管道风机在很多行业有着广泛的应用,通风管道应用广泛的原因跟他的特点是分不开的螺旋厂房通风管道市场上按材质一般分为三类:镀锌螺旋风管、不锈钢螺旋风管以及复合螺旋风管。其中,不锈钢风管质量,适用性强,但高。目前市场通广的螺旋风管是镀锌板的。镀锌板螺旋风管,基本是不锈钢螺旋风管的特性,但是相对只有不锈钢风管的三分之二甚更低。复合螺旋风管一般应用在外界环境较为普通,对风管要求不太高的场所。由于铁皮容易在各种环境下发生化学反应,造成腐蚀、生锈。而锌在干燥的空气中几乎不发生变化。在潮湿的空气中,锌表面会生成致密的碱式碳酸锌膜。螺旋风管主要是在风管铁皮上镀上一层锌,对铁皮起到保护的作用。锌镀层经钝化处理、染色或涂覆护光剂后,能显著提高其防护性和装饰性。
Pipeline fans are widely used in many industries, and the reason for the widespread use of ventilation ducts is closely related to their characteristics. In the spiral factory ventilation duct market, they are generally divided into three categories based on material: galvanized spiral duct, stainless steel spiral duct, and composite spiral duct. Among them, stainless steel air ducts are of high quality and applicability, but their prices are high. At present, the widely circulated spiral air duct in the market is made of galvanized sheet. Galvanized sheet spiral air duct is basically a characteristic of stainless steel spiral air duct, but its price is relatively only two-thirds or even lower than that of stainless steel air duct. Composite spiral air ducts are generally used in places with ordinary external environments and low requirements for air ducts. Due to the susceptibility of iron sheet to chemical reactions in various environments, it can cause corrosion and rusting. And zinc hardly changes in dry air. In humid air, dense basic Zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with a layer of zinc on the iron sheet of the air duct, which plays a protective role on the iron sheet. The zinc coating can significantly improve its protective and decorative properties after passivation treatment, dyeing, or coating with protective agents.
通风管道不锈钢风管特点介绍:
Introduction to the characteristics of stainless steel air ducts in ventilation ducts:
1、外形美观、内壁光滑、阻力小、气密性好、承压强度高,能适合非常复杂的排气工程
1. Beautiful appearance, smooth inner wall, low resistance, good airtightness, high compressive strength, suitable for very complex exhaust engineering

2、可排除可燃及不可燃之化学腐蚀气体,而不需要另外装置洒水灭火设备。
2. It can eliminate flammable and non combustible chemical corrosive gases without the need for additional sprinkler fire extinguishing equipment.
3、由不锈钢制成,材质坚固,易保持完整性。。
3. Made of stainless steel, the material is sturdy and easy to maintain integrity..
目前市场通广的螺旋风管是镀锌板的螺旋厂房通风管道螺旋咬缝薄壁管,早是瑞士发明的螺旋风管,螺旋风管应用于西方的军工业,如军舰、轮船排(送)风系统,后来用于火车、地铁、矿山等民用设施。螺旋厂房通风管道在一些外资、合资企业中率先使用。、由于螺旋风管有骨(螺旋形咬缝)可提高强度30%,故可选用较薄的材料,比如0.8毫米的厚度可改为0.6毫米,另外在同样截面积的情况下,采用螺旋风管可节省材料20%。由于铁皮容易在各种环境下发生化学反应,造成腐蚀、生锈。而锌在干燥的空气中几乎不发生变化。在潮湿的空气中,锌表面会生成致密的碱式碳酸锌膜。螺旋风管主要是在风管铁皮上镀上一层锌,对铁皮起到保护的作用。锌镀层经钝化处理、染色或涂覆护光剂后,能显著提高其防护性和装饰性。。
At present, the widely circulated spiral air duct in the market is a galvanized sheet spiral factory ventilation duct with spiral seam thin-walled pipes, which was invented by Switzerland. Spiral air ducts were first applied to military industries in Western countries, such as warships and ship exhaust (supply) air systems, and later used in civilian facilities such as trains, subways, and mines. Spiral factory ventilation ducts were first used in some foreign and joint venture enterprises Due to the fact that the spiral duct has a bone (spiral seam) that can increase its strength by 30%, thinner materials can be selected, such as a thickness of 0.8 millimeters that can be changed to 0.6 millimeters. In addition, using spiral ducts can save 20% of the material under the same cross-sectional area. Due to the susceptibility of iron sheet to chemical reactions in various environments, it can cause corrosion and rusting. And zinc hardly changes in dry air. In humid air, dense basic Zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with a layer of zinc on the iron sheet of the air duct, which plays a protective role on the iron sheet. The zinc coating can significantly improve its protective and decorative properties after passivation treatment, dyeing, or coating with protective agents..
