Before assembling the spiral air duct, you need to do a lot of preparatory work, and contact the actual situation to inquire the actual installation method on the spot. We can explain in detail the basic standards of Ningbo ventilation duct (Galvanized spiral pipe, stainless steel spiral pipe and thin iron spiral pipe). In fact, they can all have normal structure. You can also understand some common constructors. You can also explain the material of the pipeline and how to use it in the drawing.

针对更繁杂的工业建筑，在开发阶段，每一种类别划到（暖通空调，供水和排水，配电照明灯具和房屋建筑）应首要商谈室内空间分离出来并明确每一种类别管路的高程范围。在相对的情形下，你不能超过为自己调节的限定。假如单独一个管段穿行界限，则应资询别的项目。

For more complex industrial buildings, in the development stage, each category (HVAC, water supply and drainage, power distribution, lighting fixtures and house buildings) shall be divided into indoor space and the elevation range of each category of pipeline shall be determined. In a relative situation, you can't exceed the limit of adjusting for yourself. If a single pipe section crosses the boundary, other items shall be consulted.

工程施工前，假如工程施工流程中发生一切问题，机器设备负责人的技术工程师应当详细寻找技术工程师。假如您可以在相同总平面图上制作管路和单线，可以根据地域分他们。Z好能够更好地解释，假如能及时处理问题，可以一切正常处理这种问题，这十分关键。

Before the project construction, if all problems occur in the project construction process, the technical engineer of the person in charge of machinery and equipment shall look for the technical engineer in detail. If you can make pipelines and single lines on the same general plan, you can divide them according to region. Z good can better explain. If we can deal with the problem in time, we can deal with this problem normally, which is very key.

宁波螺旋风管在工程施工中值得注意点是什么？

What are the noteworthy points of Ningbo spiral air duct in engineering construction?

处理各种各样慈溪通风风管撞击协调的基本原理，通常是：“小管路容许大管路，有工作压力使无工作压力”。比如，假如自来水管与气体管路撞击，则应旋转自来水管。假如冷水管和自来水管与下方自来水管产生撞击，应拆换冷水热水管。

The basic principle of dealing with the impact coordination of various Cixi ventilation air ducts is usually: "small pipe allows large pipe, with working pressure so that there is no working pressure". For example, if the water pipe collides with the gas pipeline, the water pipe should be rotated. If the cold water pipe and tap water pipe collide with the tap water pipe below, the cold water and hot water pipe shall be removed and replaced.

此外，很有必要对应用的地域做好深入分析，哪一个地域更快，假如能系统化的解释通风风管的情形，应用时也更快。现在它被用于很多工业企业，涉及到的行业的确十分普遍。应当能够更好地解释它是怎么使用的。

In addition, it is necessary to make an in-depth analysis of the application area. Which area is faster? If the situation of ventilation duct can be explained systematically, the application is also faster. Now it is used in many industrial enterprises, and the industries involved are indeed very common. It should be able to better explain how it is used.

工程施工前，机器设备负责人技术工程师应在单层总平面图上划到各类划到线。每一种类别的管路都应用彩色笔。螺旋风管厂家为了更好地降低投資，节约室内空间，降低地板相对高度，可以根据承重梁（如自来水管，吐火管等）铺装部分无倾斜度的管路。

Before the construction of the project, the person in charge of machinery and equipment and the technical engineer shall draw various lines on the single floor general plan. Color pens shall be used for each type of pipe. In order to better reduce investment, save indoor space and reduce the relative height of the floor, spiral duct manufacturers can pave some non inclined pipelines according to the load-bearing beams (such as water pipe, fire spitting pipe, etc.).

简单点来说，不管在什么情况，当你挑选通风管道时，你需要看什么能充分发挥更快的功效。可以在特殊供汽管路上播出的作用很好。开发阶段应当更清晰地解释，保护可以一切正常应用并充分发挥更快的功效，这也是关键环节，也是我们都想要知道的部分基本情况。

Simply put, no matter what the situation, when you choose the ventilation duct, you need to see what can give full play to the faster effect. It can play a good role in special steam supply pipeline. In the development stage, it should be explained more clearly that protection can be used normally and give full play to its faster effect. This is also the key link and part of the basic information we all want to know.
