  3. 術語和定義：對標準中涉及的專業(yè)術語進行了解釋，確保讀者對關鍵概念有共同的理解。

  4. 分類和標記：規(guī)定了鋯及鋯合金焊管的分類方法和產(chǎn)品標記規(guī)則，便于識別和追溯。

  5. 技術要求：

    • 材料：規(guī)定了可用于制造焊管的鋯及鋯合金牌號及其化學成分要求。
    • 制造工藝：概述了焊管的制造過程應滿足的技術條件，如焊接方法、熱處理等。
    • 尺寸、外形和允許偏差：詳細說明了焊管的外徑、壁厚、長度及其允許的尺寸偏差范圍。
    • 機械性能：規(guī)定了焊管需達到的最小抗拉強度、屈服強度、延伸率等指標。
    • 物理性能和化學性能：包括密度、導熱性、耐腐蝕性等要求。
    • 表面質(zhì)量：對焊管內(nèi)外表面的平整度、清潔度、缺陷等有具體要求。

  6. 試驗方法：詳細描述了驗證焊管是否符合上述技術要求的各種檢測和試驗手段，如拉伸試驗、彎曲試驗、無損檢測等。

  7. 檢驗規(guī)則：確立了焊管的檢驗分類、抽樣方案、合格判定準則等，確保產(chǎn)品質(zhì)量控制的一致性和有效性。

  8. 包裝、標志、運輸和儲存：規(guī)定了焊管在出廠前的包裝要求、產(chǎn)品標識信息、安全運輸措施以及適宜的儲存條件，以防止損傷和腐蝕。

實施意義

此標準為鋯及鋯合金焊管的生產(chǎn)、交易和使用提供了統(tǒng)一的標準依據(jù)，有助于提升產(chǎn)品質(zhì)量，促進產(chǎn)業(yè)標準化進程，同時為國內(nèi)外貿(mào)易提供技術支撐，保障用戶權益。
