　　通風工程中風管制作與安裝需要注意的細節涵蓋了多個方面，以下是根據公開發布的信息整理的一些關鍵要點：

　　The details that need to be paid attention to in the production and installation of air ducts in ventilation engineering cover multiple aspects. The following are some key points compiled based on publicly released information:

　　風管制作細節

　　Details of air duct production

　　材料選擇：

　　Material selection:

　　風管材料應符合設計和國家產品標準的規定，如鋼板或鍍鋅鋼板的厚度需達到規定要求。

　　The material of the air duct should comply with the design and national product standards, such as the thickness of steel plates or galvanized steel plates meeting the specified requirements.

　　防火風管的本體、框架與固定材料、密封墊料必須為不燃材料，耐火等級需符合設計要求。

　　The body, frame, fixing materials, and sealing gasket of the fireproof air duct must be non combustible materials, and the fire resistance rating must meet the design requirements.

　　制作工藝：

　　Production process:

　　應采用咬口連接或鉚接，避免焊接，以保證連接處的強度和密封性。

　　Biting or riveting should be used to avoid welding and ensure the strength and sealing of the connection.

　　風管板材拼接的咬口縫應錯開，不得有十字型拼接縫，咬口縫需緊密、寬度一致。

　　The seams of the air duct panels should be staggered and there should be no cross shaped seams. The seams should be tight and of consistent width.

　　風管表面應平整，無明顯扭曲與翹角，凹凸誤差控制在規定范圍內（如8mm以內）。

　　The surface of the air duct should be flat, without obvious distortion or warping, and the unevenness error should be controlled within the specified range (such as within 8mm).

　　對于尺寸較大的矩形風管或保溫風管，以及長度超過一定限制的低、中、高壓風管，應采取加固措施。

　　For large-sized rectangular ducts or insulated ducts, as well as low, medium, and high-pressure ducts with lengths exceeding certain limits, reinforcement measures should be taken.

　　法蘭制作與連接：

　　Flange fabrication and connection:

　　法蘭加工應采用模具法，以保證法蘭的互換性和尺寸精度。

　　The flange processing should adopt the mold method to ensure the interchangeability and dimensional accuracy of the flange.

　　法蘭平面度的允許偏差、矩形法蘭兩對角線之差以及螺孔間距等均需符合規定。

　　The allowable deviation of flange flatness, the difference between the two diagonals of rectangular flanges, and the spacing between screw holes must all comply with regulations.

　　風管與法蘭連接時，翻邊寬度需達到規定要求（如6mm以上），翻邊應均勻平整且緊貼法蘭。

　　When connecting the air duct to the flange, the flange width should meet the specified requirements (such as 6mm or more), and the flange should be evenly, smoothly, and tightly attached to the flange.

　　成品保護：

　　Finished product protection:

　　風管半成品、成品應整齊地放置在方木上，避免多層堆放導致變形。

　　The semi-finished and finished air ducts should be neatly placed on square wood to avoid deformation caused by multiple layers of stacking.

　　長時間堆放的風管成品應用塑料薄膜覆蓋，以防止積灰和受潮。

　　Long term stacked finished air ducts should be covered with plastic film to prevent dust accumulation and moisture.

　　在搬運裝卸過程中應輕拿輕放，避免損壞成品。

　　During the handling and loading process, handle with care to avoid damaging the finished product.

　　風管安裝細節

　　Installation details of air duct

　　安裝前準備：

　　Preparation before installation:

　　核對圖紙與現場，確認能否按設計標高和位置進行安裝。

　　Check the drawings with the site to confirm if installation can be carried out according to the design elevation and position.

　　清除風管內外雜物，并做好清潔和保護工作。

　　Clear the debris inside and outside the air duct, and do a good job of cleaning and protection.

　　支吊架安裝：

　　Installation of supports and hangers:

　　支吊架應使用角鋼等堅固材料制作，膨脹螺栓的位置應正確、牢固可靠。

　　The support and hanger should be made of sturdy materials such as angle steel, and the position of the expansion bolt should be correct, firm, and reliable.

　　支吊架的間距應根據風管尺寸和安裝要求確定，并統一設定。

　　The spacing between supports and hangers should be determined according to the size of the air duct and installation requirements, and set uniformly.

　　支吊架不得設在風口、閥門、檢查門及自控機構處，離風口或插接管的距離需符合規定。

　　Support hangers shall not be installed at air vents, valves, inspection doors, and self-control mechanisms, and the distance from air vents or plug-in pipes shall comply with regulations.

　　風管連接與安裝：

　　Duct connection and installation:

　　風管接口的連接應嚴密、牢固，法蘭間的墊片需符合系統功能要求。

　　The connection of the air duct interface should be tight and firm, and the gasket between the flanges should meet the functional requirements of the system.

　　風管安裝時應確保中心線處于水平狀態，每安裝一段風管后都需進行水平測量。

　　When installing the air duct, it should be ensured that the centerline is in a horizontal state, and horizontal measurements should be taken after installing each section of the air duct.

　　當風管長度超過一定長度時（如20米），需設置防晃支架。

　　When the length of the air duct exceeds a certain length (such as 20 meters), anti sway brackets need to be installed.

　　特殊部位處理：

　　Special part treatment:

　　當風管需要穿過封閉的防火或防爆墻體或樓板時，應預先埋設管子或防護套管，并使用不燃且對人體無害的柔性材料進行封堵。

　　When air ducts need to pass through enclosed fire-resistant or explosion-proof walls or floors, pipes or protective sleeves should be pre buried and sealed with non combustible and harmless flexible materials.

　　防火排煙風管的支吊架必須單獨設置，同時支管、管道式消聲器、消聲器彎頭以及防火閥也必須單獨設置支、吊架。

　　The supports and hangers for fire and smoke exhaust ducts must be separately installed, and the branch pipes, pipe type mufflers, muffler elbows, and fire dampers must also be separately supported and hung.

　　安裝后檢查與驗收：

　　Inspection and acceptance after installation:

　　風管安裝完成后，應按照系統壓力等級進行嚴密性檢驗。

　　After the installation of the air duct is completed, a tightness test should be conducted according to the system pressure rating.

　　檢查風管內部是否清潔無雜物，支吊架是否牢固可靠。

　　Check whether the interior of the air duct is clean and free of debris, and whether the supports and hangers are firm and reliable.

　　確認風管的位置、標高、走向是否符合設計要求。

　　Confirm whether the position, elevation, and direction of the air duct meet the design requirements.

　　其他注意事項

　　Other precautions

　　在整個制作與安裝過程中，應嚴格遵守相關安全規范和操作規程，確保人員和設備的安全。

　　Throughout the entire production and installation process, relevant safety regulations and operating procedures should be strictly followed to ensure the safety of personnel and equipment.

　　對于特殊環境下的風管制作與安裝（如高溫、潮濕、腐蝕性等環境），需采取額外的防護措施和特殊要求。

　　For the production and installation of air ducts in special environments (such as high temperature, humidity, corrosive environments, etc.), additional protective measures and special requirements need to be taken.

　　風管制作與安裝完成后，應及時進行記錄和歸檔，以便后續維護和檢修。

　　After the production and installation of air ducts are completed, they should be recorded and archived in a timely manner for subsequent maintenance and repair.

　　綜上所述，通風工程中風管制作與安裝需要注意的細節眾多，涵蓋了材料選擇、制作工藝、成品保護、安裝前準備、支吊架安裝、風管連接與安裝、特殊部位處理以及安裝后檢查與驗收等多個方面。只有嚴格遵守相關規范和要求，才能確保風管制作與安裝的質量和安全。

　　In summary, there are numerous details that need to be paid attention to in the production and installation of air ducts in ventilation engineering, including material selection, production process, finished product protection, pre installation preparation, support and hanger installation, air duct connection and installation, special part treatment, and post installation inspection and acceptance. Only by strictly adhering to relevant regulations and requirements can the quality and safety of air duct production and installation be ensured.
