铁皮风管应尽可能按直线布置。这一条要求对任何风管系统的布置都是重要的准则。直线布置的风管系统，在运行能耗和初投资两方面都是低的。从的观点分析，空气总是"希望"走直线，这将减少能耗。从费用的观点分析，直管段的费用比各种弯头等管件要少很多。

Iron sheet air ducts should be arranged as straight as possible. This requirement is an important criterion for the layout of any duct system. The straight-line layout of the air duct system has low operating energy consumption and initial investment. From the perspective of energy conservation, air always "hopes" to go straight, which will reduce energy consumption. From a cost perspective, the cost of straight pipe sections is much lower than that of various elbows and other fittings.

开裂是铁皮风管在使用的过程中常见的问题之一。实际上，铁皮风管专用胶的粘接强度很高，在安装使用中，如果发现部份开裂现象，济南铁皮风管加工人员提醒，这一般是因为：

Cracking is one of the common problems in the use of iron sheet air ducts. In fact, the adhesive strength of the iron sheet air duct special adhesive is very high. If some cracks are found during installation and use, Jinan iron sheet air duct processing personnel remind that this is generally because:

1、风管板质量不合格，强度差，变形度大，制作成风管后尺寸稳定性差，易开裂；

1. The air duct board has unqualified quality, poor strength, large deformation, poor dimensional stability after being made into an air duct, and is prone to cracking;

2、制作与施工中应采用专用胶，但大多数仿制企业不知道或不懂得专用胶的配制，认为氧化镁加卤水就是胶粘剂，这种胶粘剂制作与安装的风管肯定开裂；

2. Special adhesives should be used in production and construction, but most imitation enterprises do not know or understand the preparation of special adhesives. They believe that magnesium oxide and brine are adhesives, and the air ducts produced and installed with this adhesive will definitely crack;

3、铁皮风管施工专用胶的配制不能太少或者太稠。粘接时缺胶或胶体过稠，以及伸缩节布置不合理都易造成铁皮风管开裂。

3. The preparation of special adhesive for the construction of iron sheet air ducts should not be too small or too thick. Lack of adhesive or excessive viscosity during bonding, as well as improper arrangement of expansion joints, can easily cause cracking of the iron sheet air duct.

发现铁皮风管开裂可以用修补胶修补。修补方法为：

Cracks in the iron sheet air duct can be repaired with repair glue. The repair method is:

1）在开裂线50mm周围用砂皮打磨，并除去尘粒；

1) Grind with sand around the crack line 50mm and remove dust particles;

2）将修补胶压入开裂缝；

2) Press the repair adhesive into the crack;

3）在铁皮风管开裂处贴上玻布。用修补胶修理平整、美观。

3) Apply glass cloth to the cracked area of the iron sheet air duct. Repair flat and aesthetically pleasing with repair adhesive.
