通风管道出现故障，排风效果不好了怎么办呢？这时候需要对通风管道展开加固处理。通风管道加固能够保证通风管道在实际应用中内部静压的稳定性。
山东通风管道加工厂家在进行通风管道加固的过程中主要是从以下8个开展工作，并进行维修加固的。
What should I do if the ventilation pipe fails and the exhaust effect is not good? At this time, it is necessary to reinforce the ventilation pipe. The reinforcement of the ventilation pipe can ensure the stability of the static pressure in the actual application of the ventilation pipe. In the process of strengthening the ventilation pipe, Shandong ventilation pipe processing factory mainly carries out the work from the following 8, and carries out maintenance and reinforcement.
1).风管的加固可采用楞筋、立筋、角钢(内、外加固)、扁钢、加固筋和管内支撑等形式。
the reinforcement of air duct can be in the form of corrugated bar, vertical bar, angle steel (internal and external reinforcement), flat steel, reinforcement bar and pipe internal support.
2).圆形风管(不包括螺旋风管)直径大于等于8mm，且其管段长度大于1250mm或总表面积大于4m2均应采取加固措施。
if the diameter of circular air duct (excluding spiral air duct) is greater than or equal to 8mm, and the length of pipe section is greater than 1250mm or the total surface area is greater than 4m2, reinforcement measures shall be taken.
3).矩形风管边长大于630mm、保温风管边长大于800mm,管段长度大于1250mm或低压风管单边面积大于1.2m2、中压、高压风管大于1.0㎡，均应采取加固措施。
if the side length of rectangular air duct is greater than 630mm, the side length of insulation air duct is greater than 800mm, the length of pipe section is greater than 1250mm, or the area of single side of low-pressure air duct is greater than 1.2m2, and the area of medium pressure and high-pressure air duct is greater than 1.0m2, reinforcement measures shall be taken.
4).非规则椭圆风管的加固，应参照矩形风管执行。
the reinforcement of irregular elliptical duct shall refer to rectangular duct.
5).楞筋或楞线的加固，排列应规则，间隔应均匀，板面不应有明显的变形。
the reinforcement of corrugated bars or lines shall be arranged in a regular way, with even spacing and no obvious deformation on the board surface.
6).角钢、加固筋的加固，应排列整齐、均匀对称，其高度应小于或等于风管的法兰宽度。角钢、加固筋与风管的铆接应牢固、间隔要均匀。不应大220mm，相交处应连接为一体。
the reinforcement of angle steel and reinforcing bar shall be arranged orderly, evenly and symmetrically, and its height shall be less than or equal to the flange width of air duct. The riveting of angle steel, reinforcing bar and air duct shall be firm and evenly spaced. It shall not be larger than 220mm, and the intersection shall be connected as a whole.
7).管内支撑与风管的固定应牢固，各支撑点之间或风管的边沿或法兰的间距应均匀，不应大于950mm。
the support in the pipe and the air pipe shall be fixed firmly, and the spacing between each support point or the edge or flange of the air pipe shall be uniform and not more than 950mm.
8).中压和高压系统的风管管段，其长度大于1250mm时，还应有加固框进行补强。高压系统金属风管的单咬口缝，还应有防止咬口缝胀裂的加固或补强措施。
when the length of the air duct section of the medium pressure and high pressure system is greater than 1250mm, it shall be reinforced by a reinforcing frame. For the single seam of metal air duct in high pressure system, reinforcement or reinforcement measures shall be taken to prevent the seam from expanding and cracking.
山东通风管道加工维修厂家经过多年的实践经验总结出：在实际通风管道加固的过程中，需要根据压力大小、尺寸大小选择相应的加固方式，加固方式的选择，对更终通风管道的使用寿命起到决定性作用。
After many years of practical experience, Shandong ventilation pipe processing and maintenance factory summed up that: in the process of actual ventilation pipe reinforcement, it is necessary to select the corresponding reinforcement method according to the pressure and size, and the selection of reinforcement method, which plays a decisive role in the service life of the final ventilation pipe.
