螺旋风管是一种由金属带卷成螺旋缝的薄壁管
螺旋风管和普通的通风管道有什么区别？
What is the difference between spiral ducts and regular ventilation ducts? The ventilation duct manufacturer will explain to you:
螺旋风管是一种由金属带卷成螺旋缝的薄壁管。它是圆的。其主要特点是：无焊接、无漏气、无漏水。它主要用于送风和散料运输，而不是传统的白口铁管(即手工咬缝铁管)。它是一种风道，不需要用手敲打。
Spiral duct is a thin-walled pipe made of metal strips rolled into spiral seams. It is round. Its main characteristics are: no welding, no air leakage, and no water leakage. It is mainly used for air supply and bulk material transportation, rather than traditional white iron pipes (i.e. hand sewn iron pipes). It is a type of air duct that does not require manual tapping.
(1)送风，包括通风，如新风的供应和排风，覆盖范围广泛，如工厂车间和生产现场。由于有害气体的产生，有必要将室外空气排放到室内，并将室外空气输送到室内。
(1) Air supply, including ventilation, such as the supply and exhaust of fresh air, covers a wide range of areas, such as factory workshops and production sites. Due to the generation of harmful gases, it is necessary to exhaust outdoor air indoors and transport outdoor air indoors.
(2)供冷。常见的是空调管道，它需要保温材料。
(2) Cooling. The common one is the air conditioning pipeline, which requires insulation materials.
(3)排烟。宾馆、饭店和宾馆的厨房都有大量的油烟，需要排放。使用的圆形风管是油烟筒。
(3) Smoke exhaust. Hotels, restaurants, and hotel kitchens all have a large amount of oil fumes that need to be emitted. The circular air duct used is a range hood.
(4)除尘。在一些工厂，车间里有很多灰尘，需要特殊的除尘设备。螺旋风管适用于风量较大的管道。
(4) Dust removal. In some factories, there is a lot of dust in the workshop and special dust removal equipment is needed. Spiral air ducts are suitable for ducts with high air volume.
(5)散料运输。在一些厂的生产过程中，需要运输松散的颗粒，特别是比例较小的颗粒，如泡沫塑料颗粒，采用螺旋风管，成本低，效果好。
(5) Bulk material transportation. In the production process of some factories, it is necessary to transport loose particles, especially particles with small proportion, such as foam plastic particles. Spiral air ducts are used, which have low cost and good effect.
通风管道:
Ventilation ducts:
1.独特的设计:在通风管道的开口上安装烟气止回阀和防火隔离门，有效防止交叉气味和交叉火灾。
1. Unique design: Install smoke check valves and fire isolation doors on the openings of ventilation ducts to effectively prevent cross odors and cross fires
