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(fēng)管道的強(qiáng)度應(yīng)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(jiān)控系統(tǒng)風(fēng)管嚴(yán)格水平：選擇一定強(qiáng)度的安全燈源沿檢查接口位置和接頭緩慢移動(dòng)，在另一側(cè)進(jìn)行觀察檢查，做好記錄，發(fā)現(xiàn)接頭泄漏需要密封；當(dāng)選擇泄漏法監(jiān)控系統(tǒng)密封時(shí)，低壓系統(tǒng)風(fēng)管每10m接縫，漏光點(diǎn)不大于2處，且1OOm接縫平均值不大于16為合格；高壓系統(tǒng)風(fēng)管每10m接縫，漏光點(diǎn)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(tǒng)漏風(fēng)檢測(cè)可以整體或分段進(jìn)行。檢測(cè)時(shí)，被測(cè)系統(tǒng)的所有開口應(yīng)關(guān)閉，不得漏風(fēng)。當(dāng)漏風(fēng)量超過設(shè)計(jì)和驗(yàn)收規(guī)范要求時(shí)，可以聽.摸.觀查.水或煙泄漏，找出漏風(fēng)位置，做好標(biāo)識(shí)；修好后，再次檢測(cè)，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.
