235 天津友发 5120 5120 - 货少 <br /> 镀锌管 Ф168*4.0 Q195-235 天津友发 5320 5320 - 货少 <br /> 镀锌管 Ф219*5.0 Q195-235 天津友发 5420 5420 - 货少 </p> <p>材质有：12Cr1MoV、15CrMo、20CrMo、30CrMo、35CrMo、42CrMo、20Cr、40Cr、20Mn、50Mn、1025、45#、30#、10#、50#、20#、Q345A、Q390A、Q420A、Q460C、A572Gr50、SM490B、St52-3、S275JR、S355JR、WH60A、50Mn2V、20Mn2、40Mn2、20MnSi、10CrMoAL、20CrMnMo、12CrMoVNi、30CrMnSiA、Cr5Mo、Cr9Mo、A335P11、A335P22、10CrMo910</p> <p>不锈钢管材质有:321 304 304L 316 316L 310S\1Cr18Ni9Ti 0Cr18Ni10Ti 0Cr18Ni9 00Cr18Ni10 0Cr17Ni12Mo2 00Cr17Ni14Mo2 0Cr25Ni20</p> <p>我公司在聊城地区合金钢板、合金圆钢的特约经销商。主营：12Cr1MoV合金板和15CrMo合金板，同时还常年销售舞钢、武钢、太钢、鞍钢、济钢、沙钢 马钢等过内几大钢厂生产的合金板，合金钢板，圆钢，<a style="word-spacing:0px;font:medium Simsun;text-transform:none;text-indent:0px;white-space:normal;letter-spacing:normal;background-color:#ffffff;orphans:2;widows:2;webkit-text-size-adjust:auto;webkit-text-stroke-width:0px;" href="http://www.tjwffg.com/">厚壁方管</a><span style="display:inline!
