一般在設備的時分許多人為了減低通風工程的費用，會挑選較薄的資料，縱使這樣關于螺旋風管的強度也絕不會有很大的影響，因為螺旋風管有骨，能夠前進百分之三十的強度。一般螺旋風管的保溫辦法，是通過運用內貼保溫資料進行保溫的，這樣的規劃不光能夠體現風管的外表，而且不會遮擋天花板，能夠大程度的減低工程費用的本錢。

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管，這是一種高新科技能源資料，具有多類優異的特色，不光體現在保溫特色杰出這方面，除此之外能夠很低的漏風率，前進空氣輸出功率，下降抵觸耗損，防火保溫風管在的特色上也是特其他超卓，它能夠帶來清潔空氣，然后前進室內空氣質量，而且具有減低噪聲，堅持環境安靜的利益。

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.

依照動工現場的實踐情形，能夠先把風管一節一節地放在支架上逐節聯接，也能夠先在地表上聯接成的長度，然后挑選全體吊裝辦法設備就行了，這便是螺旋風管的接長吊裝法。

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毫米的風管吊裝時不能逾越3節，邊長或比直徑假設小于1250毫米的風管組合吊裝時，不能逾越3節，當風管聯接好放在支吊架上后，然后聯接好托盤及吊桿，判定好風管現已穩固健壯后，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.
