<p>无缝钢管 　　因其制造工艺不同，又分为热轧（挤压）无缝钢管和冷拔（轧）无缝钢管两种。冷拔（轧）管又分为圆形管和异形管两种。 　　a． 工艺流程概述 　　热轧（挤压无缝钢管）：圆管坯→加热→穿孔→三辊斜轧、连轧或挤压→脱管→定径（或减径）→冷却→坯管→矫直→水压试验（或探伤）→标记→入库。 　　冷拔（轧）无缝钢管：圆圆管坯→加热→穿孔→打头→退火→酸洗→涂油（镀铜）→多道次冷拔（冷轧）→坯管→热处理→矫直→水压试验（探伤）→标记→入库。 　　b．无缝钢管，因其用途不同而分为如下若干品种： 　　GB/T8162-2008（结构用无缝钢管）。主要用于一般结构和机械结构。其代表材质（牌号）：碳素钢20、45号钢；合金钢Q345、20Cr、40Cr、20CrMo、30-35CrMo、42CrMo等。</p> <p>城市 品名 规格 材质 钢厂/产地 价格&nbsp; <br /> 成都 焊管 Ф27*2.5 Q195-215 华岐 4710 <br /> 成都 焊管 Ф33*3.0 Q195-215 华岐 4590 <br /> 成都 焊管 Ф48*3.25 Q195-215 华岐 4460</p> <p>专业生产：304、304L、316、316L、310、310S、321不锈钢板材、不锈钢管材、<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.16mnhbg.com/">20#厚壁钢管</a><span style="display:inline!
