通風管道是工業與民用建筑的通風與空調工程用金屬或非金屬管道，是為了使空氣流通，下降有害氣體濃度的一種基礎設施。通風管道廠家在風管制作與裝置過程中，所用板材、型材以及其他首要制品材料，應符合規劃及相關產品現行標準的規矩，并使用出廠查驗合格證明，材料進場時應按現行有關標準進行查驗。

Ventilation pipes are metal or non-metal pipes used in ventilation and air conditioning engineering of industrial and civil buildings. They are an infrastructure for air circulation and reducing the concentration of harmful gases. In the process of air-conditioning operation and installation, the materials used by ventilation pipeline manufacturers, such as plates, profiles and other primary products, shall conform to the regulations of the current national standards for planning and related products, and shall use the certificate of qualifications for factory inspection. The materials shall be inspected in accordance with the relevant national standards in force when entering the field.

一、風管法蘭聯接

I. Flange connection of air duct

1、法蘭密封墊料。選用不透氣、不產塵、彈性好的材料，法蘭墊料應盡量削減接頭，接頭方法選用階梯形或企口形，接頭處應涂密封膠。法蘭之間的墊料應符合規劃要求。

1. Flange gasket. Choose materials that are impermeable, dustproof and elastic. Flange gaskets should reduce joints as much as possible. Joint methods should be ladder-shaped or enterprise-shaped. Sealant should be applied at joints. The gaskets between flanges shall meet the planning requirements.

2、法蘭聯接時，按要求墊好墊料，然后把兩個法蘭先對正，穿上幾顆螺栓并戴上螺母，不要上緊。再用尖沖塞進未上螺栓的螺孔中，把兩個螺孔撬正，直到一切螺栓都穿上后，擰緊螺栓。緊螺栓時應按十字交叉逐步均勻的擰緊。風管聯接好后，以兩頭法蘭為準，拉線檢查風管聯接是否平直。

2. When connecting flanges, pad the padding according to the requirements first, then put the two flanges in the right direction, put on several bolts and put on nuts, do not tighten. Then punch the bolts into the holes without bolts, pry the two holes straight, until all the bolts are put on, tighten the bolts. When tightening the bolt, it should be tightened evenly and gradually according to the cross. After the connection of the air duct is completed, the flange at both ends shall be taken as the standard, and the drawing line shall be checked to see whether the connection of the air duct is straight.

3、不銹鋼風管法蘭聯接的螺栓，宜用同原料的不銹鋼制成，如用一般碳素鋼，應按規劃要求噴涂涂料。

3. Bolts connected with flanges of stainless steel air ducts should be made of stainless steel with the same raw materials. If common carbon steel is used, coatings should be sprayed according to planning requirements

4、鋁板風管法蘭聯接應選用鍍鋅螺栓，并在法蘭兩頭墊鍍鋅墊圈。

4. Galvanized bolts should be selected for flange connection of aluminium sheet air duct, and galvanized gaskets should be cushioned at both ends of flange.

5、非金屬風管聯接兩法蘭端面應平行、緊密，法蘭螺栓兩頭應加鍍鋅墊圈;復合材料風管選用法蘭聯接時，應有防冷橋辦法。

5. The ends of flanges of non-metallic air ducts should be parallel and close, and the ends of flange bolts should be galvanized gaskets; when flanges of composite air ducts are selected, the method of cold-proof bridge should be adopted.

6、聯接法蘭的螺栓應均勻擰緊，其螺母宜在同一側。

6. The bolts of the connecting flange should be tightened evenly, and the nuts should be on the same side.

二、風管無法蘭聯接

2. Air duct can not be connected in blue

1、承插式風管聯接：適用于矩形或圓形風管聯接。先制作聯接管，然后刺進兩頭風管，再用自攻螺栓或拉鉚釘將其緊密固定，風管聯接處的四周應一致，無明顯的彎曲或褶皺;內涂的密封膠應無缺，外粘的密封膠帶應張貼結實、無缺無缺陷。

1. Socket-and-socket air duct connection: suitable for rectangular or circular air duct connection. Firstly, make connecting pipe, then pierce into two air ducts, then fix it tightly with self-tapping bolt or rivet. The air duct connection should be uniform around, without obvious bending or folding; the inner sealing glue should be intact, and the outer adhesive sealing tape should be sturdy and flawless.

2、薄鋼板法蘭方法風管聯接：要求彈性插條、彈簧夾或緊固螺栓的間隔不應大于150mm，且分布均勻，無松動現象。

2. Air pipe connection by thin plate flange method: Elastic inserts, spring clamps or fastening bolts should not be more than 150 mm apart, and should be evenly distributed without loosening.

3、插條式風管聯接：適用于矩形風管，要求聯接后的板面應平坦、無明顯彎曲。

3. Plug-type air duct connection: It is suitable for rectangular air duct, requiring that the plate surface after connection should be flat and without obvious bending.
