碳钢无缝钢管 碳钢无缝钢管是一种具有的长条钢材。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的同时,重量较轻,是一种经济截面钢材,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。

简介
播报编辑碳钢无缝钢管是一种具有的长条钢材。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的同时,重量较轻,是一种经济截面钢材,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,如滚动轴承套圈、千斤顶套等,当前已广泛用钢管来制造。钢管还是各种常规武器不可缺少的材料,枪管、 炮筒等都要钢管来制造。钢管按横截面积形状的不同可分为圆管和异型管。由于在周长相等的条件下,圆面 积最大,用圆形管可以输送更多的流体。此外,圆环截面在承受内部或外部径向压力时,受力较均匀 ,因此,绝大多数钢管是圆管。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,如滚动轴承套圈、千斤顶套等,当前已广泛用钢管来制造。分为10#无缝钢管、20#无缝钢管、45#无缝钢管等。
材质因素
播报编辑(1)结构的重要性 重型工业建筑结构、大跨度结构、高层或超高层的民用建筑结构或构筑物等重要结构,应考虑选用质量好的无缝钢管,对一般工业与民用建筑结构,可按工作性质分别选用普通质量的无缝钢管。(2)荷载情况 直接承受动力荷载的结构和强烈地震区的结构,应选用综合性能好的无缝钢管;一般承受静力荷载的结构则可选用价格较低的无缝钢管。(3)连接方法 焊接过程会产生焊接变形、焊接应力以及其他焊接缺陷,存在导致结构产生裂缝或脆性断裂的危险。因此,焊接结构对材质的要求应严格一些。(4)结构所处的温度和环境,无缝钢管处于低温时容易冷脆,因此在低温条件下工作的结构,尤其是焊接结构,应选用具有良好抗低温脆断性能的镇静钢。此外,露天结构的太原无缝钢管容易产生时效,有害介质作用的无缝钢管容易腐蚀、疲劳和断裂,也应加以区别地选择不同材质。(5)太无缝钢管厚度,薄无缝钢管辊轧次数多,轧制的压缩比大,厚度大的无缝钢管压缩比小,所以厚度大的精密钢管不但强度较小,而且塑性、冲击韧性和焊接性能也较差。因此,厚度大的焊接结构应采用材质较好的无缝钢管。
标准
播报编辑碳素钢无缝钢管有以下几种标准:GB8163《流体输送用无缝钢管》、GB6479《化肥设备用高压无缝钢管》、GB9948《石油裂化用无缝钢管》、GB3087《低中压锅炉用无缝钢管》、GB5310《高压锅炉用无缝钢管》。新手上路成长任务编辑入门编辑规则本人编辑天天电玩城有疑问内容质疑在线客服官方贴吧意见反馈投诉建议举报不良信息未通过词条申诉投诉侵权信息封禁查询与解封?2023?Baidu?使用百度前必读?|?百科协议?|?隐私政策?|?百度百科合作平台?|?京ICP证030173号?京公网安备11000002000001号window.PAGE_DATA=
