热轧无缝钢管重量

说明：无缝钢管具有中空截面，大量用作输送流体的管道，如输送石油、天然气、煤气、水及某些固体物料的管道等。钢管与圆钢等实心钢材相比，在抗弯抗扭强度相同时，重量较轻，是—种经济截面钢材，广泛用于制造结构件和机械零件，如石油钻杆、汽车传动轴、自行车架以及建筑施工中用的钢脚手架等用钢管制造环形零件，可提高材料利用率，简化制造工序，节约材料和加工工时，已广泛用钢管来制造。一般的无缝钢管的生产工艺可以分为冷拔与热轧两种，冷轧无缝钢管的生产流程—般要比热轧要复杂，管坯首先要进行三混连轧，挤压后要进行定径测试，如果表面没有响应裂纹后圆管要经过割机进行切割，切割成长度约—米的坯料。然后进入退火流程，退火要用酸性液体进行酸洗，酸洗时要注意表面是否有大量的起泡产生，如果有大量的起泡产生说明钢管的质量达不到相应的标准。外观上冷轧无缝钢管要短于热轧无缝钢管，冷轧无缝钢管的壁厚一般比热轧无缝钢管要小，但是表面看起来比厚壁无缝钢管更加明亮，表面没有太多的粗糙，口径也没有太多的毛刺。

标准：采用国标:《GB/T 17395-2008 无缝钢管尺寸、外形、重量及允许偏差》
