螺旋聲測管出廠前怎樣質檢

螺旋聲測管出廠前怎樣質檢

日期:2020-05-18 14:59:20

通常螺旋聲測管剛生產制造出去都是歷經品質的檢驗。那麼,檢驗的方式都有哪些?接下去就讓小編來給您詳細介紹一下。

  一、硝酸點試驗:

主要特點之一是其對稀硝酸和濃硝酸的固有耐腐蝕性。

  二、磁性試驗:

  螺旋聲測管帶磁實驗是差別淬火方式的有效的方法。高壓冷加工后,它有輕微的磁性。然而,純低合金鋼和鉻鋼是強磁鋼。

  三、硫酸試驗:

  鹽酸實驗水溶液的容積濃度值為12%,加溫到63℃,當厚壁無縫管滲入這類熱水溶液中時,被快速浸蝕并造成很多汽泡,試件在十多分鐘迅速變為灰黑色。

  四、硫酸銅點試驗:

  硫酸銅點實驗是區別碳素結構鋼和全部種類的最簡變這種更快方式。
