熱鍍鋅通風管在城市建設中占據關鍵影響力。
Hot dip galvanized ventilation pipe occupies a key influence in urban construction.
1.工程施工前的提前準備
1. Preparation before construction
俗話說得好“磨刀技巧不誤劈柴功”。充足的提前準備是確保風管安裝品質的前提條件。凈化處理風管提前準備生產制造時，不論是廠內集中化生產制造或是當場生產制造，都需要確保當場清理封閉式，有達標的照明燈具和照明燈具標準。此外，生產加工好的方鋼管應當心運送，盡量減少環境污染。
As the saying goes, "the skill of sharpening a knife does not miss the skill of chopping firewood". Adequate preparation in advance is the prerequisite to ensure the installation quality of air duct. When the purification treatment air duct is prepared for production and manufacturing in advance, whether it is centralized production and manufacturing in the plant or on the spot production and manufacturing, it is necessary to ensure that the closed type is cleaned on the spot and there are standard lighting lamps and lighting lamps. In addition, the produced and processed square steel pipes should be transported carefully to minimize environmental pollution.
2.管道原材料的挑選
2. Selection of pipeline raw materials
風管原材料的挑選對風管的施工質量也是有非常大的危害。一般來說，為了更好地確保風管的凈重，務必選用厚度較小的風管，但風管的規格和工作壓力級別務必綜合性考慮到。從設計方案的視角看來，特別注意的是，一個系統軟件能夠 幾個筒體薄厚相匹配不一樣的負壓水準。
The selection of air duct raw materials is also very harmful to the construction quality of air duct. Generally speaking, in order to better ensure the net weight of the air duct, the air duct with smaller thickness must be selected, but the specification and working pressure level of the air duct must be comprehensively considered. From the perspective of design scheme, it should be noted that a system software can match the thickness of several cylinders with different negative pressure levels.
3.風管水準聯接
3. Horizontal connection of air duct
風管水準聯接有一定的獨特性。這類接口方式能夠 說成增加風管長短的方式，還具備提高風管彎曲剛度、維持風管水準規格的功效。水準聯接一般 是角活套法蘭。這類聯接在于墻面的薄厚，也在于墻面的聯接和加固。
The horizontal connection of air duct has certain uniqueness. This kind of interface mode can be described as a way to increase the length of the air duct, and also has the effect of improving the bending stiffness of the air duct and maintaining the standard specification of the air duct. Horizontal connection is generally angle looper flange. This kind of connection lies not only in the thickness of the wall, but also in the connection and reinforcement of the wall.
4.風管縱縫
4. Longitudinal joint of air duct
風管縱縫方式可依據具體情況挑選。中底壓管道中常會選用扣子牙齒咬合聯接。針對矩形框管道，沒有連接頭堵塞的工作壓力等級。因而，選用扣子牙齒咬合能夠 節約反邊工藝流程。現階段，大部分軟管是豎向接縫處。按鍵用以聯接。可選用螺栓、自攻螺絲、焊接、壓紋、壓印等方式 擰緊立縫和帽型立縫。
The longitudinal joint mode of air duct can be selected according to specific conditions. The middle and bottom pressure pipes are usually connected by the bite of buttons and teeth. For rectangular box pipes, there is no working pressure level with connector blockage. Therefore, the selection of button teeth can save the reverse edge process. At this stage, most hoses are at vertical joints. The key is used to connect. Bolts, self tapping screws, welding, embossing, embossing and other methods can be used to tighten the vertical seam and cap type vertical seam.
5.風管儲放
5. Air duct storage
預制構件風管應妥當儲放，防止二次污染。支管可以用塑料薄膜等橡膠密封件密封性，隨后將管道歸類堆積。風管應用前留意清理，保證表面耐腐蝕，干躁后無真空泵。
The air duct of prefabricated components shall be properly stored to prevent secondary pollution. The branch pipe can be sealed with rubber seals such as plastic film, and then the pipe can be classified and stacked. Pay attention to cleaning the air duct before application to ensure that the surface is corrosion-resistant, and there is no vacuum pump after dryness.
