Generally, it is also called: air duct, ventilation duct, mechanical air duct, ventilation duct, white iron air duct, galvanized air duct, stainless steel air duct, air duct processing, white iron processing, galvanized iron sheet air duct production, galvanized iron sheet air duct, iron sheet air duct, white iron sheet air duct, ventilation duct company, ventilation duct design, ventilation duct installation, ventilation duct processing, white iron sheet ventilation duct, ventilation duct components

对于比较复杂的民用建筑，在设计阶段，各工种(暖通、给水排水，供电照明与建筑)应协商好空间分隔，定出每种蜜桃成人在线精品视频的标高范围。一般情况下不得越出给自己规定的界限。遇有个别管段要越界时应与其他工程协商。

For more complex civil buildings, in the design phase, all types of work (HVAC, water supply and drainage, power supply and lighting and architecture) should first negotiate space separation and determine the elevation range of each type of pipe. In general, you should not exceed the limits set for yourself. In case of pipeline section crossing the boundary, it shall negotiate with other projects.

解决各种通风蜜桃成人在线精品视频相碰及协调的原则，一般为:“小管让大管，有压让无压”。例如，自来水管与风管相撞，则应当自来水管拐弯。冷、热水管与下水管相碰。则应改变冷、热水蜜桃成人在线精品视频。

The principle to solve the collision and coordination of various ventilation pipes is generally: "small pipes give way to large ones, and pressure gives way to no pressure". For example, if the water pipe collides with the air pipe, the water pipe should turn. The cold and hot water pipes collide with the sewer pipes. The cold and hot water pipes shall be changed.

施工前应设备总管的工程师，将各工种的管线，单线画在一张平面图上。每种蜜桃成人在线精品视频用一种彩色笔。在各交点处综合其标高，看是否有矛盾之处，及时发现，将问题解决在安装之前。

Before construction, the engineer in charge of equipment shall draw the pipelines and single lines of each type of work on a plan. One color pen for each type of pipe. The elevation of each intersection shall be integrated to see if there is any contradiction, and the problem shall be solved before installation.

为了减少投资，节省空间，降低层高，有些敷设无坡度要求的蜜桃成人在线精品视频，可以穿梁敷设(如自来水蜜桃成人在线精品视频，消防喷洒干管等)。

In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams (such as water supply pipes, fire sprinkler main pipes, etc.).
