非磁性钢管和普通无缝钢管哪里有明显区别,最大的区别就是非磁性,并不是磁铁不吸,原理不同,用处也就不一样,非磁性的表现就是高压电缆通过电压时吸附的铁沫过去电流就会脱落,而普通钢管恰恰相反,久而久之产生大量铁沫就会烧掉电缆。
非磁性钢管本体为铁管做镀锌层而成,所以镀锌钢管是有磁性的。 不锈钢也并非完全没有磁性,只是磁性非常低。
焊接带磁性钢管时,经常会看到电弧引燃的困难、电弧燃烧稳定性差、电弧偏离电极轴线、液体金属和熔渣从焊接熔池中的溅出,严重时无法建立焊接熔池,使焊接不能进行。为了稳定焊接过程,改普焊接接头质量,被磁化了的钢管在焊接前要进行消磁。应该指出,被焊接的钢管要达到完全消磁是困难的,当剩磁不足于影响焊接质量时,便允许进行焊接。
