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

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。

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。

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。

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.

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)。

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.).
