一般在设备的时分许多人为了减低通风工程的费用，会挑选较薄的资料，纵使这样关于螺旋风管的强度也绝不会有很大的影响，因为螺旋风管有骨，能够前进百分之三十的强度。一般螺旋风管的保温办法，是通过运用内贴保温资料进行保温的，这样的规划不光能够体现风管的外表，而且不会遮挡天花板，能够大程度的减低工程费用的本钱。

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.

也能够挑选防火保温风管，这是一种高新科技能源资料，具有多类优异的特色，不光体现在保温特色杰出这方面，除此之外能够很低的漏风率，前进空气输出功率，下降抵触耗损，防火保温风管在的特色上也是特其他超卓，它能够带来清洁空气，然后前进室内空气质量，而且具有减低噪声，坚持环境安静的利益。

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.

依照动工现场的实践情形，能够先把风管一节一节地放在支架上逐节联接，也能够先在地表上联接成的长度，然后挑选全体吊装办法设备就行了，这便是螺旋风管的接长吊装法。

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.

值得留神的是边长或比直径大于1250毫米的风管吊装时不能逾越3节，边长或比直径假设小于1250毫米的风管组合吊装时，不能逾越3节，当风管联接好放在支吊架上后，然后联接好托盘及吊杆，判定好风管现已稳固健壮后，解开绳扣就行了。

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.
