14px;">風管加工時，風管不得采用S形切割、C形直角切割和豎縫角切割的連接方式，空氣潔凈度等級為1 ~ 5級的風管不得采用咬口。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">空調系統風管法蘭鉚釘間距應小于100mm，空氣潔凈度等級為1 ~ 5級的風管法蘭鉚釘間距應小于65 mm。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">風管內不得設置鋼筋骨架或鋼筋。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">在加工風管前，應使用清洗液去除板材表面的油污和灰塵。清洗液應是對板面無損傷、干燥后不產生粉塵、對人體無害的中性洗滌劑。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">風管分段制作，風管分段制作中，我們要密切注意，看看有沒有漏洞。應以機械密封為主，輔以密封膠處理。每一段<a href='http://www.142779.com/news/473.html' target='_blank' class='key_tag'><font><strong>管道加工</strong></font></a>成型后，都要進行質量檢查。從現場施工來看，角鋼法蘭的強度和密封性能遠高于普通板式法蘭。在變風量系統中，建議優先采用角鋼法蘭。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">風管彎頭制造時，應按規范要求在風管彎頭位置設置回流片，尤其是尺寸較大的彎頭，會影響氣流，造成局部噪聲。設置導葉時，應注意導葉的合理位置和數量。在變風量系統中，風量根據末端需求而變化。</span></p><p style="text-align: center; text-indent: 2em;"><img
