无缝矩形管 环保镀锌矩形管 规格齐全可定做 太阳能发电支架专用

• 产品信息
• 执行标准： 国标

• 定义：矩形管是一种中空的长条钢材，又称扁管、扁方管或方扁管（顾名思义）。在抗弯、抗扭强度相同时，重量较轻，所以广泛用于制造机械零件和工程结构。

 矩形管的分类：钢管分无缝钢管和焊接钢管（有缝管）热轧无缝方管、冷拔无缝方管、挤压无缝方管、焊接方管。 　其中焊接方管又分为： 　(a)按工艺分——电弧焊方管、电阻焊方管(高频、低频)、气焊方管、炉焊方管 　(b)按焊缝分——直缝焊方管、螺旋焊方管。

 矩形管是一种空心方形的截面轻型薄壁钢管，也称为钢制冷弯型材。它是以Q235热轧或冷轧带钢或卷板为母材经冷弯曲加工成型后再经高频焊接制成的方形截面形状尺寸的型钢。热轧特厚壁方管除壁厚增厚外情况,其角部尺寸和边部平直度均达到甚至超过电阻焊冷成型方管的水平.

 用途：建筑，机械制造，钢铁建设项目， 造船，太阳能发电支架，钢结构工程，电力工程，电厂，农业和化学机械，玻璃幕墙，汽车底盘，机场等。

 安装过程中，定管、动管轴心线要在一条直线上，否则容易将胶圈顶出，影响安装的质量和速度。Q345无缝矩管安装要平，Q345无缝矩管之间应成直线，遇有倾斜角时，要小心。将连接Q345无缝矩管的接口对准承口，若插入阻力过大，切勿强行插入，以防橡胶圈扭曲。 橡胶圈润滑油宜用植物油;寒冷的冬季，橡胶圈可用热水预热，以减少硬度，迅速安装。
