一般在設(shè)備的時(shí)分許多人為了減低通風(fēng)工程的費(fèi)用，會(huì)挑選較薄的資料，縱使這樣關(guān)于螺旋風(fēng)管的強(qiáng)度也絕不會(huì)有很大的影響，因?yàn)槁菪L(fēng)管有骨，能夠前進(jìn)百分之三十的強(qiáng)度。一般螺旋風(fēng)管的保溫辦法，是通過運(yùn)用內(nèi)貼保溫資料進(jìn)行保溫的，這樣的規(guī)劃不光能夠體現(xiàn)風(fēng)管的外表，而且不會(huì)遮擋天花板，能夠大程度的減低工程費(fèi)用的本錢。

Generally, when using equipment, many people choose thinner materials to reduce the cost of ventilation engineering. Even so, the strength of spiral air ducts will not have a significant impact because spiral air ducts have bones that can increase their strength by 30%. The general insulation method for spiral air ducts is to use internal insulation materials for insulation. This planning not only reflects the appearance of the duct, but also does not block the ceiling, which can greatly reduce the cost of the project.

也能夠挑選防火保溫風(fēng)管，這是一種高新科技能源資料，具有多類優(yōu)異的特色，不光體現(xiàn)在保溫特色杰出這方面，除此之外能夠很低的漏風(fēng)率，前進(jìn)空氣輸出功率，下降抵觸耗損，防火保溫風(fēng)管在的特色上也是特其他超卓，它能夠帶來清潔空氣，然后前進(jìn)室內(nèi)空氣質(zhì)量，而且具有減低噪聲，堅(jiān)持環(huán)境安靜的利益。

It is also possible to choose fire-resistant and insulated air ducts, which are a high-tech energy material with multiple excellent characteristics. This is not only reflected in the outstanding insulation characteristics, but also in the low air leakage rate, forward air output power, and reduced resistance to wear and tear. The fire-resistant and insulated air ducts are also outstanding in their characteristics. They can bring clean air, improve indoor air quality, and reduce noise, The benefit of maintaining a quiet environment.

依照動(dòng)工現(xiàn)場的實(shí)踐情形，能夠先把風(fēng)管一節(jié)一節(jié)地放在支架上逐節(jié)聯(lián)接，也能夠先在地表上聯(lián)接成的長度，然后挑選全體吊裝辦法設(shè)備就行了，這便是螺旋風(fēng)管的接長吊裝法。

According to the practical situation at the construction site, it is possible to first place the air ducts section by section on the support and connect them one by one, or connect them to a certain length on the ground, and then select all the lifting methods and equipment. This is the spiral air duct extension lifting method.

值得留神的是邊長或比直徑大于1250毫米的風(fēng)管吊裝時(shí)不能逾越3節(jié)，邊長或比直徑假設(shè)小于1250毫米的風(fēng)管組合吊裝時(shí)，不能逾越3節(jié)，當(dāng)風(fēng)管聯(lián)接好放在支吊架上后，然后聯(lián)接好托盤及吊桿，判定好風(fēng)管現(xiàn)已穩(wěn)固健壯后，解開繩扣就行了。

It is worth noting that when hoisting air ducts with a side length or specific diameter greater than 1250 millimeters, they cannot exceed 3 sections. When hoisting air ducts with a side length or specific diameter assumed to be less than 1250 millimeters, they cannot exceed 3 sections. After the air ducts are connected and placed on the support and hanger, the tray and hanger are connected, and it is determined that the air ducts are now stable and robust. After that, the rope buckle is loosened.
