我相信很多人不知道什么是鐵風管，這是一種通風風管，可以幫助氣體的運輸和循環。雖然這些人接觸的機會較少，但它們為生活提供了很大的幫助。鍍鋅風管系統完成后，須進行相應的檢查，以有效保證鐵皮風管的質量和使用效果。讓我們來看看實際的檢查工作：
I believe many people don't know what iron air duct is. It is a kind of ventilation air duct, which can help the transportation and circulation of gas. Although these people have less access, they provide a lot of help for life. After the completion of galvanized air duct system, corresponding inspection must be carried out to effectively ensure the quality and use effect of iron sheet air duct. Let's take a look at the actual inspection work:
1.鐵皮通風管道的強度應滿足1.5倍工作壓力下接縫處無裂紋；
1. The strength of iron sheet ventilation pipe shall meet the requirement that there is no crack at the joint under 1.5 times the working pressure;
2.采用漏光法監控系統風管嚴格水平：選擇一定強度的安全燈源沿檢查接口位置和接頭緩慢移動，在另一側進行觀察檢查，做好記錄，發現接頭泄漏需要密封；當選擇泄漏法監控系統密封時，低壓系統風管每10m接縫，漏光點不大于2處，且1OOm接縫平均值不大于16為合格；高壓系統風管每10m接縫，漏光點不大于1，OOm接縫均值不大于8處為合格；
2. Use the light leakage method to monitor the strict level of the air duct of the system: select a certain intensity of safety light source to move slowly along the inspection interface position and joint, observe and check on the other side, make records, and find that the joint leakage needs to be sealed; When the leakage method monitoring system is selected for sealing, it is qualified that the light leakage point of the low-pressure system air duct is no more than 2 per 10m joint, and the average value of the 1OOm joint is no more than 16; For every 10m joint of the air duct of the high-pressure system, the light leakage point is not more than 1, and the average value of the oom joint is not more than 8;
3.系統漏風檢測可以整體或分段進行。檢測時，被測系統的所有開口應關閉，不得漏風。當漏風量超過設計和驗收規范要求時，可以聽.摸.觀查.水或煙泄漏，找出漏風位置，做好標識；修好后，再次檢測，直至合格。
3. The air leakage detection of the system can be carried out as a whole or in sections. During the test, all openings of the tested system shall be closed without air leakage. When the air leakage exceeds the requirements of design and acceptance specifications, you can listen Touch Observation If water or smoke leaks, find out the air leakage position and make a mark; After repair, test again until it is qualified.
The above is a detailed introduction about the ventilation ducts in Jinan. I hope it will help you If you have any questions, please contact us We will provide you with professional service http://www.rps-infinia.com
