　　普通冷軋鋼板：便宜、易腐蝕 ，一般通風(fēng)用送風(fēng)、回風(fēng)、新風(fēng)、排風(fēng)、排煙系統(tǒng)。鍍鋅鋼板： 耐腐蝕性相比剛辦好，但在加工過程中鐵皮 對溫濕度要求較高場合的送回風(fēng)系統(tǒng)，超凈系統(tǒng)中效過濾，易脫落，油漆不易附著 器前和中效過濾器之間的送風(fēng)系統(tǒng)。鋁合金板：不起塵、貴， 30級凈化系統(tǒng)過濾器之后送風(fēng)系統(tǒng)。

　　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：南京通風(fēng)管道表面光滑，不起塵耐腐蝕、較貴、易老化 ，過濾器后送風(fēng)管，表面處理車間排風(fēng)系統(tǒng)。

　　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.

　　對于比較復(fù)雜的民用建筑，在設(shè)計階段，各工種(暖通、給水排水，供電照明與建筑)應(yīng)協(xié)商好空間分隔，定出每種管道的標(biāo)高范圍。一般情況下不得越出給自己規(guī)定的界限。遇有個別管段要越界時應(yīng)與其他工程協(xié)商。解決各種通風(fēng)管道相碰及協(xié)調(diào)的原則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風(fēng)管相撞，則應(yīng)當(dāng)自來水管拐彎。冷、熱水管與下水管相碰，則應(yīng)改變冷、熱水管道。施工前應(yīng)設(shè)備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種管道用一種彩色筆。在各交點處綜合其標(biāo)高，看是否有矛盾之處，及時發(fā)現(xiàn)，將問題解決在安裝之前。為了減少投資，節(jié)省空間，降低層高，有些敷設(shè)無坡度要求的管道，可以穿梁敷設(shè)(如自來水管道，消防噴灑干管等)。

　　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.).
