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.
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.
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.
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.上一篇：不锈钢风管毁坏怎么处理比较好？
