style="font-size:14px;"><strong>關鍵指標</strong></span><br /> <span style="font-size:14px;">材料選擇：材料是保障通風管道質量的基礎。常用的材料如鍍鋅板、不銹鋼板等需滿足耐腐蝕性、耐熱性、抗氧化性等要求。特殊環境下，還需選擇特殊材料進行加工。</span><br /> <span style="font-size:14px;">尺寸精度：管道的尺寸，包括直徑、長度、壁厚等，必須嚴格控制，以滿足通風系統的設計要求。</span><br /> <span style="font-size:14px;">連接質量：連接方式如螺紋連接、法蘭連接、焊接連接等，必須確保連接的牢固性和密封性，避免漏風、漏水等問題。</span><br /> <span style="font-size:14px;">表面處理：為提高管道的使用壽命和耐腐蝕性，常采用防腐涂層、耐磨涂層等表面處理。這些涂層的附著力和厚度是重要指標。</span><br /> <span style="font-size:14px;">安裝質量：管道的安裝牢固、穩定，水平度、垂直度、安裝位置等都需滿足要求。</span><br /> <br /> <span style="font-size:14px;"><strong>檢測方法</strong></span><br /> <span style="font-size:14px;">材料檢測：對原材料進行化學分析、機械性能測試等，以確保其滿足設計要求。</span><br /> <span style="font-size:14px;">尺寸檢測：使用卡尺、測量儀等工具對管道的尺寸進行準確測量，確保符合設計要求。</span><br /> <span style="font-size:14px;">連接檢測：通過目視檢查、拉力測試、氣壓測試等方法，檢查連接的牢固性和密封性。</span><br /> <span style="font-size:14px;">表面檢測：采用涂層厚度測量儀、顯微鏡等設備，檢查涂層的附著力和厚度。</span><br /> <span style="font-size:14px;">安裝檢測：通過水平尺、垂直尺等工具，檢查管道的安裝質量，確保其滿足設計要求。</span><br /></div> </td> </tr> </table> </p> </div> </div>
