什么是 ASTM A269 焊接不锈钢管?

ASTM A269 一般用途无缝和焊接奥氏体不锈钢管的标准规范。

焊接不锈钢管精度高,壁厚均匀,管材内部外观亮度高(钢管表面亮度由钢板表面等级决定),可任意定尺寸。1930年代以来,随着优质带钢连轧生产的快速发展和焊接检测技术的进步,焊缝质量不断提高,焊接钢管的品种和规格不断增加,在越来越多的领域(特别是换热设备用管材、装饰管、中低压流体管等)代替无缝钢管。

因此,焊接不锈钢管在高精度、中低压流体应用中体现了其经济性和美观性。


焊接不锈钢管的分类:

按焊缝形式分为直缝焊管和螺旋焊管。按用途分为普通焊管、换热器管、冷凝器管、镀锌焊管、吹氧焊管、电线套管、公制焊管、托辊管、深井泵管、汽车管、变压器管、电焊薄壁管、电焊异形管、螺旋焊管。
