在不少场景中，大家可能会见到，有些工作人员在安装一些圆形或者矩形的通风管。它其实是用于空气输送和分布的管道系统，为人们带来了很多便利。下面来看看金属板制风管加固的七点事项吧。

In many scenes, you may see that some staff are installing some circular or rectangular ventilation pipes. It is actually a pipeline system used for air transmission and distribution, which brings a lot of convenience to people. Let's take a look at the seven points for strengthening the metal plate air duct.

1）风管大边尺寸在630～1000mm时，直接在生产线压筋加固，排列应规则，间隔应均匀，板面不应有明显的变形。

1) When the size of the large side of the air duct is 630~1000mm, the reinforcement shall be directly pressed on the production line, the arrangement shall be regular, the spacing shall be uniform, and the plate surface shall not have obvious deformation.

2）当济南通风管道大边尺寸在1000mm以上时，可采用角钢、扁钢、钢管、Z形槽、加固筋、通丝螺杆等进行管内外加固。

2) When the large side size of Jinan ventilation pipe is more than 1000mm, angle steel, flat steel, steel pipe, Z-shaped groove, reinforcing bar, through-wire screw, etc. can be used to reinforce the inside and outside of the pipe.

3）角钢或加固筋的加固，其高度应小于或等于风管法兰高度，排列应整齐，间隔应均匀对称，且不大于220mm，与风管的铆接应牢固。

3) For the reinforcement of angle steel or reinforcing bar, its height should be less than or equal to the height of the air duct flange, the arrangement should be neat, the spacing should be uniform and symmetrical, and not more than 220mm, and the riveting with the air duct should be firm.

4）管内用通丝螺杆支撑加固，其专用垫圈对外保温风管置于风管内壁，对不保温风管或内保温风管，则放在风管外壁，通丝螺杆宜设置在风管处，风管断面较大时，应在靠近法兰的两侧各加一根通丝螺杆支撑加固。

4) The inner part of the duct shall be supported and reinforced with through-wire screw. Its special gasket shall be placed on the inner wall of the duct for external insulation. For non-insulated duct or internal insulation duct, it shall be placed on the outer wall of the duct. The through-wire screw shall be set at the center of the duct. When the duct section is large, a through-wire screw shall be added on both sides near the flange for support and reinforcement.

5）济南通风管道断面＞1250*630时，为了保持相邻壁面互相垂直，宜在风管内四角采用90℃斜支撑加固。

5) When the section of Jinan ventilation duct is more than 1250 * 630, in order to keep the adjacent walls perpendicular to each other, 90 ° C diagonal bracing should be used at the four corners of the air duct for reinforcement.

6）中压和高压系统风管，其长度大于1250mm时，应采用加固框补强。

6) When the length of the air duct of the medium-pressure and high-pressure systems is greater than 1250mm, the reinforcement frame shall be used for reinforcement.

7）金属板制通风管道组装加固规格表。

7) Specification for assembly and reinforcement of metal sheet ventilation duct.

注意：在对通风管道进行安装之前，人们需要先对通风管道的情况做具体的了解，看看通风管道的各项指标是否合格，保证通风管道的排风口具有一个平整的表面，那个平整的表面可能在制作上有相应的误差，但误差须控制在2毫米，如果排风口的误差大于2毫米，那就说明通风管道是不合格的，这种通风管道不能使用。更多相关事项就来我们网站http://www.jntfgd.com咨询吧！

Note: Before installing the ventilation duct, people need to make a specific understanding of the condition of the ventilation duct, see whether the indicators of the ventilation duct are qualified, and ensure that the exhaust port of the ventilation duct has a flat surface, which may have a corresponding error in manufacturing, but the error must be controlled at 2mm. If the error of the exhaust port is greater than 2mm, it means that the ventilation duct is unqualified, This ventilation duct cannot be used.
