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(diào)工程中使用的金屬及非金屬、薄壁圓形通風管道或復(fù)合材料風管的加工、生產(chǎn)質(zhì)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(zhì)量驗收，按照設(shè)計圖紙和本規(guī)范的規(guī)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(yīng)的產(chǎn)品資質(zhì)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(zhì)量按其材料、系統(tǒng)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(guī)格、強度、密封性和外觀質(zhì)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(yīng)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(yīng)滿足使用環(huán)境的要求，密封面應(yīng)設(shè)置在薄壁圓形通風管道正壓側(cè)。

　　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(fù)合保護層的鋼板，應(yīng)采用咬接或鉚接，不應(yīng)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(nèi)外壁薄壁圓形風管光滑，風管阻力小，送風、排風不產(chǎn)生二次噪聲，降低能耗，節(jié)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.
