镀锌钢板和镀锌铁皮只是一种材质！俗称白铁皮通风管道。有单面镀锌和双面镀锌的，需要根据实际情况选择锌层厚度，表面：有花，无花，有油，无油，镀锌通风管道主要看他的镀锌板厚度和抗氧化能力(锌层厚度）。下面济南铁皮风管加工人员来讲讲铁皮通风管道加工的细节：

Galvanized steel plate and galvanized iron sheet are just one material! Commonly known as tin ventilation ducts. For single-sided and double-sided galvanized pipes, the thickness of the zinc layer needs to be selected based on the actual situation. The surface: with or without flowers, with or without oil. The galvanized ventilation pipeline mainly depends on the thickness of the galvanized sheet and its oxidation resistance (zinc layer thickness). Next, Jinan iron sheet air duct processing personnel will talk about the details of iron sheet ventilation duct processing:

1、板材接缝处从一端另一端按对中位置粘上压敏铝箔胶带,压敏胶带粘在一边的宽度不小于20mm。

1. Stick pressure-sensitive aluminum foil tape from one end to the other end at the seam of the board according to the alignment position, and the width of the pressure-sensitive tape adhered to one side shall not be less than 20mm.

2、清洁板材切割面的粉末,按空调风管加工任务单检查风管面板是否符合设计要求。

2. Clean the powder on the cutting surface of the board, and check whether the air duct panel meets the design requirements according to the air conditioning duct processing task sheet.

3、清洁板材切割面的粉末、油渍、水渍、灰尘,用毛刷在切割面上涂刷胶粘剂。

3. Clean the powder, oil stains, water stains, and dust on the cutting surface of the board, and use a brush to apply adhesive on the cutting surface.

4、将风管面板按设计要求粘合,待涂胶不粘手时.并用刮板压平.对难以刮平的局部,可用木锤轻轻锤平。

4. Glue the air duct panel according to the design requirements, and when the adhesive does not stick to the hands, use a scraper to flatten it. For areas that are difficult to flatten, use a wooden hammer to gently flatten them.

5、检查板材接缝粘接是否达到质量规定。

5. Check whether the joint bonding of the board meets the quality requirements.

制作工艺要求

Production process requirements

1、白铁皮风管加工宜选用压槽连接或焊接，不能焊接。

1. The processing of white iron sheet air ducts should choose groove connection or welding, and welding is not allowed.

2、风管实木板材拼接的咬口缝应分离，不能有十字型拼接缝。

2. The bite seam of the solid wood panel splicing of the air duct should be separated and there should be no cross shaped seam.

3、咬口缝紧密、总宽一致，压边垂直，弧型均匀且两侧面垂直面。

3. The bite seam is tight, the overall width is consistent, the edge pressing is vertical, the arc shape is uniform, and both sides are perpendicular.

4、通风风管无明显扭曲与翼角，表面应整理平整，凹凸不能超过8mm。

4. The ventilation duct should have no obvious distortion or wing angles, and the surface should be neat and flat, with no more than 8mm bumps.

5、通风风管孔径或外边长容许误差为负偏差，当通风风管大直径小于等于630mm时，为-1mm；当超出630mm时，为-2mm。

5. The allowable error for the aperture or outer length of the ventilation duct is a negative deviation. When the large diameter of the ventilation duct is less than or equal to 630mm, it is -1mm; When it exceeds 630mm, it is -2mm.

6、立管平面度的容许误差为1mm，矩形通风风管二根平行线长度差值不能超出2mm。

6. The allowable error in the flatness of the riser is 1mm, and the difference in length between the two parallel lines of the rectangular ventilation duct cannot exceed 2mm.

7、不锈钢风管直径超出630mm、隔热保温保温风管直径超出800mm，管一段距离超出1250mm或低压通风风管一侧平占地面积超出1.2㎡、中、高压通风风管超出1.0㎡，都应选用固定不动防范措施。还有什么事项就来我们网站http://www.sftfgd.com咨询吧！

7. Stainless steel air ducts with a diameter exceeding 630mm, thermal insulation and insulation air ducts with a diameter exceeding 800mm, a distance exceeding 1250mm, or a flat area on one side of the low-pressure ventilation duct exceeding 1.2 square meters, or medium and high-pressure ventilation ducts exceeding 1.0 square meters, all should adopt fixed and immovable prevention measures.
