  普通冷轧钢板:价格便宜、易腐蚀 ,一般通风用送风、回风、新风、排风、排烟系统。镀锌钢板: 耐腐蚀性相比刚办好,但在加工过程中铁皮 对温湿度要求较高场合的送回风系统,超净系统中效过滤,易脱落,油漆不易附着 器前和中效至高效过滤器之间的送风系统。铝合金板:不起尘、价格贵, 30级净化系统高效过滤器之后送风系统。

  Ordinary cold-rolled steel plate: cheap, easy to corrode, general ventilation with air supply, return air, fresh air, exhaust air, smoke exhaust system. Galvanized steel sheet: Corrosion resistance is better than just done, but in the process of processing iron sheet on high temperature and humidity requirements occasions of air supply and return system, ultra-clean system effective filtration, easy to fall off, paint is not easy to attach to the pre-and medium-to high-efficiency filter air supply system. Aluminum alloy sheet: Dust-free, expensive, 30-level purification system after high-efficiency filter air supply system.

  硬聚氯乙烯板:南京通风管道表面光滑,不起尘耐腐蚀、价格较贵、易老化 ,高效过滤器后送风管,表面处理车间排风系统。

  Hard polyvinyl chloride board: Nanjing ventilation pipe surface is smooth, dust-free, corrosion-resistant, expensive, easy to aging, high-efficiency filter rear air supply pipe, surface treatment workshop exhaust system。

  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,供电照明与建筑专业)首先应协商好空间分隔,定出每种管道的标高范围。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。解决各种通风管道相碰及协调的原则,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、热水管道。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。每种管道用一种彩色笔。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。为了减少投资,节省空间,降低层高,有些敷设无坡度要求的管道,可以穿梁敷设(如自来水管道,消防喷洒干管等)。

  For more complex civil buildings, in the design stage, each type of work (HVAC, water supply and drainage, power supply and lighting and architecture) should first negotiate the space separation and determine the elevation range of each kind of pipeline. Normally, it is not allowed to go beyond the limits set for itself. Consultation with other projects should be conducted when there is an individual pipeline crossing the boundary. The principle of solving the collision and coordination of various ventilation pipes is generally as follows: "Small pipes let big pipes, pressure let no pressure". For example, when a water pipe collides with an air pipe, the water pipe should turn. When the cold and hot water pipes collide with the sewer pipes, the cold and hot water pipes should be changed. Before the construction, the Engineer in charge of the equipment shall draw the pipelines of each type of work on a single plan. Each pipe uses a colour pen. Integrate the elevation at each intersection to see if there are any contradictions, find out in time, and solve the problem before installation. In order to reduce investment, save space and reduce floor height, some pipes without gradient requirements can be laid through beams (such as tap water pipes, fire spraying dry pipes, etc.).
