class='key_tag'><font><strong>通風管道</strong></font></a>的制造商需要使用不銹鋼管道作為火災區域的排煙管道，以減少地下室上層的空間占用和風管的消耗。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">排煙系統的系統分區和防煙分區應結合建筑防火分區考慮。不銹鋼風管既要有利于地下室的通風系統，又要起到排煙系統的作用，避免排煙風管穿越防火分區的現象。因此，當使用一組風管時，系統應滿足火災時通風和排煙的要求。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">通常，在辦公樓和一些公共建筑的屋頂上可以看到通風管道。通風管道的安裝根據具體的建筑結構要求進行布置。通風管表面光滑，無褶皺、粗糙和斑點，質量好的通風管的彈性鋼絲和玻璃纖維螺距一致，纏繞均勻。通風管道的彎曲合理。只要符合工程要求，可以用相當數量的材料代替，比如我們在通風工程中經常使用的帆布。不銹鋼風管具有更強的耐溫性和耐腐蝕性。還具有耐溫阻燃的作用。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">地下室的通風方式應合理布置排氣管和出風口，平時使用。發生火災時，還可用作排煙管和排煙口；地下一層是巷道自然通風，其他樓層是平時的送風系統。各排風、排煙、送風系統均設豎井，進風口設在地面潔凈處。</span></p><p style="text-align: center; text-indent: 2em;"><img
