Thickness and specification of thin-walled circular ventilation pipe can be adjusted according to requirements. When connecting pipes, the two ends are always connected from outside with attachments. Ventilation pipe manufacturer reminds us to pay attention to the relevant regulations when making thin-walled circular ventilation pipe:

　　1. 適用于建筑工程通風空調工程中使用的金屬及非金屬、薄壁圓形通風管道或復合材料風管的加工、生產質量的驗收。

　　1. Suitable for processing and acceptance of production quality of metal and non-metal, thin-walled circular ventilation ducts or composite ducts used in ventilation and air conditioning engineering of building engineering.

　　2. 薄壁圓形通風管道的制造質量驗收，按照設計圖紙和本規范的規定進行。本工程選用的外包薄壁圓形通風管道，必須提供相應的產品資質或強度、密性驗證文件，并符合要求后方可使用。

　　2. Inspection and acceptance of manufacturing quality of thin-walled circular ventilation ducts shall be carried out in accordance with the design drawings and the provisions of this Code. The thin-walled circular ventilation pipes selected in this project must provide the corresponding product qualification or strength and tightness verification documents, and can be used only after meeting the requirements.

　　3.對薄壁圓形通風管道的制造質量按其材料、系統類別和使用場所進行驗收，主要包括薄壁圓形通風管道成品的材料、規格、強度、密封性和外觀質量。

　　3. Acceptance and acceptance of the manufacturing quality of thin-walled circular ventilation pipeline according to its material, system type and place of use, mainly including the material, specification, strength, sealing and appearance quality of the finished product of thin-walled circular ventilation pipeline.

　　4、薄壁圓形通風管道的密封，應是板連接的密封，可采用密封劑嵌縫等密封方法。密封膠性能應滿足使用環境的要求，密封面應設置在薄壁圓形通風管道正壓側。

　　4. The sealing of thin-walled circular ventilation pipeline should be plate-connected, and sealing methods such as sealant seam can be used. Sealant performance should meet the requirements of the use environment, and the sealing surface should be set at the positive pressure side of the thin-walled circular ventilation pipeline.

　　5、鍍鋅鋼板和各種含有復合保護層的鋼板，應采用咬接或鉚接，不應影響保護層的耐腐蝕焊接方法。

　　5. Galvanized steel sheets and various steel sheets with composite protective coatings should be bitten or riveted, which should not affect the corrosion-resistant welding method of protective coatings.

　　內外壁薄壁圓形風管光滑，風管阻力小，送風、排風不產生二次噪聲，降低能耗，節約運行成本。

　　The inner and outer wall thin-walled circular air duct is smooth, the resistance of the air duct is small, the secondary noise of the air supply and exhaust is not produced, the energy consumption is reduced, and the operation cost is saved.
