  1. 范圍：明確了標(biāo)準(zhǔn)適用的鋯及鋯合金焊管類型，包括材料、尺寸規(guī)格及其應(yīng)用領(lǐng)域。

  2. 規(guī)范性引用文件：列出了實(shí)施本標(biāo)準(zhǔn)時(shí)需要參考的其他國(guó)家標(biāo)準(zhǔn)或國(guó)際標(biāo)準(zhǔn)文獻(xiàn)。

  3. 術(shù)語(yǔ)和定義：對(duì)標(biāo)準(zhǔn)中涉及的專業(yè)術(shù)語(yǔ)進(jìn)行了解釋，確保讀者對(duì)關(guān)鍵概念有共同的理解。

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

  5. 技術(shù)要求：

    • 材料：規(guī)定了可用于制造焊管的鋯及鋯合金牌號(hào)及其化學(xué)成分要求。
    • 制造工藝：概述了焊管的制造過(guò)程應(yīng)滿足的技術(shù)條件，如焊接方法、熱處理等。
    • 尺寸、外形和允許偏差：詳細(xì)說(shuō)明了焊管的外徑、壁厚、長(zhǎng)度及其允許的尺寸偏差范圍。
    • 機(jī)械性能：規(guī)定了焊管需達(dá)到的最小抗拉強(qiáng)度、屈服強(qiáng)度、延伸率等指標(biāo)。
    • 物理性能和化學(xué)性能：包括密度、導(dǎo)熱性、耐腐蝕性等要求。
    • 表面質(zhì)量：對(duì)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(yàn)方法：詳細(xì)描述了驗(yàn)證焊管是否符合上述技術(shù)要求的各種檢測(cè)和試驗(yàn)手段，如拉伸試驗(yàn)、彎曲試驗(yàn)、無(wú)損檢測(cè)等。

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

  8. 包裝、標(biāo)志、運(yùn)輸和儲(chǔ)存：規(guī)定了焊管在出廠前的包裝要求、產(chǎn)品標(biāo)識(shí)信息、安全運(yùn)輸措施以及適宜的儲(chǔ)存條件，以防止損傷和腐蝕。

實(shí)施意義

此標(biāo)準(zhǔn)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(biāo)準(zhǔn)依據(jù)，有助于提升產(chǎn)品質(zhì)量，促進(jìn)產(chǎn)業(yè)標(biāo)準(zhǔn)化進(jìn)程，同時(shí)為國(guó)內(nèi)外貿(mào)易提供技術(shù)支撐，保障用戶權(quán)益。
