螺旋管环缝,接头的强度远高于直缝径向的强度,所以能保证1.5倍工作压力下的缝,没有裂缝,由于其原材料镀锌带钢与整块镀锌钢相比,价格低,工厂生产和标准化的规范,使低成本比矩形管;另外，由于所需的支架和吊架数量少，安装工作量小，所以总成本相对较低。由于矩形风道四角容易产生湍流，有效流动面积减小，气流良好，有效流动面积大，所以产品的二次噪声小，因为其强度大。因此，风管振动引起的低频噪声越小，气流性能越好，系统的压降越小，日常运行系统的功耗越小。通过风管成型机将咬骨成型，并沿螺旋渐开线轨道滚成圆形的管状，同时将咬骨缝压缩，按要求的长度切割。自推出以来，以其优异的性能和低廉的运行成本，广泛应用于造船、通风、空调、净化、桥梁除尘、机场、隧道等建筑行业。冷热空气更常见的来源是空调，它需要保温。也可将保温材料贴在里面，使风道具有螺旋形的美观外形，可避免吊顶，从而降低了工程造价。山东螺旋风管生产高度自动化,生产速度是非常快,一般风管每分钟可生产20 ~ 40米,由于其原材料镀锌带钢,镀锌钢板,价格较低,加上其工厂生产和规范标准化,成本低于矩形管。
The strength of spiral pipe ring seam and joint is much higher than that of straight seam radial, so it can ensure the seam under 1.5 times of working pressure without cracks. Compared with the whole piece of galvanized steel, the raw material galvanized steel strip has low price, factory production and standardized specifications, which makes the cost lower than rectangular pipe. In addition, due to the small number of supports and hangers required and small installation work, the total cost is relatively low. Because the four corners of the rectangular air duct are easy to produce turbulence, the effective flow area is reduced, the air flow is good, and the effective flow area is large, so the secondary noise of the product is small because of its high intensity. Therefore, the lower the low-frequency noise caused by the duct vibration, the better the air flow performance, the smaller the pressure drop of the system, and the smaller the power consumption of the daily operation system. The undercut is formed by the air tube forming machine and rolled into a circular tube along the spiral involute track. Meanwhile, the undercut seam is compressed and finally cut according to the required length. Since its introduction, it has been widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airport, tunnel and other construction industries with its excellent performance and low operating cost. The most common source of hot and cold air is central air conditioning, which needs to be insulated. The insulation material can also be pasted inside, so that the air duct has a beautiful spiral shape, and the ceiling can be avoided, thus reducing the project cost. Shandong spiral air duct production is highly automated, the production speed is very fast, the general air duct can produce 20 ~ 40 meters per minute, because of its raw material galvanized steel strip, galvanized steel plate, the price is low, coupled with its factory production and standardization, the cost is lower than rectangular pipe.
If advanced technology and equipment are used and processing equipment corresponding to other processes are equipped, the process and quality of air conditioning pipeline processing progress will be improved. However, in the process of multi-step processing of attributes, a lot of manpower is still needed to rotate operation in multiple equipment, scale, and processing efficiency and quality of air duct are still in a low stage. Fortunately, after using the common plate flange connection technology, the processing process of air conditioning duct not only reduces the working procedure, but also saves some manual operation procedures, and also requires cutting, corner cutting, reinforcement, common plate flange forming, corner joint and assembly and other processes.
The spiral air duct has a precise pressing process, which enables the spiral air duct in Shandong Province to withstand the strongest pressure. The thickness of the potential joint is four times that of the pipe body. The rigidity of the pipe is very large, showing the advantage of firmness. This greatly reduces the cost of production. In addition, what we need to tell you is that the production process of Shandong spiral air duct is very complex. It is usually made of special steel, so it can guarantee the natural quality, which can be used for several years generally. It can also guarantee the long-term use of deformation, greatly extend the service life of the pipeline, which has important practical significance for our production.
